- PetaPixel 8.5/10
Sharp, compact, and with a focal range that is sorely missing across multiple lens mounts, this Sigma lens checks nearly every box.
-
This large-aperture telephoto provides fine image quality in a remarkably small size, and at a relatively accessible price point, too.
-
This is a great value, flexible photographic tool, and it comes highly recommended from me!
-
Performance is not in question, the results are almost universally excellent, the price is keen, so we have a highly attractive Editor's Choice.
-
Ultimately, this Sigma makes a compelling case for using a crop-sensor camera instead of a full-frame body. It’s a proper pocket rocket!
-
I really like this thing. And more importantly, I think this is exactly the kind of lens APS-C needs.
