Excellent! It works perfectly on the Canon 6D too!
Shipping was not fast, but the product is good and works well on my Canon 6D. It also allows me to use lenses with infinity focus. The chip works well and, after programming it, I have both the EXIF data for aperture and lens length, which in this case is a Helios 44-2. With programming and calibration, I always get the correct focus. Recommended product.
I bought one for my canon 6d + helios 44-2 / takumar 50mm. the adaptor is too thick or the chip is out of calibration. autofocus confirmation is heavily back focus. unfortunately even with micro adjustment with the camera it is not enough. there was no benefit in paying a lot more money for a chipped adaptor for me. this one for sale is too thick
Satisfied, highly recommend
