I‘m also tempted by the Sigma 28-70 f2.8. However, I already have a 24-70mm and I like 24mm because it provides you with a lot more versatility.
Any (valid) reasons to pick the Tamron and not the Sigma 28-70mm 2.8?
Edit and btw.: Do you mind the different directions of rotation of the Sigma zooms? I can already tell when I rarely use the Sigma 24-70 that I‘m always a bit “confused“ at first ...
So I wonder if the combination 17-28 (Tamron) + 28-70 Sigma is a good combination in this regard. Is it just me who has these concerns?
