Eos 350d Viewfinder and Eyeglasses

Hello.

I'm having trouble to see info numbers in my 350d's viewfinder. I'm wearing eyeglasses with approx. -4.0 dioptry on both eyes. I'have my diopter wheel set all the way to the left to -3 and i still can't see numbers clear enough with my eye glasses on. I've heard from lot of 350d owners that they had to put diopter wheel all the way to the -3 so that they can see numbers clear enough, even the ones without any dioptry. Are there any known problems with diopter adjustment on 350d's?

I have the 350D and now a 40D and like you I wear glasses, but I find that I am just able to read the info in the viewfinder with the adjustment wheel turned to max (but mine is in the other direction) Both cameras are the same with regard to dioptre adjustment, so they seem to 'agree' with each other. Lenses are available for the viewfinder if the range of adjustment is insufficient.
