it's true that its a bit soft wide open but thats exactly what I like about it for portrait.
Mine is bit rattly at the lock for the bayonet.
a bargain at today´s cheap prices. My copy needs to be stopped down to f5.6 for optimum sharpness, wide open it´s quite a bit softer (unlike my FDn 200mm f4). The built in lens hood is too short, but at least it´s always there, and is certainly better than nothing. I add a longer hood over the top of it when necessary. Reasonably lightweight and compact, typical FDn build.
I bought this lens to complement the Panasonic Lumix 45-200 for situations where I need a faster lens. It does an admirable job at concerts and the size is just bearable for hand-holding on a small camera. On my Canon A-1 it's quite good as well for portraits. The coating and the built-in lens hood make it resistant to flare. The sharpness is excellent for such an inexpensive item.
I bought this to complement my 85 on the long side, since I'm not using the 200 mm that much. Great value, and a solid performer. Also, it's really comact for those street scenes were you want to be discreet...
