Hello! New to posting after years of admiring everyone else's photos. Here's a male variegated fairy wren in non-breeding plumage.

5D3, 100-400L

Very nice picture. Welcome to CR  :)

While out in the canoe looking for turtles, I found a cormorant who did not want to share the creek with me.....

1. White-crowned sparrow
2. Ovenbird: This individual was displaying some odd behaviour. He wanted to get up on a birdbath from the ground. Instead of flying up like all the other birds, he tried to hop up even though it was way too high for him. It was rather comical, actually. He finally gave up and decided not to have a drink.

You know how I bang on about good the Sigma 150-600mm C can be at 600mm in the face of those who claim it falls apart after 400mm. Here's a little quiz. I took a shot this morning with the 400mm DO II + 1.4x TC at 560mm on the 5DSR of a male kingfisher, and I could compare it with a shot of the same bird from the same spot with the Sigma 600. Both were processed from RAW with no PP other than DxO PRIME followed by USM at 100% 0.9 px. First, the full scene of one at 560/600mm (reduced in size) to show the size of the cropping. Then the two shots.

1. Are they acceptably sharp, given the severe cropping?
2. Which one is from the Sigma?

Two very nice shots, Alan.

Both are acceptable...But I prefer the second one. To my eyes, it has more details and better sharpness.

assuming all settings are the same in both photos, and focussing is spot on for both, I would say the first one is the Canon 400 DO - is just 'crisper' like it has more contrast, but I agree the difference is slight.
I was looking to compare the shades and detail in the blue but unfortunately it is only really visible in the second image.

The difference is so slight I wouldn't hazard a guess. I use the Sigma 150-600 C all the time at 600mm and like it a lot. I find it quite acceptably sharp and the AF is good. 🤓

It's pretty clear that this is the Sigma: http://www.canonrumors.com/forum/index.php?action=dlattach;topic=1280.0;attach=166893;image

There is a noticeable drop in sharpness and contrast.

Alan, your tests really are great, and it's incredibly interesting to see.

It's funny how the line pair tests show such a drastic increase in resolution on the Sigma 150-600C over the 400DO+TC, when these images show the Sigma at a disadvantage.
(Unless I'm totally wrong in which case these results would be quite shocking.)

It reminds me of my own comparison between the Samyang 800mm Mirror lens on Full Frame and the Canon 400f5.6 on a crop body.
Detail between the two lenses is almost identical, but the Canon lens has much better colour transmission (and obiously the mirror lens is manual focus only).

Alan, if you don't mind humoring a skeptic next time you're in the mood for comparing lenses, what I'd really like to see is a full frame image from the Sigma 150-600C downsampled to the same size as a 1.6x center crop from the bare 400DO without any TC (which should effectively emulate the 7D2).
In the TDP tests the 7D2 on a 400mm lens gives longer effective reach while only giving up a slight edge in terms of center sharpness when compared to the 1DS on the Sigma 150-600C.
The 5DS has the same pixel density as the 7D2 so cropping a 5DS image to the same resolution as a 7D2 image should be a fairly precise simulation of the crop body (if only we could get a 7D with no Aliasing filter).

Given the good results shown this far I don't expect the center crop of the 400DO to match the Full Frame results of the Sigma, but if it's close enough then once you factor in the increased AF speed and smaller overall package, cropping still seems like a better option than buying a longer third party lens.
On top of that, if you're on Full Frame then tracking BIF at 400mm will also be much easier than using 600mm glass.

I totally agree with you.

Even in the wood, we can see more details. The third picture is softer.

The 400mm DO II + 1.4xTC on the 5DSR gives the best IQ of all of my lens-cameras combo (when 400mm isn't enough). The speed of AF (and that of the bare 100-400mm II) eclipses that of the Sigma. The lens plus TC costs 10x more than the Sigma, however, and weighs 600g more and is more difficult to pack for airline travel. So, I prefer to take the Sigma for travelling and hiking because the pros, including zoom, outweigh the cons for just a little loss of IQ.

The test conditions were not exactly fair as the Sigma photo done last month was hand held at 1/400s whereas the Canon yesterday was hand held at 1/1600s. Speed does make a difference for these extreme crops. I'll post another comparison I did last year with different lenses.
