I use 28, 50 and 75mm Leica lenses with the GXR-M. I focus fine with the 50 and 75 (I use 4x magnification and no focus peaking on the read LCD). But with the 28, I have difficulty nailing focus and increasing to 8x or using the EVF don't help that much. There always seems to be a range where the subject is roughly in focus but it's hard to tell whether I'm hitting the perfect spot. Once I blow up the image I see that I can be off by some amount, say 1 foot. How do focus your wide angle with the GXR-M? Do you use the LCD or do you simply zone focus? Thanks.
