Does anyone know when this lens is expected on the shop shelves?

Viggo, those of us still waiting appreciate your updates, and this latest, how you try different AF settings for better results, is another helpful one.
I think the strongest selling point of this lens for me is its sharpness across the frame, so being able to compose with at least any of the 5DIII's cross-points is an essential part of how I imagine using it. Hopefully this won't be just a dream as AF issues get addressed...
You can't really trust the two outer points on each side, the one next to center is okay, but only center is fully trusted. And that kind of defeats the purpose of corner sharpness... The 85 L keeps delivering at any AF point...
The most anal people I know about image colour are flower photographers and ceramicists, ever photograph a red flower and it not look anything like the flower did? Try deep blue, purple, and mauve flowers, they are a very difficult to get accurate and you have to use a camera profile specifically for the light you shot in.
A lot of trouble with flowers is even more that people seem to stick to sRGB which makes many flowers impossible to show correctly. A wide gamut monitor will give you a much better chance (of course it's true that the WB and profiles and all can still mess with things).
True, sRGB is too endemic. It's really time we started moving towards larger gamuts. Even AdobeRGB isn't quite good enough, as most of the gain with AdobeRGB is in the greens. The deep reds and blues and violets, where a lot of flower color resides, don't really change much with AdobeRGB. ProPhotoRGB may not be the best either, as its extent is even beyond that of human perception, but it's still got the ability to map almost every color at the richest saturation the human eye can discern.
Sadly, even 10-bit screens with 14- and 16-bit 3D LUTs are still not quite good enough at showing reds. I have these Peonies that are just about to burst into color. I've tried photographing them in years past, and I've never been able to get the reds and pinks to come out right...they clip and there is little tonality. Bleh. It's such a pain. My roses have a similar problem, however most of those have a deeper red that actually does fall into gamut for AdobeRGB.
No question, though...rich saturated color, particularly in the non-greens, can be a real problem.
Interesting. The way people rave... it sounds like the 24-70 is on par with primes... ugh.
you may want to wait a bit longer, since it is said to be updated very soon.Your post sounds like that of a lens snob - this is one of Canon's best lenses and other than the aperture being slower than the f/2.8 versions, I have yet to hear anyone complain about this lens. Besides, there are exactly zero rumors (on CR) about this lens being replaced so I don't know what you're talking about.
I have it and also Sony Nikon 70-200mm f4G lenses and I compared them side by side many times, in absolute term the Canon f4LIS is still a good lens but it shows its age compared to the Sony and the Nikon,espeically to the Sony.
and imho, the Canon f4LIS and Nikon f4VR are overpriced compared to the excellent Sony 70-200mm f4 SSM , the Sony comes with tripod mount and it is about 100US cheaper than the optically inferior Canon f4 70-200mm and the Optically as good but heavier Nikon..
I tested them all on my A7R and see the differences, the Sony was clearly sharper than the other 2 at 70 , 100, 135mm wide open , but at 200mm end , the Nikon was the better lens at f4 , but stopping down to f6.3 , the Sony becomes better than the other 2 again. I also compared the build quality of the 3 lenses, to me the Sony seems better made lens but a bit bigger than the Canon, the biggest one is the Nikon f4 and it is a bit longer than the Canon and the Sony. But honestly I prefer the look of the Nikon lens since it is black and less conspicuous in public. but if do not care about the color of the lens, but only optical quality and AF accuracy , then the Sony wins hands down here. and after comparing the 3 , I am quite sure, the Sony and Nikon 70-200mm f4 are quite a bit better than the Canon one, and I am sure Canon must update it with better IS and better anti-flare coating very soon to be competitive. the Nikon has almost 5 stop effective VR , and it focuses very very close, so personally I do not buy the Canon f4 70-200mm IS lens now , and I do not need f2.8 any more in this range(I use the Zeiss 135mm f2 APO instead). So if I need the best 70-200mm f4 zoom now , I will go Sony or Nikon. If you can wait , wait a few months , I am quite sure we will see a new 70-200mm f4LIS lens from Canon at Photokina(it does not mean we can actually buy it very soon , though).
All that having said , the best 70-200mm zoom is the Canon 70-200mm f2.8LISMK2 USM lens.
ATC, this is a phenomenal lens, you won't be disappointed with it.
This lens is ALMOST as sharp as the 2.8IS version.... They are so close that with the lens to lens variations one would expect to see, they almost certainly overlap. It is a phenomenal lens, quite possibly the best " bang for the buck" of any canon lens. You would need laboratory testing with test charts to tell the images from the F2.8IS version, yet at half the price and weight it is a lot easier to afford and much much easier to carry and to operate. That extra 2/3 of a stop comes at a big hit in weight and dollars.
I have had 3 copies of the 24 L II and I was very impressed with the feel of the lens and except the lens hood, very nice build quality. But that's it. I didn't like it at all IQ wise and AF was absolutely useless.
May I ask what you did not like about the IQ of the 24 L II?
Yes you may! Mine wasn't very sharp, both because of AF issues and I didn't have a great copy, it had annoying CA. The things I liked about it was the 1.4 of course, superb color and good contrast. But I always liked the 35 L better for AF and focal length. If I had one with the AF as good as the 35 and sharpness to match I might like better.
OK, thank you. I also own a 24 L II and I find the image quality amazing. Admittedly, the AF could be a bit faster, but it focuses very reliably on my 5d, even at f/1.4 without AFMA (which the 5d does not have). I guess I had luck with my copy.
The Sony sensor is very good, but if you exposure the Canon optimally the difference is generally academic in the vast majority of circumstances. However if you have no understanding of exposure the exmor is better.However, filter manufacturers sell loads of 1-3 stop GND filters so a couple more stops of dynamic range is useful to a lot people as well, even people who understand exposure, or should I say, especially to people who understand exposure.
Which is fine for photographs with a split horizon, What of trees extending in the darker area of the graduated portion of the frame? I used to be a big GND filter user, but I prefer using a combination of shots to balance exposures across a frame. I don't like GND's because I can usually see the GND graduation in the frame which points to a poor methodology to control the contrast in the first place.
Those people will know that by using a 1-3 stop GND you are able to get more light to the non ND part of the frame, which, depending upon what you are shooting, results in improved data from dark areas whether you are using a 12 or 14 DR capable camera. So you probably have as many Sonikon photographers buying them as Canon.
the thing I find the most funny is that where talking about this because nikon messed up and made 2 bodies that essentially do the same thing and now have to consolidate those 2 into 1 body totally screwing all those who bought either body over....
meh, it's not totally screwing anyone over. Everyone who bought the D800 knew what they were getting. Likewise with the D800E. Chances are many of them have netted some spectacular images with them over the past couple years. Nikon releasing a marginally better model doesn't affect anything excepting maybe resale value.
Well, I guess if your used to a company that updates high end stuff too quickly then no, it isn't screwing folks over it's just good training to never buy their new products because it'll just be upgraded within 2 years anyways.
