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. For those who missed the announcement: http://www.canonrumors.com/2012/09/samyang-24mm-f3-5-tilt-shift-announced/

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.

Lenses / Re: Canon EF 28-135 / EF-S 17-85 / EF-S 15-85

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.

This might be a good place for me to bring up something I have often wondered about. Do manufacturers ever slip in unannounced updates to lenses? I have to assume they do even if it's only firmware. Is there a way to tell? I like the idea of Sigma's newly announced usb dock lens cap for firmware updating lenses.

Any chance a brand new Sigma 50 would have more accurate or faster focusing than one from a few years ago?

342
I owned the Sigma and really liked it optically, but wasn't happy with the focusing speed (5D Mk II). I sold it for the Canon 1.4 and am very happy. Here's a shot taken with the Canon on my 5D MK III in natural light at f/2.

Lenses / Older L lens repair 400mm 2.8L II (non-IS)
« on: October 02, 2012, 01:41:28 PM »
I own the pre-IS 400mm f/2.8L II and see that it is not listed on the CPS repair eligible list. My lens is working great at the moment, but I am concerned that if the USM fails or something else goes wrong that I am going to have a very expensive paperweight. I am considering selling it while I can.

Does anyone know where I can get it serviced? Parts availability?

EOS Bodies / Re: Canon 5D3 vs. Nikon D600
« on: October 01, 2012, 12:49:22 PM »
5dmk2 and d800 same exposure time, f-stop base iso
5dmk2 developed in camera raw and DPP and d800 in camera raw so that details/information can  be seen equally in the white  house wall and in the white  towel  in front of the garden house =high lights reproduction.
Then we look in the shadows, low levels , an area is selected in the low levels and auto contrast is laid, auto contrast are showing  levels , details, noise in the selected area , no personal influence , photoshop is calculating  the signal level from the pixels values. This is the  results of  2-3 extra stops DR  in low levels.  And how to use it- it is up to the photographer and  the skills to use photoshop
PS
I have lent the  raw files to a number of talented members at dpreview , they  have  all checked  and verified the results by them selves.

Great comparison of noise at 100% scale vs. 66.7%!

I've seen good advice about what to try in the future, but regarding the photos you've taken...if you drop the exposure all the way on the RAW file is it possible to get the faces to look decent? If so, you might try double RAW processing the image in PhotoShop.
