Well the main feature I'd like is for it to work all the time. The one I have now is actually great for me but it works when it wants to, and one of the elements in the lens is damaged. The damage in the lens doesn't effect the reading at all, but it's rather annoying to have in your line of sight. Also, the meter acts funny in low light situations. Oh, and the $200 was a mistake...I meant to say $300.
