Dirty inner lens unit
The master made me a Canon EF 24-70 f / 2, 8L lens. Replaced the torn diaphragm loop. I did it, everything is fine, but I'm sorry, he rubbed the inner lenses so roughly, after leaving the fat-and-fat prints on the inner windows, that if you look closely at the dirty stains in reflected light. They can not be reached without dismantling the lens. And as if they do not affect the final result of the image. I think that maybe there should be a bit of a drop in contrast, but I do not remember how this picture was shot earlier and can not be compared with the current picture. Do you think I should not bathe in this or give it back to cleaning the windows? Extra time to disassemble and collect will not benefit the lens, such as the best enemy of the good, or else something definitive will break something.
