Nice shot! I did a lot of testing some years back of various extenders on the EF 100-400mm ii and RF 100-500mm ii. My experience was that the 1.4x gave a better improvement on the EF vs RF but that the 2x is better on the RF. At 1000mm, it outreseloves the RF 800mm f/11. Why don't we have hummingbirds in Europe, it's most unfair!?I have been shooting some hummingbirds over the last few weeks with the R7 and EF 100-400 L II with the 1.4 ex III and had good success. The upside of that lens, aside from its sharpness, is its close focus capability. The R7 works well with the 1.4 extender. Today, I tried the same lens with the 2x III extender and the R5, which results in almost identical magnification (i.e. pixels on the bird) and thus equal illumination per pixel in spite of the additional stop imposed by the 2x extender (and that lens is still very sharp with the 2x). My sense was that the R5 setup was not as quick to focus as the R7 and also did not seem to hold focus lock as well. This may just be an EF lens issue, but I think it suggests that the complaints some folks have about the R7 AF may be based on taking advantage of its reach to the point that they just don't have enough illumination per pixel for the AF to work well. That said, I thought the following shot with the R5 was kind of interesting. This is at 100% when expanded.

I really like the little ball of feathers on the first one. So cute! Very nice series, shire guy.
You could always come to visit. My hummingbirds are not as exotic as the ones @foda has been snapping, but I do have an abundance, particularly in the summer, and a pretty good group chooses to winter over here in Oregon so long as I keep the smorgasbord fully stockedNice shot!

Happy New Year Click!ISv, Dragon and dcm,
Beautiful shots, guys. Keep posting.
Happy New Year!
There's a recent paper presenting "A biogeographic comparison of two convergent bird families" at: https://journals.plos.org/plosone/article?id=10.1371/journal.pone.0335195 which characterizes and compares the global scale biogeography of two nectar-feeding bird families: the New World hummingbirds and the Old World sunbirds."Why don't we have hummingbirds in Europe, it's most unfair!?"
It's actually even more unfair than you probably think (?): the oldest fossils of hummingbirds are from Europe, much older than the fossils from Americas...

Yes - convergent evolution can explain the huge time-gap between the fossils in Europe and the New World. And actually, with the fossils absent so far for that gap it seems to be kind of reasonable hypotheses.There's a recent paper presenting "A biogeographic comparison of two convergent bird families" at: https://journals.plos.org/plosone/article?id=10.1371/journal.pone.0335195 which characterizes and compares the global scale biogeography of two nectar-feeding bird families: the New World hummingbirds and the Old World sunbirds.
The paper has hummingbirds going back as far as 42 million years ago. Even 30 million years ago, the old ball looked much different than it does today and the little guys wouldn't have had that much ocean to cross to get from one continent to another as Pangea was still in the breakup stage. https://en.wikipedia.org/wiki/Panga...raphic_Map_of_Earth,_30_Ma_(Rupelian_Age).png And needless to say, the picture is only a scientific wild-assed guess of what the planet really looked like. Given how tiny and fragile hummers are, It is kind of surprising that any fossils have been found and not at all surprising that the fossil record is very incomplete.There's a recent paper presenting "A biogeographic comparison of two convergent bird families" at: https://journals.plos.org/plosone/article?id=10.1371/journal.pone.0335195 which characterizes and compares the global scale biogeography of two nectar-feeding bird families: the New World hummingbirds and the Old World sunbirds.
