35 mm
Sigma 35 mm f/1.4 DG HSM
The Sigma 35 mm f/1.4 DG HSM lens is the first offering from the company’s new Art line, one of three new lines that also includes Contemporary and Sports categories.
As part of the Art line, the new lens has been designed with a focus on optical performance and artistic expression for users who value a creative, dramatic outcome above compactness and multi- function.
The f/1.4 aperture produces a beautiful bokeh effect; the large aperture also makes the lens particularly suited for HD video.
Lens construction is 13 elements in 11 groups.
The lens incorporates an “F” Low Dispersion (FLD) glass element, with performance equal to fluorite, and Special Low Dispersion (SLD) glass elements to correct chromatic aberrations and achieve ultra-high image quality through the entire focusing range.
Optimum alignment of aspheric lenses corrects astigmatism and field curvature to ensure high resolution, even in peripheral areas.
A floating inner focusing system compensates for astigmatic and spherical aberrations and provides extremely high optical performance for close-up photos, says the company.
The advanced optical design, combined with Sigma’s Super Multi-Layer Coating, reduces flare and ghosting and provides sharp, high-contrast images, even in backlit conditions.
The lens incorporates a Hyper Sonic Motor (HSM) with an enhanced algorithm to provide smooth, quiet, high-speed autofocus with full-time manual focus override.
A specially treated brass bayonet mount provides greater strength, precision, and durability, notes Sigma.
The lens is compatible with Sigma’s new USB Dock and Optimization Pro software that let you update lens firmware and adjust parameters such as focus.
Minimum focusing distance is 30 cm (11.8 inches). Weight is 665 g (23.5 oz).
The Sigma 35 mm f/1.4 DG HSM lens has a suggested retail price of $999.95 and will be available in December for Canon and Sigma mounts. Nikon, Pentax, and Sony mounts will follow in 2013.
Two Canon pro lenses
Canon has two new EF lenses, the EF 24-70 mm f/4L IS USM and EF 35 mm f/2 IS USM.
The EF 24-70 mm has macro shooting capabilities at the telephoto end and the EF 35 mm adds Canon’s proprietary Image Stabilization (IS).
Featuring dynamic L-series optical performance in a compact, lightweight and durable design, the new 24-70 mm lens features a constant maximum aperture of f/4 throughout the entire zoom range, with 15 lens elements in 12 groups including two aspherical and two UD lens elements and a 9-blade circular aperture diaphragm.
Macro at the telephoto end delivers a 0.2 m/7.9-inch minimum focusing distance.
It has Canon’s Hybrid IS system, with up to four stops of stabilization.
The macro feature can be engaged through a switch on the lens barrel.
In addition, the lens features inner focusing and a ring-type Ultrasonic Motor (USM) for quiet, fast autofocus, and has full-time mechanical manual focus that’s enabled even during AF operation.
Compact at only 93 mm in length, with excellent dust and water resistance, the lens has a fluorine coating on the front and rear elements for easy maintenance and cleaning.
The EF 24–70 mm f/4L IS USM lens is expected to be available in December for an approximate retail price of $1,649.99.
The successor to Canon’s EF 35 mm f/2, the EF 35 mm f/2 IS USM lens is a compact and lightweight wide-angle prime lens. The optics and mechanical workings are designed to improve image quality in the lens’s periphery and provide faster and quieter AF than its predecessor, as well as Optical IS and optional full-time manual focus, all in a durable lens body with a high-grade design.
Featuring a circular aperture diaphragm and lens coatings optimized for minimal ghosting and flare, the EF 35 mm is said to achieves beautiful, soft backgrounds and amazing image quality.
The EF 35 mm f/2 IS USM lens is expected to be available in December for an approximate retail price of $929.99.
Three Sigma lenses
Sigma has announced three new lenses at Photokina:
The 17-70 mm f/2.8-4 DC OS Macro is designed for cameras with an APS-C sensor and is the equivalent of 25.5-105 mm.
An upgrade to its predecessor, released in late 2009, this general purpose lens offers a new design and a more compact build.
The 35 mm f/1.4 DG HSM is an alternative to the more conventional 50 mm.
This lens’ axial chromatic aberration is minimized, which renders a smooth out-of-focus image. At low apertures, it can perform like a wide-angle lens; when opened up to f/1.4 it will provide background bokeh and make the subject pop like a mid-range telephoto lens.
The 120-300 mm F2.8 DG OS HSM is an update of the lens released in early 2011, with redesigned mechanics and performance.
This lens is dust and moisture resistant, and allows users to adjust the focus speed and the focus limiter via a button on the lens.
Sony lenses
Sony has new lenses for both its DSLRs and its E-mount NEX lineup.
For DSLRs, there’s the new 300 mm f/2.8 G SSM II. Designed for sports and wildlife applications, this bright super-telephoto offers a significantly improved optical design and handling compared with its predecessor, says the company.
The Sony-developed Nano AR Coating is said to assure flawless still images and HD video with reduced flare and ghosting, offering enhanced contrast.
A new LSI drive circuit offers faster, more accurate autofocus with enhanced subject tracking.
The new lens is also dust- and moisture-resistant.
A new wide-aperture Carl Zeiss A-mount prime lens is now under development, says Sony.
Optimized for superb results with the new alpha 99 DSLR’s full-frame image sensor, the Planar T* 50 mm f/1.4 ZA SSM will be available next spring.
The 300 mm lens will be available in November.
E-mount lenses
Sony has introduced three new lenses for its E-mount line of interchangeable lens cameras.
The light, compact 16-50 mm f/3.5-5.6 powered zoom measures only 29.9 mm thick (when fully retracted) and contains built-in Optical SteadyShot image stabilization.
It features a dual-function ring that controls both power zoom and manual focus, depending on the camera’s focus mode. With the camera set to AF the control ring adjusts smooth, high-speed zoom with small hand movements. With the camera in MF mode, the ring controls manual focus. A smooth power zoom dial makes the lens particularly useful for shooting video, Sony suggests.
A wide aperture 35 mm f/1.8 lens has built-in Optical SteadyShot image stabilization. Sony says it offers excellent optical sharpness, clarity, and background defocus in both still images and HD video.
The 10-18 mmf/4.0 super-wide zoom has built-in Optical SteadyShot image stabilization. The lens features super ED (Extra-low Dispersion) glass which reduces colour aberration.
