The product is simple and its quality is good, but only good for a restricted use unlike my former expectation. Good for EFS lenses and APS-C Canon cameras. I intended to use this with my Canon 1D, but failed. Not for every focal length, but especially for telephoto lenses. With 55-250 IS STM, it looks useful, but with 50mm, it does not work properly. It transfers the aperture and focal length of the lens as converted just as the angle of view and the amount of light is changed, but I wish it had another option to pass the info without modified so that there might be no compatibility issue among bodies and lenses.

Image quality on crop sensor (canon 80d,canon sl2) is unacceptable.lack of sharpness. on full frame canon 5d mark II ,images are only marginally acceptable as long as no cropping is done.Results were the same on a variety of canon lenses and 1 tamron 150-600 lens.
