Does anyone have any recommendations for a lightweight and/or compact 135mm or longer prime lens for use on a A7R (or A7S for that matter).
Lightweight is fairly key as my back problems are now so acute that I really can't lift monster lenses.
Does such a thing even exist?
I can just about use the FE 90/2.8 but a bit longer for some purposes would be good.
Thanks for advice.
