Do any of the non-SLR digital cameras have a decent manual focus macro capability? I’m looking for a smaller digital camera with manual macro focus to be used in a health clinic to photograph the iris of people’s eyes. The iris will be illuminated from the side by a fiberoptic light source. I already have a Canon 10D SLR with a 100mm f2.8 macro that works great but I’m not willing to give it up for this purpose. A problem I’m having with the non-SLR digital cameras that I’ve tried is that the autofocus will lock onto the eyelashes instead of the iris. For this reason I need the macro function to have a decent manual focus feature. A price around $500.00 or less would be nice but if necessary up to $1,000.00 would be okay.
