jeff89 replied to the thread Canon Says it’s up to Sigma to Make Full-Frame RF Lenses.
The way it was presented was that Sony cut the AF speed and max frame rate for the Sigma lens (diabolical), keeping peak performance...

Ran across this one in my archive. I've seen many GBHs, but not very many GBH tongues.

Great shots, ISv. I especially like the first one.

Sigma should also produce a few tiers of microphones, on-camera flashes, and dual chargers for Canon users alongside their lenses. Canon...

When you say "Sony limits the AF speed", is that a diabolical move on Sony's part or is the Sony system simply incapable of providing...

I don't know if @foda has success with the Orange-cheeked Waxbill but today I didn't (~40 min. searching). Took just few photos of House...

This is what shows up on my R1 with lens that forces distortion correction attached (not as obvious in the iPhone pic, but the...

Nice photos/story with happy ending :). I don't like the gulls when they behave like kleptoparasites! On other hand I have a lot of fun...

I like many would buy the Sigma 300-600 f4 and personally, the Sigma 135 f1.4 Art (I have the EF 135, RF 135 and Sigma EF 135 Art) and...

My Sigma 17-40 also shows "not available" for distortion correction, however if you compare the RAW with an OOC JPEG you'll see massive...
DocInfoSci replied to the thread Canon Says it’s up to Sigma to Make Full-Frame RF Lenses.
Out of curiosity, is it known whether “Canon allows…” means official support such that the lenses will be forward compatible like...

AJ replied to the thread Canon Says it’s up to Sigma to Make Full-Frame RF Lenses.
I'm still scratching my head.
1) Sigma already has spent the R&D money to develop full-frame lenses like 300-600/4
2) Sigma already has...

I would gladly buy the Sigma 300-600mm if they released it in either EF or RF mounts.
Dragon replied to the thread Canon Says it’s up to Sigma to Make Full-Frame RF Lenses.
True, but the relevant conversation with the Canon exec was reported well before April 1, so the article is legit.
Dragon replied to the thread Canon Says it’s up to Sigma to Make Full-Frame RF Lenses.
I think that answers my question. Unless the lens is relatively distortion free, that missing bit, while not much of an issue for a RAW...

My Sigma RF-S 10-18 f2.8 and 18-50 f2.8, when mounted on my R7, show "Not available with the attached lens" for distortion correction...

Sorry, I have the completely opposite opinion.
Why should Sigma (or any other 3rd party lens manufacturer) be 'required' to make enough...

I did some searching for lens sales numbers. An estimate for Sigma is ~1 million/year, across all mounts, including legacy DSLR. For...

neuroanatomist replied to the thread Canon RF 300-600mm Update…. Again.
Yes, that was subsequently corrected with AFMA.
Dragon replied to the thread Canon Says it’s up to Sigma to Make Full-Frame RF Lenses.
So a question. The RF mount clearly provides for extensive geometric correction (and I believe even includes correction for focus...
neuroanatomist replied to the thread Canon Says it’s up to Sigma to Make Full-Frame RF Lenses.
