I just got a new to me 50mm SEL. I messed around with it a bit last night, and love it. The shade that comes with this lens is huge. I am not sure I would ever use it. Looking into my junk drawer, I noticed one of the "flower pedel" shades that was left over from a previous lens. It fits perfectly! I noticed the 50mm has a firmware update. How do I check to see if this has been done? Also, how does one update the firmware on a lens? This lens could quickly become a favorite lens.
