I'm just about to push the button on an A7 and Novoflex mount adapter in the hopes it will give me a good digital body to work with my Leica R lenses. (I've got a line on a new A7 body only from a broken up kit package for $1400 ... seems like a good deal to pounce on.)
I've got these lenses:
'65 Summicron 50/2
'70 Summilux 50/1.4
'79 Summicron 90/2
'81 Elmarit 135/2.8
'79 Elmarit 180/2.8
I'd also like to find a similar age wide ... 21, 24, 28 mm ... so that I can use it on both the Leicaflex SL too.
Based on what I've read here and elsewhere so far, it seems to me that the A7's 24 Mpixel sensor is a bit more forgiving than the A7r sensor and should work well with these older lenses. If anyone's used these lenses on either A7 or A7r body, I'd love to hear your experience.
