This is the lens on my 35mm SLR. Taken holding the lens in my hand backward onto the camera body and held the aperture open with a piece of string so it was on its maximum(f5.6?) Got the focus by moving the whole camera backwards and forwards. Th Exif file shows a focal length of 0 as there is no lens fixed to the body. I now have a reversing ring on order which should make it easier next time.The numbers are 2mm high. Took it in low-res .jpg as I was experimenting and it's SOOC.
