Wow the f2.8 Image (and even the f4) of your copy looks bad... I hope its just calibration.

After the pancake being so sharp at 2.8 there is no excuse for that lens being that soft. I mean its f*ing expensive...

If you look at the 5.6 image out of the 5d you notice that the extreme edges are a bit soft. And thats not nice for that price if you look at what the shorty fourty does...

while the f2.8 shot of the fower does seems a bit soft, I would not make decision based upon a close up shot test. It is not a macro lens, and it is not unusual that a non-macro lens behave sub-standard in closeup. The 17-55 2.8 IS USM is a good example of a very good lens that behave poorly in closeup photography.
Make some more test with more distant subject to see how the lens behave in its native use.

2.8 isn't pretty. My 40mm Pancake blows it away.

Take a few more shots to rule out focus error.

I only posted the flower images because they showed the poor IQ at 2.8 compared to 4 so clearly.  I did lots of shooting at various distances.

No this wasn't just focus error.  This is representative of what I was seeing with all the images I was taking.  My 15-85mm at 24mm and f/4 is even a tad sharper, so this new lens gives me nothing I don't already have in my bag.  Back it goes.

This lens is good and all, but I just dont see a solid purpose besides video.

Taken with 5DII @ 1/160 f5.6 iso50, resized to half with DXO.

can you post a full, non-resized image like that at f/8?

that looks quite promising edge to edge, but with half-resize you can't really tell much, it could be blurring 2 pixels into 1 for all we know

Your 15-85 at 24mm f/4 is sharper than the 24 IS at f/4? Or do you mean the 15-85 at f/4 is sharper than the 24 IS at f/2.8?

Sharp corner to corner (or so one would hope  ;D) landscape lens for FF at less cost than 24 1.4 II or 24-70 II (or 24 T&S II while also being a bit more quick and ready than that one) that also has IS so, for the times, when you don't want constant tripod work slowing you down and becoming a bother you can still get some nice snaps along the way?

Anyway that is what I'd look to it for.

I meant the former, but also the latter is true obviously.
The lens did get returned and I tried the new 28mm with disappointing results.  In fact my results were the opposite of LensRentals quick review.  The 24mm sharpened up from f/2.8 to f/4 but didn't sharpen all that much after that.  The 28mm, on the other hand, was softer at f/2.8 than the 24mm, sharpened up at f/4 and sharpened even more noticeably at f/5.6.
I would like to try different copies of the new 24mm and 28mm, but I'm not so sure the camera store will let me back in  ;)

17-40L is more of a landscape lens that this prime for about the same $$$.
