I am currently shopping for a digital camera and I remember reading some recommendations on this forum, but have no idea where. I am strongly considering the Canon S400 elph, but I have a couple of questions: The S400 does not have manual focus, will this present a problem for close-up/macro shots of the eye? Is it possible to take pictures through the slit lamp microscope, and if so how? Any other recommended cameras? I would like it small enough to carry conveniently. Thanks for the help!
