The lens comes in excellent condition with just light signs of previous use. The barrel looks good and well cared for. The focus is smooth and aperture is working like intended. The glass looks excellent with no remarks. The back retaining ring was professionally shaved for mirror clearance with full-frame DSLR cameras like EOS 5D, but ofcourse all still perfectly usable on Leica R cameras as well. A hard to find fast and wide lens we can rate 8.5 out of 10.
