This is a very impressive lens!
The aluminium body keeps the lens light. When I attached the Jupiter-11 to my Zorki-4 I didn't have that weighty, unbalanced, cumbersome feel I've experienced with other telephoto lenses.
The lens is sharp as a pin and produces crisp, constrasty images. Both the focus and the aperture adjustment were very smooth and easy. The lens was used but well cared for with only a few very minor scuff marks. All in all, a very nice telephoto lens for your FED or Zorki!
Yuri's frequent order status updates, speedy shipping and care with packing the lens is always very much appreciated. Rating: [5 of 5 Stars!]
