R4A... 0.52x finder (hardly less than 0.58) and single 28mm framelines with plenty of breathing room. Depends on how important that VF is to you, how particular you are about the body, cost savings, etc. but I thought I'd throw that out to muddy things up a bit 😀
Otherwise, the ZI is the best compromise for built-in VF range: decent 85 and 28, gorgeous 50 and 35. Like Double Negative, I shoot with a 25mm Biogon on mine all the time. How many people do that on a 0.72x M... and remember the ZI is higher magnification at 0.74x. Cosina must be doing something right with their VFs.
