Adapters Contax 645 lenses to Nikon F-mount cameras. Offers infinity focus and integrated aperture iris. Solid all-metal build for $93 (34% off).
Tip: Enable 'shoot without lens' in camera settings for proper metering.
Best for: Nikon F-mount shooters wanting to use Contax 645 lenses.
The Fotodiox Pro IRIS adapter lets you mount Contax 645 medium format lenses on Nikon F-mount DSLRs. Its all-metal construction ensures a precise, wiggle-free fit, and the integrated aperture iris gives basic light control. Infinity focus is achievable, though you may need to fine-tune with some lenses. Key tradeoffs: no autofocus or electronic aperture - this is a purely manual adapter. The built-in iris helps but causes heavy vignetting when stopped down, so it's best used for creative effect or wide open. Build quality is solid, and the price is a fraction of high-end alternatives. At $93 (34% off the original $140), this is a good entry point for experimenting with Contax glass on Nikon. It's not for pixel-peepers needing perfect iris performance, but for manual shooters seeking versatility, it's a worthy buy.
At $93, you are saving 34% off the original $140.53. The 30-day and 90-day averages are $140.53 and $123.06, respectively, so this is well below recent pricing. It's a strong discount on a niche adapter.
No. This adapter is manual focus only and does not transmit electronic signals between lens and camera.
Yes, the adapter is designed for infinity focus. Some lenses may require a slight adjustment at the infinity mark.
It works with most Nikon F-mount DSLRs, including D7000, D800, D610, D300, D4, D3, D2, D1 series, and many others. Check the full list in the description.
