You mention excellent build quality...can you post a picture or comment on the gap between the focusing barrel and the outer lens body? I'm taking about the barrel that houses the front element and moves in and out to focus. On the copy of this lens that I owned, I found the gap to very large and I quickly got dust inside the lens. It settled on the inside of the rear element, where it is actually a problem. Fortunately, the rear element is easily cleaned by taking the lens mount loose (which houses the rear element) and puffing some air on it.

I cleaned mine, verified it still functioned perfectly and then sold it.

As far as i know the IPS panel in that monitor is only 8-bit.

Edit: it is 8-bit with ARC for an emulated 10-bit, but either way the pro workstation cards are well out of the price range.

Where did you find that this is an 8-bit panel?

The ATI v4800 is a workstation card for $160 that outputs 10bit color over DisplayPort: http://www.newegg.com/Product/Product.aspx?Item=N82E16814195096

Wow, had no idea this was possible. Now I have to go back and read the AF guide in its entirety.

Love the Grand Canyon shot. I owned the 90mm TS-E for a while got a few nice pictures, but wished I had bought the 45mm or 24mm. I still think the 45mm might be the best choice for me. I'm really hoping the Samyang 24mm is as good optically as their 35mm and is priced reasonably.

Imagine a picture of a little wildflower filling one side of the frame with a field and stream in the midground and the distant mountains in the background...and all of it in sharp focus except for the grass right underneath the flower with dreamy bokeh.

That sounds like you're speaking from experience. I'd love to see it. It might put me over the fence on buying one.

I like the format and the subjective take. For something specialized like T&S more samples of what can be achieved would be helpful who is new to the concept.

I would also like to see this updated if you review the Samyang when it becomes available.

I used mine with the 24-105 in moderate rain for a couple hours with no problems. I'm sure the rubber seal at the base of the lens makes all the difference in the world.

If we consider that the shape of today's DLSR was inherited from their film forbearers and ask what can the shape be when no longer constrained by roll/sprocket/spool assembly...I think it's an interesting question. I think the overall layout must be pretty similar. I guess I would like to see the grip, LCD,  and controls separated from the mirror box/viewfinder/lens mount so that the one can rotate 90 degrees to the other to allow for portrait or landscape orientation without the need for a 1D-esque tall body.

In other words, my right-hand never changes, I just use my left hand to rotate the mirror-box piece. That would be neat.

On my recent trip to Sweden I shot for two hours in the rain with my 5D Mk III and 24-105L. No problems at all.

I'm surprised to hear the 7D had water behind the LCD. What lens, if any, was mounted?

Roger at lens rentals has opinions on these lenses that you might find useful. Apparently both the Canon 1.2 and Sigma have AF quirks that fall into repeatable patterns.

See Roger's Take:

Canon 50mm 1.4 : http://www.lensrentals.com/rent/canon/lenses/normal-range/canon-50mm-f1.4
Canon 50mm 1.2L : http://www.lensrentals.com/rent/canon/lenses/normal-range/canon-50mm-f1.2l
Sigma 50mm 1.4 : http://www.lensrentals.com/rent/canon/lenses/normal-range/sigma-50mm-f1.4-dg-hsm-for-canon

I got a 5D Mark III last week and the first lens to undergo focus testing in my studio was that Sigma 50.  I was relieved to see that it now focuses faster and more consistently.  I think I dialed in +2 on the micro-adjust.  Images were pretty sharp wide open and extremely sharp at f2.0.

It's statements like this that make me wish I hadn't sold mine before my Mk III came. I really would like to see what difference the body made.

I've not used the 15-85, but wanted to give a strong endorsement for the Sigma AF 17-50mm f/2.8 EX DC HSM OS. I loved it when I had a 7D. My brother gets a lot of great shots with it now on his 60D. The image stabilization is nearly silent which is great for video. The corners are soft at 2.8, but the center is really sharp.
