I'm interested in moving from an AE-1P to a "new" F-1 as I prefer mechanical cameras. I was wondering if anybody can weigh in on the eye-level finder of the New F-1 vs the AE-1? The info I find lists the AE-1P's finder as having 0.86% magnification vs the F-1 at 0.8x. Is there any difference or is this just different terminology. Also, any difference in brightness?
