The KIPON C645-NIK adapter mounts Contax 645 series lenses on Nikon F mount SLR and DSLR camera bodies to take advantage of the best of both manufacturers. Your favorite Contax lenses easily fit, lock securely and perform just like they were Nikon lenses. There areno interfering glass elements to spoil the excellent Contax Zeiss optics. These outstanding lenses have plenty of resolution to satisfy DSLR high resolution sensor's pixel size even at widest open aperture. Zeiss is famous for contrast, flare resistance, colorsaturation and bokeh and is in a class of its own compared to the best Nikon glass.
The lens adapter has a smooth adjustable aperture ring to precisely set the iris blades at any point on the engraved collar. Even though no camera to lens automation or link exists within the adapter, the Nikon F mount SLR can provide aperture priority or manual shooting modes, as well as stop-down metering, for exposure control. While infinity focus is retained in this design, only manual focusing is possible.

KIPON offers a full line of camera lens adapters including macro adapters, electronic adapters, adapters with integrated glass, optical focal reduction adapters, adapters with built in aperture control, tilt/shift adapters, tilt adapters, and shift adapters. All KIPON adapters undergo the CNC turning center procedure during manufacturing to provide photographers with only the utmost precision and quality.
