I bought a Sony 40mm f2.5. I posted my thoughts about it and I posted pictures and you replied
What? No 28mm setting? :D I've no doubt it's a nice lens but being physically shortest at 50mm and extending to 24mm seems rather odd to me. As I included the 28-70mm kit lens above I'll add that that lenses in / out action through the zoom range also seems odd. I always feel a bit...

I haven't been able to get out much with it yet. I was going to go out today with it but due to the weather I didn't bother. I have to go out tomorrow so I'll take my A7 and that lens but if I use it or not depends on the weather and how I feel but I have actually used it in pouring rain once already
I think it is a good lens but it might be a little tight for me. It might be stuck between my liking for 35 and me reaching for a 50mm if I want tighter. Once I've given it a more thorough road test I'll decide if I'm going to keep it or try and sell it here.
PS.
One thing that struck me today is that because the performance seems so good across the frame and into the corners this might be a good lens to do panoramas with.
