Opera series lenses are designed to “perfectly match” recent high-spec full-frame DSLR cameras, says Tokina.
The 50 mm lens adopts a ring-shaped ultrasonic motor for autofocusing. Weather sealing prevents dust and moisture from entering, the company notes.
For the first time in a Tokina lens the Nikon mount model incorporates an electric diaphragm mechanism. The lens also will be available in a Canon mount.
The Tokina Opera 50 mm f/1.4 FF is scheduled for summer availability.
Sigma has unveiled two Art prime lenses, the 70 mm f/2.8 DG Macro and 105 mm f/1.4 DG HSM.
The 70 mm lens, according to the company, is designed to prioritize optical performance, not autofocus speed, delivering “stunning” resolution and “incredible” clarity that “greatly exceed” expectations for a macro lens.
The coreless DC motor further enhances image quality, while an optimized algorithm helps offer extremely smooth autofocus performance for a weightier, high-performance lens.
Sigma says this new lens is the old Macro 70 mm f/2.8 EX DG in a new, updated form.
The lens features an extending, floating, two-group focus mechanism. This configuration minimizes aberration to produce optimal results at any focus distance, says the company. To minimize axial chromatic aberration, the optical system incorporates two FLD glass elements, two SLD glass elements, and one element with a high rate of anomalous partial dispersion and a high index of refraction. In addition, two aspherical lens elements help increase resolution at close shooting distances.
Sigma says this optical system makes possible a razor-sharp in-focus area contrasted with a bokeh area free of colour streaking.
The focus-by-wire system eliminates the direct mechanical connection between the focus ring and the focus drive system. Controlled by a new algorithm, a newly developed coreless DC motor adjusts focus with optimal speed and low noise. Full-time manual focus is available even during autofocus. In addition, the focus ring’s large angle of rotation helps the photographer achieve the extremely precise focusing required for effective macro photography, notes Sigma
The version of this lens compatible with Sony E-mount mirrorless cameras contains the same optical system as for DSLRs. Sigma’s Mount Converter MC-11 is not required, as the lens performs the same functions as the converter, including in-camera image stabilization and in-camera lens aberration correction. In addition, the lens is compatible with Sony’s Continuous AF, which is not addressed by the MC-11.
The Canon mount lens is compatible with the Canon Lens Aberration Correction function. Matching the optical characteristics of the lens, this function performs in-camera corrections of peripheral illumination, chromatic aberrations, distortion, and more, further enhancing image quality. [Sigma does note this function is not available on all Canon camerasm and corrections may vary by Canon camera model.]
The 65 mm Macro Flash Adapter makes the lens compatible with the EM-140 Macro flash.
The lens has a 72 mm filter thread, and weighs 515 g / 18.2 oz.
Pricing and availability for the Sigma 70 mm f/2.8 DG Macro / Art have not yet been announced.
The company says it has designed the lens to offer minimal optical aberration and deliver “incredible” resolution and “stunning” contrast.
The lens is claimed to combine “outstanding” resolution with a beautiful bokeh effect, with great care taken to ensure both the in-focus and out-of-focus areas of the photograph are equally satisfying to the eye.
This lens incorporates 17 optical elements in 12 groups. By including three FLD glass elements, two SLD glass elements, and one aspherical lens element, the optical system minimizes axial chromatic aberration to deliver extremely high resolution along with ample peripheral light volume, says the company.
The area in focus is said to be extremely sharp, while the area out of focus features a beautiful bokeh effect with highly natural colours. The optical system is said to also minimize sagittal coma flare, good for capturing starry skies.
There’s a big chunk of glass on the front of this lens, for a 105 mm filter size. This, notes Sigma, delivers a significantly greater volume of peripheral light than other lenses in its class.
The Sony E-mount version of this lens is compatible with Sony mirrorless cameras and contains the same optical system as the versions for other mounts. The Sogma Mount Converter MC-11 is not required, as the lens performs the same functions as the converter, including in-camera image stabilization and in-camera lens aberration correction. In addition, the lens is compatible with Sony’s Continuous AF.
The Canon mount version of this lens is compatible with the Canon Lens Aberration Correction function. Matching the optical characteristics of the lens, this function performs in-camera corrections of peripheral illumination, chromatic aberrations, distortion.
The lens weighs 1645 g / 58.0 oz.
Pricing and availability for the Sigma 105 mm f/1.4 DG HSM / Art have not been announced.
The lens is claimed to deliver excellent corner-to-corner sharpness throughout the entirety of its zoom range, while also producing beautifully rendered bokeh (background defocus) at all focal lengths.
The 24-105 uses advanced optical design featuring four aspherical lens elements, two of which are high precision AA (advanced aspherical) lenses. There are also three strategically located ED (Extra-low Dispersion) glass elements that work in combination with the aspherical lens elements to minimize chromatic aberration, says Sony.
The lens also has Nano AR coating to minimize flare and ghosting, and utilizes a circular aperture.
Weight is approximately 663 g (23.4 oz), minimum focus distance is 1.25 ft, and the lens includes built-in optical image stabilization.
This new standard zoom lens features a DDSSM (Direct Drive SSM) system that is capable of rapid positioning of the lens’ focus groups with high accuracy and very minimal noise, Sony notes.
The lens also features a customizable focus hold button, a dust and moisture resistant design and a fluorine coating on the front element to help minimize dust, water, oil and other contaminants.
The Sony FE 24-105 mm f/4 G OSS lens is scheduled to ship in November, at a price of about $1,700.
Panasonic has unveiled the Leica DG Vario-Elmarit 50-200 mm f/2.8-4.0 ASPH. lens (equivalent: 100-400 mm), with Nano Surface Coating technology to minimize ghosts and flaring, plus a rugged, dust/splash-proof design that is freeze-proof to -10F.
The Power O.I.S. (Optical Image Stabilizer) compensates for hand-shake movement. The lens works with Dual I.S. (Image Stabilizer) and Dual.I.S.2 when mounted on compliant Lumix cameras.
Comprising 21 elements in 15 groups, the lens system features two UED (Ultra Extra-low Dispersion) lenses, two ED (Extra-low Dispersion) lenses and two aspherical lenses.
The sensor drive at max. 240 fps takes full advantage of cameras with high-speed, high-precision Contrast AF for video recording performance, and an inner focus drive system ensures smooth, silent operation. A micro-step drive system in the aperture control helps the camera smoothly catch up to brightness changes when zooming or panning, sats the company. The optical design is said to provide exceptional barycentric stability to minimize image shifts during zooming.
The Leica DG Vario-Elmarit 50-200 mm will be available at the end of June.
Tokina has announced the Tokina FíRIN 20 mm f/2 FE AF lens, the second prime lens in the company’s premium lens series for mirrorless cameras. It’s the autofocus version of the existing Fírin 20 mm f/2 FE super wide angle lens for full-frame Sony E-mount, with the same optical design as in the manual focus model.
The optical design uses two aspherical elements and three lenses molded from Super-low Dispersion glass to significantly reduce any type of aberration including spherical aberration, distortion and chromatic aberration while assuring high resolution and what Tokina calls “stunning” performance even at wide open aperture.
For the AF drive system the lens uses a quick responsive and silent ring-shaped ultrasonic motor. Tokina says the lens is fully compatible with Fast Hybrid AF system and all AF function settings, providing the same AF performance as with common E-mount AF lenses. Fine manual focus adjustment is also possible.
The Tokina FíRIN 20 mm f/2 FE AF is tentatively scheduled for late May availability.
Tamron is launching the 70-210 mm f/4 Di VC USD lens, a compact telephoto zoom for full-frame DSLRs. The company says the lens provides “superb” optical performance throughout the entire zoom range and features a maximum magnification ratio of 1:3.1.
The design includes an internal zoom mechanism that provides solid mechanical construction and stable, reliable operation, notes the company.
The lens also employs a Dual MPU (Micro-Processing Unit) design, which enables high-speed and high-accuracy AF performance as well as powerful VC (Vibration Compensation) image stabilization.
The zoom is equipped with fluorine coating and moisture-resistant construction.
The lens is said to achieve superb optical performance with high contrast and resolution. The optical construction (20 elements in 14 groups) uses three LD (Low Dispersion) lens elements to effectively compensate for axial and transverse chromatic aberrations.
Compared to large aperture telephoto zoom lenses, this new model is lighter with a weight of 850 g (30.3 oz) and is more compact with a total length of 174 mm (6.8 in).
Nikon and Canon mount version of the Tamron 70-210 mm f/4 Di VC USD lens will be available in April.
The XC15-45 mm lens will be available March 15 for $379.99.
Leica has announced the first two lenses in a new line of high-performance Summicron-SL lenses for the Leica SL system – the APO-Summicron-SL 75 mm f/2 ASPH. and the APO-Summicron-SL 90 mm f/2 ASPH. Both lenses seamlessly work with the SL-System’s autofocus and, as with all SL lenses, have been designed and constructed in Germany.
Leica says both the construction and design of the new lens line represent the continuing innovation in the development of lenses for the Leica SL-System. State-of-the-art, extremely precise manufacturing methods and measuring technologies were developed specifically for the production of these lenses, notes the company. The results are reflected not only in the more compact dimensions and considerably lower weight of the lenses, allowing for greater portability, but also in excellent imaging performance, it says.
The lenses feature a new, faster autofocus system, as well as a considerably shorter close focusing limit for tight portraits. The autofocus drive of all Summicron-SL lenses employs stepping motors with DSD (Dual Syncro Drive). Thanks to this advanced focusing drive, Leica says the entire focusing range can be fully travelled in about 250 milliseconds.
Meticulous attention was paid to the prevention of stray light and reflections in the construction of the APO-Summicron-SL lenses, the company notes. Together with optimizing the optical and mechanical design, the application of high-quality coatings to each lens surface reduces unavoidable reflections to an absolute minimum.
To reduce chromatic aberration to a hardly perceptible minimum, both new Summicron-SL lenses are Apochromatic, or in short, APO, corrected, allowing photographers to capture photos in high contrast situations without a distracting purple or green outline along backlit subjects. Most of the 11 elements of the optical system, one of which is aspherical, feature anomalous partial dispersion and are manufactured from sensitive and specially formulated, high-quality glass.
The APO-Summicron-SL 75 mm f/2 ASPH. and the APO-Summicron-SL 90 mm f/2 ASPH. will be available in February.
Take note: Leica says two more lenses will be available in the second half of 2018, the Summicron-SL 35 mm f/2 ASPH. and APO-Summicron-SL 50 mm f/2 ASPH.
Definitely not your average snapshooter’s lens! Nikon’s AF-S Nikkor 180-400 mm f/4E TC1.4 FL ED VR has a name which begs explanation. This pro level FX-format lens has been updated not only with the newest lens technologies and an advanced optical formula to enhance performance and reduce weight, but it also features the company’s first ever built-in teleconverter. Ah, now the TC1.4 part of the nomenclature makes sense.
The lens delivers a constant f/4 aperture and the built-in 1.4X teleconverter allows photographers to seamlessly swap to a 252-560 mm. The teleconverter is engaged at the flick of a switch, and is easily operated with a single finger while looking through the viewfinder. When used on DX-format DSLRs, the focal length is the equivalent of 270-600 mm (378-840 mm with the teleconverter engaged).
The lens features an electromagnetic diaphragm, helping to create smooth and consistent exposures while shooting high-speed bursts of images, Nikon explains. What’s more, the AF tracking algorithm controlling the motor drive has been enhanced to increase tracking performance of fast moving subjects. When using
cameras equipped with Nikon’s advanced 153-point AF system (D5, D500, D850), the outer row of AF points are activated as cross-type sensors to significantly enhance the AF coverage throughout the frame. This feature will be available with a firmware upgrade for the D5, D850 and D500.
The lens now uses a fluorite element, which contributes to improved balance while minimizing weight. To further enhance handling and agility, the lens has adopted a new ball-bearing tripod collar ring to create a seamless transition from shooting horizontal to vertical composition. The VR mechanism offers a normal and sports mode, with up to four stops of compensation to help create sharp images, even when handheld.
The lens construction includes the use of durable magnesium alloy for weight reduction, while the lens is also sealed against dust and moisture. A fluorine coating is also used to help repel water droplets and dirt.
The optical formula of the lens uses eight Extra Low Dispersion (ED) elements, doubling the amount of ED elements used by its predecessor, the Nikkor 200-400mm. Nikon says the optics help to provide extremely sharp and detailed images and 4K video. Nikon’s Nano Crystal Coat is used to effectively suppress instances of ghosting and flare, says the company.
The AF-S Nikkor 180-400 mm f/4E TC1.4 FL ED VR will be available in March for a suggested retail price of $15,549.95.
The lens measures 2.75 x 3.5 inches and weighs 11.5 oz.
It is the equivalent of 27-202.5 mm in full frame.
The company says the lens produces “outstanding” corner-to-corner sharpness throughout the entire zoom range thanks to its design featuring one aspherical lens and two extra-low dispersion glass elements that minimize aberrations. Maximum magnification ratio is 0.29x and minimum focus distance is 1.48 ft.
The lens is said to offer fast, precise, quiet AF performance thanks to a linear motor.
The Sony E 18-135 mm f/3.5-5.6 OSS APS-C lens will ship in February and will be sold for about $780.
