Here is my contribution for today, a quick 'product' shot of an EF35mm f2 IS taken with the TS-E50, first one is no shift or tilt, second is with tilt and shift, both f5.6.

Tilt-shift techniques and lenses
- Thread starter stevelee
- Start date
Here's one from the TS-E17,at f9.0, I love that the deck of the dock is pin sharp all the way through and that focus extends to the far shoreline, TS-E's take you from 'acceptably sharp' to pin point in focus, I don't understand why more landscape shooters don't use them, well I suppose I do, few people output to any kind of size nowadays.

And another from the TS-E17 at f10 again with tilt to control the focus through the picture, the cobweb was around 24 inches from the lens yet the trees in the fig are perfectly focused.

Do you by chance have any links to sites/videos explaining how doing the tilt/shift thing works for moving the plane of focus, etc?
I don't have a TS lens yet, but I do have a new MF View camera (6x17).....which has all the tilt and shift movements TS lens would have....so, I'm interested in learning the principals of this, how and why it works, etc.
When you are shooting this and tilting and shifting, are you just moving things around while you look through the viewfinder till it all looks good to your eye, or are there any distance measurements and formulaic calculations you would be using (too) ?
Thanks in advance,

Hi Cayenne.
A quote from PBD in the waterfalls thread.
“Have you read Kieth's articles?
This one is about using an iterative approach to focus and tilt http://www.northlight-images.co.uk/alternative-focus-technique-for-tilted-lens/ It takes a lot longer to read than do!
But he has loads of articles about using tilt/shift lenses and reviews of all seven EF TS-E's, first class resource for everything tilt shift, and printers and a ton of other gems. http://www.northlight-images.co.uk/category/articles-and-reviews/tilt-shift/”
Cheers, Graham.

I shot a few pictures in a small park at the end of my street. There is nothing spectacular in these that demonstrate much about the tilt-shift properties, though I used both in making the pictures.

As Graham pointed out the Northlight links really are a goldmine, but the best nugget for your specific enquiry is these two gif's from Keiths site ( http://www.northlight-images.co.uk/using-lens-tilt-on-your-digital-slr/ ) but credited to Harold Merklinger, the brains behind the maths of focusing tilt/shift cameras and movements.
To understand how it works it is important to realize anybody who just mentions or eludes to the Scheimpflug Principle is missing the key element of how varying focus also rotates the plane of focus, but differently! The first GIF is the effect of tilting the lens and demonstrates the Scheimpflug Principle, the second GIF illustrates the 'Hinge Rule' and the changes to the plane of focus when you adjust focus, this is the key many people miss.Once you hear people using this stuff and referring to the 'J' distance you know they have a much better grasp of how it all works, that distance is from the lens center to the hinge line. Keith has printed cheat sheets for the various focal lengths, tilt angles and J distances.
If you really want to dig in the weeds Merklinger's two booklets are freely available on the web.
And there are other articles with the above GIF's and more of them https://lensnotes.com/articles/principles-of-view-camera-focus/

I haven't found anything by or from Canon that goes beyond a very rudimentary precursor into accurate T/S use, that includes their instruction books, videos, talks, presentations etc, indeed most of them I have found miss key points or further commonly held inaccuracies.

My playtime for the day.
TS-E 50 with full tilt, directly out of camera as attested to by the dust!

I decided to do some close up tests before I ship the 24 mm lens back. I used maximum tilt for all shots. For the first ones, I put the lens on a 12mm extension tube. The calculator didn't look that linty in real life, so the lens if very sharp. With the tilt, the closest part appears to get 0.55x magnification. Apertures are f/16 and f/22.

Then I took some shots without the extension tube. Maximum magnification for the lens is listed at 0.34, but with the tilt the closest part seems to be 0.42, so not really that different from that with the tube. For comparison, here are one shot at f/10 with the tube and at f/11 without:

That was not so rigorous a test, but enough to satisfy my curiosity. I've resized the pictures for posting. If anybody thinks they might glean some useful information from this, I'll be glad to post some 100% crops. Just tell me what you want.
Since the tubes were delivered this afternoon, I decided to try them on the lens. It rapidly became obvious that anything longer than the 12mm was not practical because of the short distances needed.
For my further comparison, I will later try the same subjects with the 100 mm non-L macro, with and without tubes. I expect the longer focal length and lack of tilt will give much smaller depth of field. I won't post those pictures here unless someone thinks that will be a useful comparison for them also.

The rented 17mm TS-E was delivered today. I haven't done much with it yet, just tried a couple of things. I shot from where I was seated in the den and used the tilt for focusing on the window beside me and keeping the fireplace reasonably in focus.
Then I tried putting the tilt and shift in the same direction. At extreme values of both, there is almost no light on the sensor, so I backed off a bit. I used the tilt to focus on the button on my shirt without plugging the distant objects too much. Even in this reduced version, you can see the detail in the cloth. Pardon my obesity.

Shot at dawn this morning with the TS-E 50, it's actually a two shot vertical shifted pano. May we all remember those active duty men, women and K9's who paid the ultimate price.
At this memorial the blue crosses are for active duty K9's and the yellow crosses for men and women who were lost to suicide on their return from theater.

I have about run out of things to try with the 17mm lens. I send it back Wednesday, and we are having showers off and on. I have to make a short video for the Episcopal church in my neighborhood to use Sunday, so I need to ge that done before I do much more playing around. The shoot itself is not that tricky, just me sitting by the window reading aloud. But the text is the original Greek of much of Acts 2, so I need to practice a lot. Also, without a haircut, I will need to work on my hair to keep from looking too much like Einstein on a bad hair day. I don't have an external microphone, but I don't guess intelligibility will be that important. I believe it will be part of a split screen with people reading simultaneously in other languages. Maybe I should dress as Charlie Weaver or Charles Nelson Reilly.
I took some shots on campus Sunday, including some panoramas and some outdoor artworks with the buildings. This is probably my favorite shot:
I did use some tilt and shift on the above to lessen the convergence. This is a more conventional view with the perspective straightened:
