My only experience in that range was with Canon...their 35-70 f/2.8 - f/3.5. (it also has Macro)
I used it a few, scant times, and never used the Macro.
It seemed to produce a "Good Negative" with FP4
Until your post, i forgot i have it.
I am afraid i simply do not use Zooms, so that is all the "help" i can be.
Canon made 3 or 4 iterations of this lens. I believe mine is the first model. It is rather big, with an integral lens hood and the Silver, breech mount.
(thanks to you) I will be selling it if you become interested after what you learn from your post here.
Good Luck with whatever you choose.
Woops.... i see you are in Spain. no need to consider buying my lens.

Canon made a lot of these 35-70. i would think you could find one in your area.
