A very brief summary...i've been shooting with a M9 for a couple of years now (mainly street, a couple of photos of family and friends thrown into the mix).
For a want of better high ISO performance in low light, i decided to try out the A7. (The M240 was tempting, but i simply couldn't justify the price - not when i'm saving for a new place)
Long story short, i plonked down the moolah for a used 50mm 1.5 Nokton ASPH and i'm very happy to report that the combination is very, very satisfactory (to me at least!) - even more so than the 50mm Nokton 1.1 that i've tried on the A7. (The OOF areas seem like a pre-asph lux imo, to me at least) The 50mm 1.1 is a little too busy for my liking, but still an excellent chunk of glass for the price.
Some sample shots (Mostly wide open)
