This auto focus circular fisheye lens has an angle of view of 180 degrees in all directions. It is exclusively designed for digital SLR cameras with the APS-C size image sensor. When used in conjunction with digital SLRs with APS-C size image sensors, it produces circular image within the frame. The F2.8 large aperture value produces a bright image in the viewfinder and allows photographers to take pictures in low light conditions, making it an ideal lens for Astrophotography and Aurora photography. Due to the quantifiable angle/area relationship it produces, this lens can be used for scientific and arts applications such as solid angle measurements of cloud distribution over the sky or vegetation distribution of the forest. The minimum focusing distance of 13.5cm/5.3inch and maximum magnification of 1:6 make it particularly useful for close-up photography. SLD??Special Low Dispersion??glass provides effective compensation of chromatic aberration. Sigma??s Super Multi-Layer Coating minimizes flare and ghosting. It is equipped with an inner focusing system that creates high definition and good image quality over the whole frame. The HSM (Hyper Sonic Motor) ensures fast and quiet autofocusing and allows full-time manual focus override by rotation of the focus ring.
Lensbabies selective focus SLR camera lenses bring one area of your photo into sharp focus, with that sweet spot surrounded by graduated blur. You can move the sweet spot to any part of your photo by bending the flexible lens tubing.
Sigma 20mm f1.8 EX DG Aspherical RF is one of several EX Series lenses. It is the first 20mm Super wide-angle lens in the world with a large aperture of F1.8 and angle of view 94.5°. It has Macro focusing capability with a minimum focusing distance of 20cm/7.9inches (reproduction ratio 1:4). The iris diaphragm has 9 diaphragm blades to obtain beautiful out of focus image. It incorporates an aspherical lens element in the front as well as rear lens groups, to minimize distortion, spherical aberration and astigmatism. The lens has non-vignetting optical construction, in order to obtain adequate peripheral brightness with open aperture. This is especially desirable for digital cameras. The lens incorporates a rear focus system eliminating front lens rotation, thus allowing the use of a Perfect Hood and easy use of polarizing filters. The lens also incorporates dual-focus mechanism. It is easy to hold the lens, since the focusing ring does not rotate during auto-focus, yet it provides adequate focusing torque of the focusing ring during manual focusing of the lens. The lens materials used in this lens are lead and arsenic free ecological glass.
Designed exclusively for Nikon DX-format SLR cameras, this 18-55mm lens approximates the picture angle performance of a 27-82.5mm lens in the 35mm format, ensuring superb versatility in a wide variety of shooting situations. The lens offers such features as a Silent Wave Motor (SWM) with a compact rod-type design that provides fast, ultra-quiet autofocusing; an ED glass element that minimizes chromatic aberration and produces a superior optical performance; a hybrid aspherical element that delivers high resolution and contrast; and a seven-blade rounded diaphragm that produces more natural out-of-focus highlights. The focus mode switch, meanwhile, makes it a breeze to switch quickly between autofocus (A) and manual (M) focus. Finally, the lens's Super Integrated Coating minimizes ghosting and flare to provide an even higher contrast and more vivid images, even in challenging light conditions. All Nikon lenses carry a five-year warranty.

Lens filters are translucent pieces of glass placed in front of a camera lens to alter or adjust the light entering the camera, and more importantly to protect the camera lens. Lens filters improve photographs by giving you control over light and allowing you to emphasize the features of a scene that you consider most important. This filter kit is a combination of the three essential filters no photographer should be without
