OFFICIAL : 5DS and 5DS R Announced

BTW, Nikon has always had T/S lenses that are priced similarly to the Canon equivalents. Just not in as may focal length varieties. http://www.bhphotovide​o.com …de_Angle_PC_E_N​ikkor.html

It's not that they don't have them.

It's that the Nikon PC-E 24 is crap.

Oh, didn't know that. I've never shot with it. I'm telling you, all the more reason to stick with Canon and work around the DR issue with the new aR7.

That's what I'm currently doing - using an A7r for anything that doesn't move, and intending to get the 50MP Sony once it comes out. Am also considering a 5Ds specifically for wildlife photography, to go with superteles (since DR isn't an issue for Canon once you're shooting ISO 800 or so). But I'd like to have a system where I could actually use lens correction profiles to get rid of CA, which tends to be quite noticeable with high-resolution sensors even when using the best lenses, as well as distortion. Such profiles exist for Canon lenses on Canon bodies, or Nikon lenses on Nikon bodies, or Sony lenses on Sony bodies, but not cross-platform.

Lens profiles work fine with Canon-mount lenses on the a7R in Lightroom. They do not work for Nikon-mount lenses on the a7R because the adapters do not transmit the lens EXIF data to the camera or raw file.

I don't use Lightroom - I use the Sony RAW converter and Photoshop. Lightroom just doesn't have the masking tools I need, and Sony's Image Data Converter does better with Sony's RAW files than Adobe's converter.

Where can you get profiles for Canon lenses on the A7r? Also Sigma/Zeiss lenses.

In the lens tab, you manually select the lens you used. Usually all that is needed is to select the manufacturer and LR will automatically select the lens. But, sometimes overriding it is necessary. For instance, when I select Zeiss, it sees my lens focal length is 55mm and correctly selects Otus 55mm, but it defaults to the Nikon version. However, the Canon-mount (ZE) version can be selected from the profile list manually.

I use Lightroom just for intial raw conversion with lens and camera profile corrections. But, I do my main editing in Photoshop, so I have no need for masking inside Lightroom. The Lightroom to Photoshop exchange is seamless.

I haven't tried the Sony Converter. Is it really far better than ACR? I have seem people claim that other converters (like Capture One) are better just because the default settings look poorer in ACR/Lightroom; but I never work with default settings. I typically use my own custom color profile calibrated to my a7R, so my colors and tones are accurate.

You have me intrigued: I'll give the Sony converter a try...

[EDIT: I downloaded/installed the Sony Image Data Converter and right off, I can see what you mean. Quite a bit better than ACR at first glance. Colors and shading look very good. This is a good addition to my workflow.]

Tilt-shift lenses are used more often in architecture and product photography than landscapes. They just also happen to be useful for landscapes.

If they were actually intended for landscapes, they'd come with a tripod foot, to allow for shift-stitching without moving the lens around.

The fact that they don't have tripod feet is one of the reasons I have never bought one. It seems absurd to me to shift the lens, instead of the body. Shifting the lens is not the same thing as having an elongated sensor; only shifting the sensor is.

I bought a separate tripod foot for it.

That way, the lens stays still and you shift the sensor within the image circle.

That said, in most situations (except where subjects are very close to the camera, relative to the focal length) the parallax is minimal and doesn't cause any artifacts when stitching.

Wow! Thats great, especially because the 24mm TSEii is very heavy on the A7R...

But for 500$ he can kiss my ...

I'll probably get one of these ( $500 for a lens collar seems outrageous, but $500 to turn your camera in a 2x MP sensor does seem reasonable if you need the MP - so a 50 MP 36x24 becomes ~100MP 36x48 or 24x60 if you push it all they way. There are 4 Canon T/S lenses and you can use a 1.4x, so the versatility is good - There, I just convinced myself). I wish he had designed it so it could do rise and fall as well as (lateral) shift. Given the way the collar attaches to the flat sides of the lens they must always be vertical. So you need to tilt the tripod head 90 degrees to do a vertical stitch, right?

Yep, you need to tilt it 90 degrees for a vertical stitch. But, for a typical landscape, you won't encounter parallax errors when doing a vertical stitch anyway (since the joint between the two frames is usually way off in the distance) so I generally don't bother with the collar when stitching vertically.

Alternatively, I think there's now another collar available that allows for vertical shifting. Not sure who makes it, though.

Most of the time, agreed. I recall a few shots where the mostly bare branches of a big tree were close and distant and no stitcher could get them right after shifting the lens only

Another collar? We need a collar that itself rotates. Tell me more!!!!

Can't remember who makes the other one, though.

With the Hartblei, you can also attach the quick-release plate to the side of the foot, rather than at the bottom. This means that you don't have to tilt the head itself to 90 degrees - you merely mount the lens foot sideways in the clamp, so that the tripod head itself is upright, but the collar and foot stick out at 90 degrees to the head rather than on top of it.

I have heard that only the highest quality lenses will be able to fully utilize the 5DS(R) 50 Mp sensor. However, this may only be conjecture. I'd hate to spend a fortune on expensive lenses that I already have EF (not L) lenses. Is there any truth to this? Thanks.
