Brainiac; are those your shots? Do you have the APO 180/2?

Yes, they are my shots. I used to have the 180 f2, but I sold it to a friend once I found a lens I liked better (gasp!). APO-ness isn't the only quality I look for in a lens, and I'm prepared to overlook LoCA and even a bit of CA if I think other factors make it worth the sacrifice. My friend still uses the 180 f2 with his 5D's, and I can borrow it whenever I like. It's a great lens. I love the compactness and the close minimum focus distance (1.4m), which makes it a superb portrait lens. I always say I'm brand agnostic but nobody ever believes me ;-)

I know it's blasphemy on this thread, but it was the Canon 200 f1.8. It's brighter, with lightning fast AF, and I very very slightly prefer the way it draws the picture, notwithstanding that it has slight CA and more LoCA. I would have liked to keep them both, but I'm not a millionaire.
All this is OT so let's get back to the beautiful APO shots that everyone is posting.

Canon makes no true (super)apochromats, correct?
As far as I understand, most if not all L lenses are *somewhat* apochromatic, they control LoCA to a degree, but none gets rid of it altogether.

Great shot. I love the softness of it in terms of mood.

Canon's top telephotos qualify as apochromatic once they're stopped down a little. None of the fast lenses here are apochromatic wide open, though many control CA well enough that it's not visible on current sensors. "Somewhat apochromatic" is as good aterm for that degree of control as any. Defocus colour can still afflict a lens with no apparent longitudinal CA. Yaddah yaddah.

Here's an old sample/test I did right after converting my FD 85/1.2 SSC Aspherical. I dug it up for another thread and thought it might as well go here.
Wide open on 5D:

100%:
http://www.cogitech.ca/photos/SSC_Asph/img_2209_1.jpg
This sample was taken while I was still tweaking the rear element position. In it's current configuration it is slightly sharper and has even less LoCA.
Not APO, of course, but do f1.2 lenses get any better?

Suh ... weeeeet !!!
I'M SO SOLD ... on the close range. Do you have any midrange & infinity shots that are equally killer.
BTW ... was this straight RAW, RAW/PP or jpg from camera, etc.?
Thanks.

WOW! I noticed this "APO" thread now only. Great images here. Let me contribute with my Voigtlander 125/2,5 on my Nikon D300... 
This is one incredible lens, even compared to my Leica APO-Summicron-R 90/2 Asph that I've converted to Nikon-F mount using Leitax products. The CV125/2,5 is not only perfectly APO corrected and characterized by outstanding resolution figures: it renders also and absolutely beautiful bokeh and reminds me of my beloved Summicron 180/2...

PSquared (what is P),
those first two shots have a nice 3D-ness to them (*gasps* come from the Zeiss faction
), especially the fish and the noodles next to it.
I know Leica isn't normally known for that, but a few of their lenses sometimes to exhibit it. The 180/2 portraits from Richard also show a bit.
A lot of nice shots here!

Glad to see this thread bumped back up. In an effort to keep 'er going, here are a couple from the CV 125/2.5:

Would Sigma APO designated glass be considered true APO ... or should it be considered as a near APO for a compromise in $$$

I note several very sharp shots with Sigma 150 f2.8 Macro. I note it is available in only Nikon and Canon mount, whereas the 180mm f3.5 Sigma macro is available in Sony 900 mount. Anyone have experience with the 180mm version? As sharp as the 150mm version? I already have a Sony G 70-300, but it's sharpnes I don't think is equal to what I have seen here.
Thanks

I don't know... Here is a quote from page 4 of this thread:

Sigma's definition is not much weaker than the others', as none of these lenses are "really" APO wide open. Some even have easily noticeable levels of CA and other aberrations. But most of the lenses shown do become technically APO once stopped down somewhat, and that's no mean feat.
As a general rule, put more stock in MTF charts, or spot and ray fan plots if you can get them, than anything that might be subject to a marketing definition.
But you don't agree it seems... Would you like to explain?

My only disappointment with the Leica APO Elmarit-R 100/2.8 was the defocus CA that sometimes can creep in. Granted, it doesn't show often, but...
Test sample:
On the other hand it was an improvement compared to the OM90/2 Macro. I guess a CV125/2.5 is the way to go. Or Sigma?
