Sigma 50-100mm f/1.8 HSM DC ART ... - Klaus - 06-10-2017
Vignetting:
50mm f/1.8 FF: 11.4 stops
100mm f/1.8 FF: 4.88 stops
50mm f/1.8 APS-H: 1.7 stops
100mm f/1.8 APS-H:1.7 stops
Just from a vignetting perspective APS-H is feasible.

So only 0,3 stop more vignetting at 100mm than the 16-35 III has at 16mm.
Does it get better or worse stopped down? I'm not asking for precise figures, just an estimate.

I doubt that APS-H vignetting is an issue one stop down.

What goes downhill towards the edges of the frame as well ?

Here is a review from a user shooting APS-H

Seems like this is a fine lens for APS-H shooters. Too bad Canon discontinued this format.

The review will be up tonight. It's hopeless but at least I have to try proof-reading ... ;-)

As for the format itself... I guess there's enough copies of the 1D Mark IV floating around in the used markets - so go grab one! They probably last forever unless the owner chooses to abuse them (and even then...) I know I'll be using mine until it falls to pieces, or until I kick the bucket myself. With the ridiculous toughness of the 1D series, I'm not entirely sure which is going to happen first... maybe my nephew Yuki is going to inherit my battered unit some day.
