Off subject here, but what kind of mouse is that and do you like it? And why?
It's the Cyborg R.A.T.5. I like it cause I feel like there aren't much spot for me to hold that'd cause my palm to get moist. It has weights that I can remove as well and I love how everyone thinks it's some kind of alien or robot rather than a mouse. lol
On mine I set the aperture to f8 and the focus just shy of infinity and everything in the image is sharp. If light is a problem, f5.6 still works. Once you get below f5.6, though, the sharpness tends to fade a bit. At least on mine.
I think so, too. I just leave it on f8 if I have a tripod...
