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

Yes, that was subsequently corrected with AFMA.

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.
I don’t think so. When the RF mount first came out, there were no third-party lenses for it. That is a recent development, and only for...

nice frog in the green, but it looks like sharpness isn't exactly on the frog's eye, so the camera's AF struggled a bit ;)

According to CIPA, the RF version has a tad better IS, but in real life it shouldn't make any noticeable difference. I have the EF 600mm...

If I remember correctly, when Canon first came out with the RF mount, these was something strange with the image on third party lens...

I do not own a 600mm lens but recently traveled to South Africa in July 2025 and used the RF 100-300mm 2.8 (CPS trial run) lens. I...

It is fast, no question, but as I said the difference isn't noticeably big when we shot w/o TC side by side. But with TC, the difference...

that's true, I agree
I know, Canon revolutionized the common tele lens design with the EF 600/4 III by moving main parts of the front...

Canon's ways of limiting Sigma are many and complex, not least because the intellectual property levers they have operate differently in...

I disagree with your conclusion. Sigma already makes FF lenses that could be ported to RF. They have a mount conversion service costing...

A red kite or a red shi*e?
DocInfoSci replied to the thread Canon Says it’s up to Sigma to Make Full-Frame RF Lenses.
Makes sense. I agree, it’s not the contract (license) that’s the issue here but some other business constraint. I was thinking more in...

All of Sigma’s current RF APS-C lenses DO have control rings: for the older ones it doubles up as the manual focus ring (same as all of...

Well, it would put the ‘fluorine’ (fluorocarbon) coating to the test. :poop::sneaky::sick:

I'd say I'm definitely hoping for something more like $8k, and I'm fully prepared to be disappointed lol. The 100-300 f/2.8 L definitely...

I hope it missed you (and your camera and lens) :ROFLMAO:.
neuroanatomist replied to the thread F00 conundrum.
Nope, I believe I stated that it didn’t solve my problem (or at least, that’s what I meant to state). That was before I deleted all of...
P-visie replied to the thread F00 conundrum.
You stated (or I interpreted it that way) in another thread that the problem was solved by cleaning the contacts. Is that correct?
