Thanks so much, yip, this lens is a real beauty. Apart from the quality of the optics, the other game changer is that I can now easily fit my 500 f4, 16-35, the rf 70-200, R5 & R6 in one bag. Only downside is that it won't take a teleconverter but I don't really use them that often.

Hopefully, the third-party TC makers will come out with TCs that work with all RF lenses. If they can't reverse-engineer the lens/TC communication so that proper reporting occurs, they could make non-reporting versions, which are simply tubes with glass in them and can be invisible, electrically.

Personally, I'd be interested in 3rd-party TCs capable of reporting that had switches in them to turn off or alter the reporting, so I could have proper reporting when AF needs are modest, or faster AF without reporting, when that is more important. I regret that every single TC that I own is reporting, and apparently taps into the pass-through wires and is electrically significant and causes all kinds of potential incompatibilities with the R5 and lenses, especially IS lenses, where the IS often bangs periodically. I don't know if this is an EF-lens-only thing, or a universal issue that includes RF lenses, potentially.

Wouldn't that cause problems with the IBIS? The focal length would be reported to the camera incorrectly.
In fact, you commented about this in another post:

Does it report the correct focal length to the body for the purposes of IBIS? Most of my 3rd-party lenses that are a decade or more old report the wrong focal length(s), making IBIS worse than no IS on those lenses.

The swimming viewfinder in the previous post is the result of the IBIS doing the pitch and yaw corrections thinking that the focal length is much longer than it is (85mm, for example, with the Sigma 12-24). A non-reporting TC with a non-IS lens makes the IBIS think the focal length is shorter than it is, which allow partial correction of pitch and yaw. With lenses that have their own IS, IBIS does not correct pitch and yaw, which are the only two axes that are focal-length-dependent.

All true, but a partial correction, while better than nothing, doesn't give the full advantage of IBIS. You won't get the full 8 stops that the combination is capable of giving.

Thank you and was sunset time but facing East so that’s probably why haha. Maybe should change the title.

No, the title is fine, as the picture was taken during sunset :-)

Looks like a snake. Am I wrong?

Regardless, it is quite a nice photo.

Great capture but if that was in my garden I’d never step outside again or move house haha
