First try with a Jupiter 9

I just got this lens from Moscow - it's a new copy. 85mm f2 - just a little soft wide open and nicely sharp fro 2.8 on. I shot in A mode, but metering is off by about 3 stops (over) - don't know what I'm doing wrong - any advice is appreciated.

...also this looks yellow/green from Flickr, not so on my monitor.
