I can't believe how many photos I've missed with my R9.

Funny, I have 20/20 vision according to my optician, yet, when I attached a +2 diopter to the back of my SLR, I was amazed how much better it seemed to my (getting older) eyes.

Nothing wrong with diopters for SLR's. I am now looking for more +2's for mine.
