Adapt old Mamiya NC1000 / CS lenses to your modern EOS DSLR camera while retaining inifinity focus and aperture function.

Best Practices & Caveats
Follow these rules and you can safely use your CS glass on your modern EOS camera.

-When installing or removing the adapter the CS lens aperture ring must be in the f/16 setting.

-Install the adapter to the CS lens first, then seat the lens to your DSLR like any other Canon EF lens. This adapter works like the Mamiya NC1000 / CS P-mount for M42 Screw lenses.

-this adapter utlizes a FRICTION-FIT-ONLY. This means when focusing and adjusting aperture you must secure the lens barrel with one hand, using the other hand to rotate the mechanisms to ensure the lens does not rotate and fall out.

-While installed Do not move the aperture ring to the "Auto" positon (the orange button). Doing so may result in damage to the lens.

-When not in use leave the lens in the f/16 position to relax tension on the lens mechanisms, or just remove the adapter entirely.

-Although Mamiya ZE lenses are similar to CS lenses, this adapter is NOT compatible with ZE lenses. The mechanical parts on ZE lenses are too long and in the way if you try to use this adapter. Best case, it wont fit -- Worst case, broken DSLR -- DONT TRY IT

Here are the legal bits...

On 2011 I got the CS lens 50 f/1:1.4 and MC lens 70-150 zoom f/1:3.5 include with the NC1000 body, had no idea how to attach these lens to my T2i EOS body until I saw this website. I just put an order, black color, hope they can ship it sooner (can't wait!). I will post the photo result here.

True that! its been more than a month since Im using the adaptor and i have to say its great. Here its a example photo using a Canon 5D Mkii and a Mamiya/Sekor 50mm f1.4: About the tightness its just the initial use, after a long time of use it gets softer but not enought to fall of the camera for sure. Im in love with how it works, and yes, a good blow do the trick.

Quote: the only issue, its that the adapter fits really tight in to the body of the camera You're right, it is a tight fit. It was a balancing act between being too tight and too loose. Too lose and the lens could fall out while focusing, too tight and its, well, too tight. Since the adapter is made of plastic, it cant damage the bayonet on the camera. In the very worst case there could be some tiny plastic rubbings left behind when removing the lens. 3 seconds with air blower is all that's necessary to eliminate dust and other particulates -- most photographers do this when changing lenses anyway.

The adapter just arrived, I'm really happy with the results, I already tested 3 different lenses on my Canon 5D Mark II: a 50mm f2.0 a 28mm f2.8 and a 135mm f2.8. Everything works flawless with the lens, the only issue, its that the adapter fits really tight in to the body of the camera, is not really a problem, but it feels weird to force it. Excellent product! Totally recommended! Thanks for making this!
