I have only used a G1 with MF, but was curious what others felt about MF usability and the different M 4/3 bodies.
There are various factors that influence ease of MF-
-LCD resolution and visibility
-EVF capability and resolution
-Ease of screen magnification (i.e. how many button presses)
I'm hoping for some subjective impressions rather than just arguing bullet points, because actual usage often turns out to be different than anticipated.
For example, even in-body IS could have an effect I think. If you use the LCD on an EP-1 at arm's length to MF, perhaps the built-in IS helps in terms of keeping the camera stable. Or maybe you are happy with using the LCD on a GF-1, because it has higher resolution, etc. Or maybe resolution doesn't matter that much, since you need to magnify anyway to get sharp focus...these are the sorts of things that you figure out after extensive real-life usage.
So I'm not hoping for some sort of final conclusion about which is best, I'm wondering about what people like better and why. I think the G1 is pretty versatile for MF, my only wish is that you could set a single button to magnify the screen (for me magnification is necessary for consistently good focus, YMMV.)
