The quality performance is ensured by the inclusion of two UD elements (ultra-low dispersion) and a floating lens group into the lens’s optical construction. They help avoid chromatic aberration while the Super Spectra coatings minimizes flare and ghost.

The lens benefits from Canon proprietary Optical Image Stabilizer (IS) technology that prevents from blurring when shooting at shutter speeds 4 stops slower than it would be otherwise possible and thus helps achieve sharp images in unfavorable lighting conditions.

A circular aperture comprised of 8 diaphragm blades delivers a pleasant effect of bokeh, which is a subject-background separation by blurring background areas.

Autofocus is driven by to a ring-type USM AF motor that shows quiet yet fast operation. It provides for precise focusing as well thanks to an independent lens CPU. The lens also provides for a full time manual focus override in AF mode.

The lens’s build quality is worth mentioning. The body is protected from environmental influence while its Fluorine Coating makes it easier to clean the lens.

Nikon launches the new AF-S NIKKOR 24-120mm f/4G ED VR lens that would suit both FX and DX photographers. Its focal length range ensures its versatility and makes it possible to use it for different types of photography.

The lens’s f/4 constant aperture coupled with the new VRII shake reduction system extends the possibility of handheld shooting in low light. It allows using shutter speed four stops slower than it would be otherwise possible, which helps the lens deliver bright as well as sharp imaged even in toughest lighting conditions.

There’re 17 elements in 13 groups in the lens’s optical construction. Two ED and three aspherical elements help minimize aberrations while Nano Crystal coating eliminates ghost and flare.

The lens’s 9 aperture blades close to a rounded aperture, which produces gentle bokeh, the effect of blurring in background and foreground areas.

The AF-S NIKKOR 24-120mm f/4G ED VR incorporates a Silent Wave Motor (SWM) that allows for precise autofocus performance as well as the ability to use override autofocus by manual one  in M/A mode. It also delivers smooth and noiseless operation.

This standard zoom lens makes the perfect travel companion thanks to its compact design and the use of magnesium and Super Engineering Plastic elements in its construction. The switches are sealed with rubber that’s why the lens can resist dust and moisture.

The lens succeeds and replaces a famous and highly valued AF NIKKOR 85mm f/1.4D IF model. It inherits its major features while leaving space to innovations.

The AF-S NIKKOR 85mm f/1.4G includes 10 elements in 9 groups in its optical construction, the elements being covered with the anti-reflection Nano Crystal coat for excellent ghost and flare reduction. As a result, the images created with this lens are clear, crisp and rich in contrast.

The bright aperture extends the possibility of handheld shooting in low-light while providing for superb separation of your subject and background/ foreground. Moreover, the lens creates a beautiful bokeh ( blurring of out-of-focus elements) thanks to its 9-blade diaphragm.

The lens is equipped with a Silent Wave Motor (SWM) to quiet and accurate autofocus operation. The operation of manual focus is smooth as well.

The lens body is made from magnesium alloy and is sealed against moisture and dust to provide for safe shooting in tough situations e.g. foul weather.

It delivers extremely wide 180º field of view on them.

When used with cameras featuring APS-C or APS-H sensors the lens shows more moderate field of view coupled with vignetting, but there’re ‘C’ and ‘H’ markings on the lens body, which allows locking zoom at a value that provides for vignette-free shooting for each sensor.

The lens is promised to deliver superb image quality thanks to its advanced optical construction. It combines 14 elements in 11 groups and features 1 aspherical and 1 Ultra-low Dispersion (UD) element to minimize aberrations and ensure contrasty pictures with true-to-life colors. All lens elements are covered with the Super Spectra Coating to reduce ghost and flare. In addition, the front lens element features the SubWavelength Structure Coating on its inner surface to improve flare reduction.

The EF 8-15mm f/4L Fisheye USM incorporates a ring-type ultrasonic motor (USM) that focuses quickly and precisely as well as enables full-time manual focus so that you can change focus by moving the ring even when AF is active.

The lens is housed into a dust- and water-resistant body made from high-quality materials, which is typical of all new L-series models. Moreover, front and rear lens elements are coated with fluorine to protect them from water, dust and make it easier to clean the lens.

Carl Zeiss announces the ZF.2 version of its 25mm f/2.8 wide angle fixed-focal lens for Nikon F mount. Now this legendary lens comes with an electronic interface and delivers 25mm field of view on a full-frame camera and 38mm field of view an a sub-frame DSLR with 15x crop factor.

The electronic interface means that though it is a manual-focus lens it supports automatic exposure modes like Program, Aperture and Shutter priority modes. Moreover, you don’t have to manually set the focal length and speed data in the cameras as now all the lens-related parameters are passed to the camera and included into EXIF.

The lens would be ideal for photo enthusiasts who want to get creative, high-quality images while enjoying comfort of using automatic exposure controls. It can be used for nature photography due to its small closest focusing distance (0.17m).
