Looking to acquire a interchangeable lens camera. I have pretty much narrowed it down to the Olympus E-M1, the Fuji X-E2 and the Sony A7. The only one I can buy locally is the Fuji. One question I have is the size of the EVF. Looking through the X-E2, I thought the size of the image was small compared to my memory of my old OM-4. How does it compare to the EVFs in the E-M1 (or for that matter the E-M5) and the Sony A7. What is confusing is something I saw in the description of the Olympus VF-4 that said it said it had a magnification of 1.48x, but that was comparable to 0.74x on a 35mm film camera, so I am thinking the magnification ratio is not comparable among different sensor sizes. Also, in a DPR review of the X-E2, they said the viewfinder on the X-E2 was larger than a E-M5 but smaller than a E-M1. I guess I'll have to look at them myself the next time I am traveling, but it would be nice if there was a definite set of comparable specifications. Are their significant difference? What are everyone's experiences?
