The 50mm Leica M primes (with lens adapter) are highly appealing for use on the 36-megapixel Sony A7R for multiple reasons: compact size, ergonomics, ultra high performance, that wonderful high-res Sony EVF for focusing precision and best of all, recording that performance to a 36-megapixel sensor is more rewarding than the 24 megapixels of the Leica M Typ 240.
Prompted in part by a few recent reader inquiries and my own interest in the foregoing, I set out to answer a straightforward question: I wanted to know whether in the field it would be possible to mount a world-class 50mm lens and obtain peak-quality images with the A7R. Or whether I would need to be concerned with the A7R shutter vibration. And/or whether the limitations would be acceptable to migitate, somehow.
That Sony A7R sensor is a first rate performer, and at 36 megapixels, any Leica M owner should ask the above, because why not get state of the art image quality at 36 megapixels instead of 24, and with far superior focusing capability (EVF)? In other words, could the Sony A7R be considered a superior platform over the Leica M240 on the basis of a better EVF and notably higher resolution (and at 1/3 the price)?
(This is not a lens test, it is a camera test). Included are thoughts on deciding how to approach the A7R, given the results.
