I've got a FED-4 and haven't used it all that much, i'm now on my 4th roll of film with it but i can use it without looking at it now. The meter doesn't work so i use the sunny 16 rule and basically only use F16, F11, F8 and F5.6 and shutter speeds of 1/500th, 1/250th and 1/125th... it's very easy to tell what's what by feel, as those three shutter speeds are grouped closely together and turning the aperture ring all the way to F16 and work a click of two back works for me. I wear glasses, too, so i don't even bother trying to look view the VF/RF, i can't see enough of it to make 'fast' use from it.
