"Whether you're shooting digitally or on film, Fotodiox offers the world's largest selection of lens adapters. Mix camera/lens platforms or reinvigorate vintage glass; Fotodiox has hundreds of ways to mount lenses onto your DSLR or SLR camera. Our adapters deliver infinity focus, manual aperture control, and a sturdy build for lasting quality. 
M42 Lens Compatibility Note: 
This adapter is ‘Type 2’ which means it works with M42 lenses that have no aperture control from the aperture ring and require a pin on the rear of lens to be depressed in order to engage the aperture ring.

Please Note: 
; Due to the Nikon F-mount focal flange being longer than the M42 mount, infinity focus will not be possible. 
; Lens orientation will vary from lens to lens. 
; This is a manual adapter, so lens functions that rely on electronic communication with the camera body (autofocus, AE metering, image stabilization, etc.) will be disrupted. 
; We state “infinity focus allowed†because our adapters are designed to be universal which can prevent some lenses from focusing to infinity at the infinity mark. 
; Set your camera to “Manual’ or ‘Aperture Priority’ for metering. If camera does not release be sure to enable ‘shoot without lens’ in camera settings. 
; All pictures are for illustration purposes only. Actual product may vary slightly due to ongoing improvements in design."
