if you read all these bloated opinions here, you dare almost no longer to draw up a not so profound opinion. Although I must admit that I do not understand many of these reviews. I'll keep out of the time of Nikon F2, Contax RTS, Leica SL2 etc ..... with Kodak and Ilford Vericolor- movies. I handle my house against a "reference roof" with nice sharp tiles ... with nem horizon ... a normal lit living room ..... and can with aperture and shutter speeds. You get here for about 165 (new), and around 100 in stock exchanges (used) a class fixed focal length (as well as with the 50s 1.8), which is thoroughly recommended. The lens is sharp crack, the autofocus fits well and quickly ..... What I want / you more?!?! Each Hobbyknipser ... even with very high demands is well served here ... EVERYONE !!! Ok you can not splurge verbally, but you have a great lens!
