Zenitar 16mm is another interesting lens, but little much more expensive than the mir,so maybe before i prefer buy a very good 28mm, in future i could think at re sell this mir 20 to buy a zenitar, talkin about price, you say if you could find one at less than 150$ could be interested, maybe this site could be interesting
RUSCAMERA - WELCOME TO OUR STORE i've never try buy something there but it has lot of lenses and camera at good price. I think i will buy the Mir 20 cause seems an opportunity at 75$. Still don't understand if i will have better quality than 18-55. Thanks for answear
