So far I have found 3 glaring issues with Sigma's lenses.
The thing is the specifications on paper doesn't really reveal these issues, so Sigma is hiding pretty well behind the spec wall.
But once you look closer:
- Sigma's manial mode focus ring is completely fucked up. Their lenses can't do smooth stepless manual racking.
- Sigma's aperture ring isn't as stepless either. They are going cheap here as well, their smallest adjustment step is 1/3rd, whereas Canon RF lenes can do 1/8th step, much finer adjustment.
- Sigma's close focusing magnification ratio is often unusable across the whole frame, and only the center is sharp.
I'm probably overreacting, but it's really annoying that you can't figure out these things from looking at the specs, and you potentially find out too late after you made the purchase.
