I've got a couple of FT bodies but don't use them much because I find them hard to focus (I wish they had a split image focusing device). I've heard that the plain F, without the built-in meter which siphons off light, is easier to focus.
I'd appreciate reading the opinions of those have used both and can speak to the issue. Thanks.
I have both. The F is easy for me because it's bright and I don't wear glasses. I like the microprism screen in the FT for accurate focusing. My FT's half-mirror is deteriorating though, making the view somewhat "fuzzy" and the microprism bit almost essential.
I've never had any out-of-focus shots with either camera.
I have always felt the "bright" viewfinder of the F is overrated. The increased depth of field of the half frame format is very forgiving and I've never had problems with focusing the FT. You can pretty much use hyperfocal settings and be good. Having the on-board meter (and single stroke film advance) is a much greater advantage than any increase in viewfinder brightness.
If you only shoot negative film and don't have a pressing need for the meter, try an FV.
Maybe these pictures will help. On the left is the viewfinder focused, on the right, out of focus (pardon the dirt - cleaning the VF would require disassembling the camera.)
