Need the chin rest to steady the patient's head, and to make it comfortable for them. C'mon, you should know this - when was the last time you had an eye exam. Oh, and if you were just being sarcastically funny, then, "Ohh...tee hee hee hee" =P
Yeah, think sarcastically funny. I'm a photographer and roll my eyes when people get all worked up in a tizzy over how many megapixels the newest camera has...as if they're even going to print an 8x10, much less a poster.
Retinal photography is pretty much restricted to those who are having serious problems that require monitoring of the stability of the retina.
As an aside it's pretty interesting to have photo's like this taken because they take multiple pictures in rapid succession. Although that might not sound interesting, the bit that is interesting is that the rapid flashes deplete your eyes of the chemical compounds needed to see color. After the flashes you are momentarily (less than a second) blind, with black and white vision coming then color coming back slowly as your body recreates the chemicals used to see color (the first color you see is red so the first thing you see is a red/pink tinted world, it's quite trippy).
Don't try this at home BTW, the flashes used in retinal photography are different than those used in conventional flash photography, enough so that doing the same thing with a conventional flash could possibly damage your retina.

Motorized filter changing and chin rest? Three imaging modes? Who cares -- how many megapixels does it have?!?

Um, having more megapixels and thereby a larger possible photo means the the picture will look sharper and clearer in smaller sizes too. Duh.
Does buying a machine like this mean my ophthalmologist will have another excuse to overcharge me? It already costs $180 for just an exam and fitting.
