Like how Nikon has been aggressively marketing the internal diameter of the Z mount being 17% larger than the Nikon F mount, the larger mount allows more flexibility in the optical design of the Z lenses just like their newest 58mm f0.95 Noct lens. Today I won’t be testing on the 58mm f0.95 as I’m not really a fan of manual focus. We will take a look into how Nikon latest 50mm F1.2 lens will hold up against the popular 3rd party lens – Sigma 50mm f/1.4 Art series.
Sigma adds Canon Lens Aberration Correction and Nikon bug fixes with new firmware updates
Sigma has released a range of firmware updates for some of their Art, Sports and Contemporary lenses for both Canon and Nikon to add feature support and fix a few bugs. There’s also an update for the Sigma MC-11 adapters expand lens compatibility.
Sigma warns of issues with some Art and other lenses on newer Canon bodies
There’s two things you can be fairly sure of whenever Nikon or Canon release a new DSLR. The first is that you’ll need to wait for Adobe to update ACR/Lightroom to be able to read the raw files. The other is that some Sigma lenses will have compatibility issues, and need a firmware update.
And so, Sigma have released an advisory for certain Art and other lenses when being used with some of the newer Canon bodies. Those bodies include the 6D Mark II, EOS 77D, Rebel T7i (EOS 800D) and Rebel SL2 (EOS 200D). Fortunately, the cause of the issue is fairly specific, so the temporary workaround is quite simple.
