p.1 #1 · Any 400 2.8 IS with 2xIII samples?


I've been through the stuff on POTN and done a google search, but not giving me what I'm looking for. I am interested in seeing some samples (body doesn't matter much although 1.6x would be nice) from the 400 2.8 IS and the 2xIII TC specifically of wildlife or birds - NO SPORTS. I know AF will slow down, so that's not an issue. Any comments from users would be welcome too, especially if you have compared the version II and III with this lens.

I don't have a 2x TC III, but I often use a 400 2.8 IS + 2x TC II on birds, most of the time wide open. AF is slowish, but IQ even wide open is very decent.

From all the comparative tests I've seen, the 2x III is at least optically as good as or a tad better than the 2x II. Thus, I believe that the following examples might have been a bit better or at least as good if I used a 2x III instead of a II.



Lowland White-eye (Zosterops meyeni, a near Philippine endemic, 4 inches total length)


Canon 1D MIV + 400 2.8 IS + Canon 2x TC II, 800 mm, f/5.6, ISO 1600, 1/320 sec, 475B/516 support, manual exposure in available light, near full frame.









Canon 7D + 400 2.8 IS + Canon 2x TC II, 800 mm, f/5.6, ISO 1600, 1/320 sec, 475B/516 support, manual exposure in available light, uncropped full frame.









Canon 5D2 + 400 2.8 L IS + Canon 2x TC II, 800 mm, f/9, 1/250 sec, ISO 200, bean bag, uncropped full frame resized to 1200x800.

Pogi Romy is one of few "birders" who actually know how good 400 f/2.8 IS MkI is, even with the TCs Naturally, sports photographers have known that all along.
I believe if there is one big lens Canon can not afford to compromise on, that would be 400 f/2.8 IS.

This is about 66% crop of a handheld shot made with 400 f/2.8 IS MkI + 2xTC MkIII on 1DsMkII.

For those "newbies" who stumble upon this thread, be aware that both Romy/Liquidstone and Petkal bring some serious skills to the table.

I.e. they can truly make gear shine! ;-)

My guess is this lens was historically unpopular with birders because it was so heavy. The IS II has seriously addressed that, as you have frequently mentioned and demonstrated. It would seem for small bird photography, given it's close minimum focusing distance, it can be quite effective.

Yes, the 400 2.8 IS is very heavy (it's actually heavier than the 600 f4 IS!) but you're right, its 3 m MFD plus its good IQ with a 2x TC makes it a very effective tool in small bird shooting up close.
