Trying to understand cameras is wild. Okay. So the Sigma 18-35 f1.8 Art is a super-famous great lense. It is for a smaller sensor-size called APS-C rather than "full frame" which I use. Full frame is of course not the largest sensor size.
Is there a larger variant of the lense? Of course not. Well kinda. The 24-35mm f2. Which is supposedly still noticeably different.
The 18-35 can be used on a full frame but from 24 to 35 apparently. But maybe is better, kinda, anyway?
Exhausting.
