I just received the len yesterday. I use it with Canon EOS50. The pictures were shot at f5.6. I scanned the pictures and resized them, using photoshop.
So far, I really like the len. It is not difficult to use and the effect is so cool! The len is also light and durable.
I just know how to change the aperture and would like to share the method with you. Just simply press the tool on the top edge of the rubber washer and slightly push the rubber away from the len body. Then the rubber will be easily removed. Originally, I tried to push the tool under the rubber but it was quite difficult for me to do in that way so I did try to do it on the top and it worked. By the way, to be safe for the len, I covered the len with a soft cloth before doing.
