F5: Sigma 18-35 useable with Metabones Speedbooster?

[Ben Scott]

Hi all,

Just wondered if this lens/adapter combo is usable at any range? I assume it vignettes pretty heavily at the widest settings but how is it through the other range?

Cheers,

Ben

No.

It's an APS-C lens.

It will physically work but show vignetting on most focal length...

Sure it's an APSC lens like the Tokina 11-16 but that is absolutely fine at 16mm on full frame so wondered if anyone had actually tested the Sigma and had any real world experience of it.
