A 24-70 mm lens offers probably one of the most versatile zoom ranges, a put-it-on-the-camera-and-leave-it range. So here comes Tamron with its new SP 24-70 mm f/2.8 Di VC USD G2 lens for full-frame DSLR cameras. The constant f/2.8 aperture makes it even more interesting.
The lens features Dual MPU (Micro Processing Units) to provide rapid autofocusing with improved accuracy and the highest vibration compensation performance of any lens in its class, says the company (CIPA level of 5 stops).
The use of specialized, high quality glass materials (offering greater optical transmittance) for the lens element are said to assure superior colour reproduction and greater sharpness, while the application of Tamron’s nanotechnology-based eBAND Coating substantially curbs the ghosting and flare that are prone to occur in backlit photography, successfully improving the overall optical performance of the lens, Tamron notes. Additionally, the lens provides the added conveniences of protective fluorine coating, moisture-resistant construction and a locking lens hood.
The lens’ optical construction consists of 17 elements in 12 groups using two XR (Extra Refractive Index) elements, three LD (Low Dispersion) elements, three GM (Glass-Molded aspherical), and one hybrid aspherical lens element. Together they are claimed to minimize axial chromatic aberrations, transverse chromatic aberrations, spherical aberrations and distortion, and allow a compact design that achieves superior image quality.
The lens is equipped with Tamron’s VC (Vibration Compensation) system. Adding an MPU dedicated to VC processing unleashes a new-generation algorithm, says Tamron, ensuring the highest vibration compensation ability in the class.
An electromagnetic diaphragm system, which has been a standard feature for Canon-mount lenses, is now employed in Nikon-mount lenses.
The Tamron SP 24-70 mm f/2.8 Di VC USD G2 lens will be available in Canon and Nikon mounts. Nikon mount will be available in August, the Canon mount in September.
The company says the lens includes “the most advanced optical and mechanical designs,” an HLD (High/Low torque modulated Drive) for the AF system, and Vibration Compensation system.
A new lens barrel design utilizing three-step extensions was developed to enable the necessary elongation to produce a 22.2x zoom ratio. Compared to the conventional approach, the division into a larger number of cams ensures comfortable operation and stability while zooming, Tamron advises.
The power-saving HLD motor produces “outstanding” driving torque, and adjusts motor rotation from low to high speed to enable accurate and quiet focusing. The HLD motor takes up less space thanks to its small size and circular arc shape that allows the size of the lens to be reduced.
The electromagnetic diaphragm system, which has been a standard feature for Canon-mount lenses, is now employed in Nikon-mount lenses. More precise diaphragm and aperture control is possible because the diaphragm blades are driven and controlled by a motor through electronic pulse signals.
The lens also features moisture-resistant construction, and the Zoom Lock mechanism prevents undesired movement of the lens barrel under its own weight when the camera is angled downward while walking.
The device is compatible with the TAP-in Console, an optional accessory product. This provides a USB connection to a personal computer, enabling the user to easily update the lens’s firmware as well as to customize features, including fine adjustments to the AF and VC.
The lens is 123.9 mm / 121.4 mm long (Canon/Nikon) and weighs 710 g / 705 g (Canon/Nikon).
Tamron says its 18-400 mm f/3.5-6.3 Di II VC HLD lens in Canon and Nikon mounts will be available in late July.
The new lens has improved optical performance and new features, including the VC (Vibration Compensation), moisture-resistant construction, and Fluorine coating, as well as the first implementation of Tamron’s new HLD (High/Low Torque Modulated Drive Motor). The lens also sports a new exterior design.
The optical design consists of 16 lens elements in 11 groups. Special lens elements are utilized in an optimum configuration of one LD (Low Dispersion) lens element, one XLD glass element, one molded glass aspherical element, and one hybrid aspherical lens. While curbing an increase in the size of the optical system, the company says the new lens very effectively compensates for a wide variety of aberrations in the entire zoom range, including transverse chromatic aberration, comatic aberration and distortions that tend to become more prominent with a wide-angle lens.
BBAR (Broad-Band Anti-Reflection) Coating and the optical design inhibit internal reflections in the lens barrel and also curb the effects of harmful light rays that tend to occur with a wide-angle lens, achieving excellent resistance against ghosting and flare seen in backlighting situations.
Optimizing the actuator and the control algorithm has made it possible to incorporate VC while maintaining the compact design of the previous model.
The HLD is capable of smoothly controlling the AF mechanism even with the lens’ large focusing lens elements. When shooting in AF mode, the Full-time Manual Focus override allows you to instantly make fine focusing adjustments manually, without having to switch between modes.
The front lens element is coated with a protective fluorine compound that is water- and oil-repellant. The lens surface is easier to wipe clean and is less vulnerable to the damaging effects of dirt, dust, moisture and fingerprints. There also are leak-proof seals throughout the lens barrel.
An electromagnetic diaphragm system, which has been a standard feature for Canon-mount lenses, is now employed in Nikon-mount lenses. More precise diaphragm and aperture control is possible.
The optional TAP-in Console provides a USB connection to your personal computer, enabling you to easily update your lens’s firmware as well as customize features including fine adjustments to the AF and VC.
Filter size is 77 mm, lens length is 84.6 mm (Canon) / 82.1 mm (Nikon), and weight is 440 g.
The Tamron 10-24mm f/3.5-4.5 Di II VC HLD in Canon and Nikon mount models is slated for late February launch in Japan, with Canada to follow.
Immediately after announcing a 70-300 mm lens that’s apparently for the Japanese market only, Tamron has unveiled the SP 70-200 mm f//2.8 Di VC USD G2 which definitely will be coming to Canada.
Designed for full-frame DSLR cameras, the new lens was developed by substantially enhancing the features of its predecessor, says the company. These included a thorough review of the optical, mechanical and electronic designs to enhance increase autofocus speed and precision, reinforce VC (Vibration Compensation) functions and to shorten MOD.
New features include eBAND coating, moisture-proof and dust-resistant construction, Fluorine coating and compatibility with tele converters.
The lens design features a metal-based barrel for improved handling and ease-of-use.
Both the resolution and contrast reproduction performance have been improved. Bokeh has been enhanced and expanded. The optical design consists of 23 elements in 17 groups. Optimum deployment of XLD (eXtra Low Dispersion) and LD (Low Dispersion) glass elements are said to thoroughly eliminate chromatic aberrations across the entire zoom range, while ensuring uniform, high-level image quality even on the periphery of the image plane.
The new lens is also fully compatible with the 1.4x (TC-X14) and 2.0x (TC-X20) teleconverters.
Utilizing Tamron’s original VC (Vibration Compensation) system, which uses a moving coil mechanism, further reinforcement of the drive system power and control performance now delivers an image stabilization performance of 5 stops, says Tamron. Also, the VC system offers three VC modes, including one mode exclusively for panning.
The lens is equipped with a USD (Ultrasonic Silent Drive) ring-type ultrasonic motor. Incorporating two advanced, high performance microcomputers and optimizing the algorithm has improved both the focusing speed and accuracy compared with the previous model. Additionally, Full-time Manual Focus override lets photographers shooting with AF instantaneously make fine focusing adjustments using MF without switching modes.
Improvements made to the focus cam and zoom cam inside the lens barrel have reduced the MOD from 1.3 m (50.7 in) in the older model to 0.95 m (37.4 in) for the new lens, which has a maximum magnification ratio of 1:6.1.
The eBAND (Extended Bandwidth & Angular-Dependency) coating combines a nano-structured layer with an extremely low refractive index with the conventional multiple-layer coatings. Optimized and exclusively designed for this new zoom, the eBAND Coating provides superior anti-reflection performance, effectively reducing any flare and ghosting, Tamron says.
The front surface of the lens element is coated with a protective fluorine compound that is water- and oil repellant. The lens surface is easier to wipe clean and less vulnerable to the damaging effects of dirt, dust, moisture and fingerprints.
An electromagnetic diaphragm system, which has been a standard feature for Canon-mount lenses, is now available for in Nikon-mount lenses. More precise diaphragm and aperture control is possible because the diaphragm blades are driven and controlled by the motor through electronic pulse signals.
A lightweight and easy-to-hold tripod mount is compatible with Arca-Swiss style quick release plates.
A new textured grip and Arca-Swiss style tripod interface enhances both speed and utility. Because the tripod mount is made of lightweight magnesium, it is much easier to carry.
The new lens is compatible with the TAP-in Console, an optional accessory, providing a USB connection to a personal computer enabling users to easily update the lens firmware as well as customize features, including fine adjustments to the AF and VC.
Filter size is 77 mm, weight is 1,500g (Canon) / 1,485g (Nikon).
The Tamron SP 70-200 mm lens is due for late February release in Japan in Canon and Nikon mounts, with Canadian availability to follow.
Tamron has updated its “big gun” with the release of the SP 150-600mm f/5-6.3 Di VC USD G2. This second generation “G2” lens adds improvements to several features including speed and accuracy of AF and VC (Vibration Compensation). Also, several new features have been added: Flex Zoom Lock mechanism, Fluorine Coating and optional teleconverters. The new lens features a metal lens barrel.
The Canon and Nikon mount models will be launched simultaneously, with the Sony version to come later.
Three LD (Low Dispersion) lens elements completely eliminate axial and transverse chromatic aberrations, says the company. The design also features upgraded optical construction (21 elements in 13 groups) and leverages improvements in manufacturing technology. As a result, says Tamron, the lens delivers high resolution, improved sharpness and overall better performance.
Tamron’s eBAND Coating is said to eliminate ghosting and flare. eBAND (Extended Bandwidth & Angular-Dependency) Coating is a nano-structured layer deployed on the lens element surface. In addition to regular anti-reflection coatings, eBAND Coating offers higher light transmission and significant improvement in anti-reflection characteristics, especially against angulated incident rays. Combined with of BBAR (Broad-Band Anti-Reflection) coatings, flare and ghosting are reduced to imperceptible levels, notes the company.
Minimum Object Distance is now 2.2 m (86.6 in), compared to 2.7 m for the previous model. AF speed is faster and much more responsive with moving subjects. The lens is equipped with a USD (Ultrasonic Silent Drive) ring-type motor that delivers excellent responsiveness and control. AF speed is significantly improved, and it enables accurate high-speed focus even when capturing moving subjects.
When shooting with AF, the Full-time Manual Focus override allows you to instantly make fine focusing adjustments manually, without having to switch between modes.
VC performance is now 4.5 stops and offers three modes optimized for different situations.
Tamron has launched two teleconverters exclusively for select Tamron lenses. Tele Converter 1.4x (TC-X14) increases the focal length by a factor of 1.4x, while Tele Converter 2.0x (TC-X20) doubles the focal length.
Canon and Nikon mounts are first to be released.
The 2.0x model uses one LD (Low Dispersion) lens element to suppress aberrations. BBAR (Broad-Band Anti-Reflection) coatings are deployed on both models to help minimize ghosting and flare.
Autofocus functions normally with compatible lenses. VC (Vibration Compensation) performance is maintained.
The new teleconverters are said to be ideal for use in outdoor photography when matched with any lens that has a Moisture-Resistant Construction because special seals that are dust-resistant and moisture-proof are used at every joint and seam.
The barrel frame of the teleconverters is made of die cast aluminum, except for some parts of the exterior finish, to maintain extra strength when used with large lenses. The design utilizes a bayonet mount made of brass on the camera side and stainless steel on the lens side to ensure excellent durability even with repeated mountings and detachments.
The 1.4x model features 6 elements in 3 groups, while the 2.0x model has 9 elements in 5 groups.
Tamron has announced what it claims to be the world’s first 85 mm f/1.8 lens with VC for full-frame DSLR cameras, offering the “ultimate correction” of aberrations and excellent resolving power with balanced bokeh. The new 90 mm lens is a macro, also with VC (vibration compensation).
The SP 85 mm f/1.8 Di VC USD, to use its full name, uses LD (Low Dispersion) and XLD (Extra Low Dispersion) glass elements. Tamron says these elements have “virtually eliminated” on-axis and lateral chromatic aberrations that might otherwise appear as colour fringing. In addition, by thoroughly reducing comatic aberrations (distortion of off-axis point source) and astigmatism, subjects that appear as a distinct point source will be captured as a distinct point source even at the edges and corners of the frame, says the company.
Optical construction is 13 elements in 9 groups.
Two highly developed lens coating technologies, eBAND (Extended Bandwidth & Angular-Dependency) which uses nanotechnology, and BBAR (Broad-Band Anti-Reflection), combine to increase light transmission and to reduce flare and ghosting to “imperceptible levels.” Additional techniques are employed to prevent reflections inside the lens barrel so that the lens delivers high contrast, sharp and clear images. Tamron says this lens clearly captures detailed tones even in the shadows.
In addition, moisture-resistant construction is said to prevent intrusion of moisture, and a highly durable fluorine coating has been applied to the top element surface to prevent condensation and repel smudge-causing substances.
An electromagnetic diaphragm system, which has been a standard feature for Canon-mount lenses, is now employed in Nikon-mount lenses. More precise diaphragm and aperture control is possible because the diaphragm blades are driven and controlled by a motor through electronic pulse signals.
Fast, quiet AF is achieved by employing a USD (Ultrasonic Silent Drive) ring-type ultrasonic motor which enables remarkably precise focusing drive with high torque and responsiveness. Thanks to the absence of reduction gears in USD, there is no backlash and no unnecessary back-and-forth movement. The control software program for the USD actuator has been revised to provide substantially improved focusing speed and accuracy when using AF. In addition, Full-time Manual Focus override is available at any point during the autofocus operation for deliberately shifting focus without switching the AF-MF. Whether overriding the autofocus or focusing completely manually, the focusing ring turns smoothly and evenly.
You can update firmware, customize autofocus positions and adjust the mechanical setup and preferences of the lens by attaching it to the new TAP-in Console and connecting it via USB to a personal computer. (The TAP-in Console is an optional accessory.)
Supplied with SILKYPIX Developer Studio 4.0, editing software that features correction menus for various aberrations (lateral colour, distortion, relative illumination) based on the optical design data of this specific lens. In addition, lens profile information has been supplied to Adobe to facilitate selecting the precise lens data required for more sophisticated adjustments in RAW processing when using Adobe Photoshop and Lightroom.
Tamron’s SP 90 mm f//2.8 Macro 1:1 Di VC USD is an upgrade of the company’s previous 90 mm macro lens. XY-Shift compensation has been added to reinforce VC functionality, further improving image stabilization from infinity to macro. Advancements in USD control software have also increased AF focusing speed, and optimally fine-tuned for various framing conditions. In addition, a high standard of moisture-proof and dust-resistant construction has been added to prevent intrusion of dust or moisture, and a highly durable fluorine coating has been applied to the top element surface to prevent condensation and repel smudge-causing substances.
Inheriting the optical design of the previous 90 mm macro (14 elements in 11 groups), the new model is said to deliver the same resolving power and soft background blur effects. The advanced construction includes one LD (Low Dispersion) specialized glass element that maximally limits the dispersion properties of light and two XLD (eXtra Low Dispersion) glass elements to correct dispersion properties to an even greater extent. The special elements optimally compensate for on-axis and lateral chromatic aberrations from macro shooting range to infinity. The company says the design ensures the best imaging performance at any range by adopting the Floating System which shifts the location of a group of elements to the best possible position as the focusing group travels relative to shooting distances.
Tamron also notes it hasn’t altered the lens’ blur effects; the company says the lens achieves both sharp, vivid images and spectacular background blur effects.
An accelerometer has been integrated into the VC to compensate for shakes on the x-y plane. In unison with a gyro sensor, the accelerometer detects and enables motion compensation for camera shake, providing maximum efficiency in image stabilization optimized for all distance ranges from infinity to macro.
The control software program for the USD (Ultrasonic Silent Drive) actuator has been revised to provide substantially improved focusing speed and accuracy when using AF. The USD quickly addresses any out-of-focus condition caused by back-and-forth camera movement (which commonly occurs during macro photography) ensuring better results when shooting at close range.
The water and oil repellant coating applied to the front element surface allows instant removal of dirt or smudges with ease. The coating also provides a reasonable level of durability, and will sustain its effectiveness for years.
Two advanced coating technologies, both providing outstanding anti-reflection performance, are applied to critical element surfaces for maximum light transmission – eBAND (Extended Bandwidth & Angular-Dependency) Coating boasts outstanding anti-reflection performance across nearly the entire range of visible rays, and BBAR (Broad-Band Anti-Reflection) Coating utilizes traditional multi-layered, anti-reflection technology. This combination, says the company, “virtually eliminates” extraneous reflections and substantially reduces ghosting and flare which enables the lens to achieve flawless, crystal clear images.
The new 90 mm macro has a focus limiter that makes it possible to shorten the time for accurately focusing on a subject when the working range is known. The lens also features an internal focusing system, so the overall length of the lens never changes, not even when focusing. As a result, the user is assured of a comfortable working distance of at least 139 mm (5.5 in.) from the front of the lens. In addition, the lens is equipped with a full-time manual focus override mechanism which makes it possible to flexibly choose focal points. Even with the AF driving system in action, it is possible to instantaneously override it to make manual fine focusing adjustments without switching the AF-MF mode back and forth.
As with the 85 mm noted above, you can update firmware, customize autofocus positions and adjust the mechanical setup and preferences of the 90mm lens by simply attaching it to the TAP-in Console (an optional accessory).
Included in the package is SILKYPIX Developer Studio, and lens profile information has been supplied to Adobe.
The Tamron SP 85 mm f/1.8 Di VC USD is scheduled for launch late in March in Canon and Nikon versions, with the Sony (non-VC) version coming later.
The SP 90 mm f//2.8 Macro 1:1 Di VC USD is scheduled for almost immediate availability in Nikon and Canon versions, with the Sony (non-VC) model coming later.
Tamron has announced two new SP lenses, both fast, fixed focal length models, delivering what the company calls “ultimate performance.” And, apparently, these two are just the first in a relaunched SP line.
Sporting a totally revamped external appearance, the new lenses are compatible with full-frame DSLR cameras, although both can be used with APS-C cameras as well.
The SP 35 mm f/1.8 Di VC USD and SP 45 mm f/1.8 Di VC USD will be launched late this month in Canon and Nikon mounts, with a Sony mount version to follow later. The Sony version will not include Vibration Compensation (VC) since that’s built in to the camera.
In 1979, Tamron unveiled the first SP Series lens in 1979, a 90 mm f/2.5 Macro, with several other lenses following. But the company says it wanted to redefine the SP line, especially with the advent of new technologies.
All of the key performance criteria were redefined, says Tamron, to achieve the ultimate in optical performance. VC (Vibration Compensation) was incorporated as an integral part of the opto-electronics design. Priority was given to “dramatically closer” focusing capability, yet size had to remain practical.
Each lens sports a “metal-based” barrel, a brand ring that’s tinted “luminous gold” as well as an SP emblem in the same colour.
The window over the distance scale has been enlarged by 20 percent to maximize visibility and legibility. Font style of the characters and numbers has been changed to enhance legibility.
The shape and sliding torque of the AF/MF change-over and VC On/Off switches have been reconfigured.
The lens is the successor to the AF 18-200 mm f/3.5-6.3 XR Di II LD Aspherical [IF] Macro, which has been one of Tamron’s best-selling lenses since its introduction 10 years ago.
The company says the new lens uses the most modern optical and mechanical design to achieve compactness and high performance.
The lens is the equivalent of 28-310 mm and will focus as close as 0.5 m / 19.7 in.
By incorporating a newly designed autofocus drive module with DC motor-gear train integration, the 18-200 VC also focuses much more quickly and quietly than models with conventional DC motors.
The lens has 16 elements in 14 groups, using an LD (Low Dispersion) lens element to minimize chromatic aberrations and features moisture-resistant construction. The lens also comes with a Zoom Lock feature to prevent unwanted barrel extension when users carry their lens and camera body combinations with the lens pointed toward the ground.
Filter size is 62 mm.
The lens is scheduled to be available later this month, initially for Canon and Nikon mounts, with Sony mount to follow later.
The lens has an optical construction of 18 elements in 13 groups, including an XGM (eXpanded Glass Molded Aspherical) element placed at the front group and several LD (Low Dispersion) glass elements in the system. The company says aberrations such as geometrical distortion and lateral colour are efficiently compensated for enabling the zoom lens to deliver outstanding image quality throughout the entire range from corner to corner.
Tamron’s BBAR (Broad-Band Anti-Reflection) coating is further refined to render uniformity in transmissivity across the critical bandwidths. Coupled with the eBAND coating, ghosting and flare typically observed on ultra-wideangle lenses are efficiently eliminated, Tamron says, resulting in crisper and crystal-clear images.
Because of the large diameter and the prominent convex profile of the front element, it is not practical to deploy a protective filter on the lens, so Tamron has applied a fluorine coating to the front element, which repels water or dirt.
Speed of autofocus and control accuracy are improved, with USD (Ultrasonic Silent Drive) delivering tack-sharp images due to the high torque and fast response speed with the least amount of lag time, says the company, with extremely low acoustic noise. Equipped with a full-time manual focus mechanism, fine focus adjustments are enabled without exiting from the AF mode.
The lens will come with SILKYPIX Developer Studio for Tamron, a RAW image processing software customized for Tamron SP lenses.
Tamron says the lens will be available in Canon, Nikon and Sony mounts, the latter minus VC.
There’s no word as yet on price and availability.
