Sigma 56mm vs Viltrox 75mm
I know this is pretty common comparison and it feels like people are generally leaning more towards the Sigma 56, but I already own Sigma 17-40. I want a lens specifically for portraits and maybe street/people, I have a feeling that due to already owning Sigma 17-40, the Sigma 56 might not give me much difference where Viltrox 75 would? I still plan to use 17-40 as my main/daily lens, so Sigmas portability does not play too much here for me.
Thank you in advance!
