This lens. That is, as I write the piece that I got to hand is excellent. I was very surprised when the transmission quality of light. I use it while reducing the bayonet on the M42 Canon Canon EOS 600D. This camera has the + mi dense sensor and is commonly seen even the smallest deviation aberration. When 70-210 mm Cosina is no indication. Even better results bear as Canon L lenses. It's incredibly since I bought it for 50USD.
although I have no objection urine result of this lens filter skylight more precise picture.
I would not trade him for even Canon L lens. I do not need autofocus
