This telephoto macro lens is capable of focusing to life-size (1X) without attachments. Although it replaces the EF 100mm f/2.8 macro lens, it is a completely new design. It incorporates a ring-type USM giving quiet, high-speed autofocus. The full-time mechanical manual focus gives very smooth manual focusing. For the first time in a 1X focusing telephoto macro lens, inner focusing is used.The lens length remains constant and a long working distance of 149mm makes worrying about getting too close to the subject unnecessary. Also, during focusing the front ring does not rotate making use of front-mounting accessories like macro ring lites simple and effective. "Three-group floating" focusing construction uses three independently moving groups, which holds focusing-related changes of aberrations to a minimum giving excellent image quality all the way from infinity to life size.

The ZUIKO DIGITAL ED50mm f2.0 Macro is a dedicated lens for macro photography. The 2.0 maximum aperture makes it excellent for available-light shooting while the attachment of macro flash systems is also possible. It includes an ED lens element for crisp, colorful images.

Two SLD glass elements are especially effective in the compensation of magnification chromatic aberration.Glass mold aspherical lens at rear group of lens reduces color aberration and provides high-quality image results. From 40cm (15.7'') minimum focusing distance to infinity, this lens creates very sharp images with high contrast.The HSM models provide quiet high-speed auto-focus shooting, as well as full-time manual focus. Large Maximum Aperture of F1.4 can perform superbly in a great range of applications, including snapshots, portraiture, indoor shooting and landscape photography.

A fisheye lens is a wide-angle lens that takes in an extremely wide angle of view. The Nikon 2148 AF DX Fisheye-NIKKOR 10.5mm f/2.8G ED lens was designed exclusively for NIKON digital SLR cameras that feature NIKON's DX Format Sensor. The AF DX Fisheye-Nikkor 10.5mm f/2.8G ED lens significantly expands NIKON's DX-Nikkor category of interchangeable lenses. Go beyond wide angle with this DX series lens for your Nikon DSLR. The actual focal length of 10.5mm is equivalent to that of about 16mm on a 35mm-film camera. 16mm is considered the borderline from ultrawide angle to fisheye. Unlike older fisheye lenses that cut-off the corners, this fisheye lens fills the entire frame with a useful image. Nikon DSLR owners now can enjoy wider angle shots of landscapes, skylines, and astronomical views of the night sky with the Nikon AF DX Fisheye-NIKKOR 10.5mm f/2.8G ED lens. This is the wide-angle lens you've been missing. Now is your opportunity to pick one up. Extra-low Dispersion (ED) glass element minimizes chromatic aberration. Design enables a combination of wider angle of view with optical characteristics that are optimized for Nikon digital SLR camera sensors. Nikon D-type design provides precise distance information for flash and ambient light exposure processes. Rounded diaphragm makes out-of-focus elements appear more natural. G-type DX NIKKOR is designed exclusively for use with Nikon digital SLR models. Built-in flower-type lens hood Includes CL-0715 soft case, lens cover, rear cap For Nikon DSLR camera with a DX mount / Also compatible with FX series in DX crop mode

Sigma launched first standard 50mm Macro lens in 1990. This was succeeded by the 50mm F2.8 EX Macro in 1998 which proved even more popular with photographers, benefiting from improved build and optical quality. The advent of digital SLRs requires optimum lens performance and therefore the very latest optical technology has been incorporated in the production of the New Macro 50mm F2.8 EX DG. This ideal standard lens sets the benchmark for digital SLR cameras. The new advanced lens design corrects various aberrations. This macro lens is specially coated to get the best color balance whilst cutting down ghost caused by reflections from the digital image sensor. This lens provides the utmost correction against lateral chromatic aberration which is a serious problem for digital SLR cameras.
