A quick exchange with Mary Anne prompted me to post up the question, because I have no idea whether or not wearing reading glasses while looking through the viewfinder is a common thing. I wear glasses for reading but not longer vision, which is very good.
I tried it a few weeks ago, because I was wondering whether the eye is focussing on the mirror plane or on the reflected object as if it was the real distance away. I was blown away when the view in my view finder seemed much sharper when I used my reading glasses.
For those who use reading glasses, is it common to use reading glasses through the viewfinder?
Forget I ever asked that. Read another post about a similar thing (search is wonderful) and from that, went to my camera manual and found a Diopter adjustment thingy. I cannot believe I have had this camera for over 12 months and I just found that. Always learning.
