    Hello Everyone!
    I wanted to have a play with these cheap lenses fully manual, to test my ability to focus with manual only.
    Just bought one of these 50mm RF mount 0.95.

    The issue is that the full frame is capturing the lens (no hood!)

    I have remove all lens setting in the camera. The lens is supposed to work on RF mounts and full frames and is failing on my EOS R (i can't test my r5 as it is travelling).

    Any tips or is this lens faulty?

    this seems like a lot of barrell in the image for an RF lens. I think it may be defective.
    I don't see examples of that issue with other image/video online. This seems its more than some vignetting that can be corrected in camera, but I would try another copy.
