Firm Eyes

I'm not sure many people would get that the symbol is representing a focus meter in the viewfinder unless you're a photographer. That's fine for people to not necessarily fully understand what a symbol is, but a logo symbol should always be unique and eye-catching. So, in my opinion a box with four little boxes around it is not unique enough, even though I get the metering reference here. I do like that you're going in a different direction from the typical aperture symbols and camera lenses. I'd say do some more sketches and try to figure out a way to make a metering symbol a little more unique and interesting.

You can try to rotate the square to make them diamond. Also kern the photography to make it flush left and right side.

I totally understood the symbol right off bat, being that I am a photography enthusiast myself. I think it is a fresh idea to the photography logo game. Rather then a aperture or a lens. I just don't think the serif font goes well with the symbol that seems to be more representative of a San serif type style.. I don't know that could just be me. I think it won't hurt to go ahead and give it a try in a different type. Also give it some breathing room, the symbol almost looks like a after thought and was just wedged in-between Firm and Eyes. Would love to see what else you could come up with.
