SIGMA looks like they're about to announce an 800mm f/6.3 DG DN OS lens. It's highly unlikely we're going to see an RF variant, but we do like suprises.

Canon has two 800mm options in their lineup, the RF 800mm f/5.6L IS USM and the RF 200-800 f/6.3 IS USM. Both are great options, but something in the middle price wise would probably be a welcomed addition to the RF lineup.
Do you think it’s likely Sigma will make an EF version?I'd take an EF variant and slap a filter adapter on it... if the IQ better than the RF 800 f/5.6, and it was a good deal.
IIRC, the EF 800/5.6L is optically better. Not that the RF isn’t also excellent, just a little less excellent. Similar to the EF 600/4 II being slightly better than the EF MkIII/RF. In both cases the RF lenses are much lighter, a worthy tradeoff for some. But I’d say there’s room to improve with a dedicated design vs. a tailored TC in back.Because the RF 800 f/5.6 essentially incorporates both an adapter and an internal TC, perhaps there's room to improve on it.
True. Maybe this time?Then again, Sigma never quite reached Canon IQ past a couple hundred mm.
Not perfect. Sony limits such third party lenses to 15 fps and to be incompatible with TCs. The Sony folks complain.I guess this Lens will be perfect for Sony Users.

Sony doesn’t have anything modern at 800mm (until the leaked 400-800G is released).But if it won't be available in Canon mount, and Nikon already has an affordable 800/6.3 (excellent condition copies under $4500), I'm kind of confused why Sigma would even bother? I might be interested in a Canon RF mount, seeing as how my EF 800/5.6 weighs as much as a minivan, but that doesn't seem too likely.
I won't be available on Z mount either, Sigma's FF mirrorless lenses to date have only been for E and L mount. At the moment there is no 800mm prime available for E mount so this would be more than welcome. I suspect/hope Sony will make an 800mm f5.6 or f6.3 GM at some point.But if it won't be available in Canon mount, and Nikon already has an affordable 800/6.3 (excellent condition copies under $4500), I'm kind of confused why Sigma would even bother?

I had a great copy of the Sigma 150-600, extremely sharp. However, its AF on the R5 was slow and I reluctantly let it go.Have been using the Sigma 150-600 for years and never better than on RF. recently though invested in an EF Sigma 800mm f/5.6 great condition for £1400. Motor a little noisy but great optically and a great value proposition.
The issue is the Sigma lenses are great but you have to have the right shot. Unlike other manufacturers they haven’t focused on going lighter and they are big bits of glass. Problem being bit glass take a lot of movingI had a great copy of the Sigma 150-600, extremely sharp. However, its AF on the R5 was slow and I reluctantly let it go.
Vengeance because Nikon is using many Tamron lenses as OEM Z lenses?I won't be available on Z mount either, Sigma's FF mirrorless lenses to date have only been for E and L mount.
