Yes, I use ACR corrections to make vertical lines vertical. Most of the time it does great, and for the most part I am posting my travel pictures on my web site, so the loss of resolution is not a problem.TS-E lenses are great for architecture, although mostly that's shift. If you're close to a tall building, pointing a regular lens up causes keystoning (the building looks trapezoidal), but keeping the camera level and using shift keeps the vertical lines vertical. Here's an example of the exterior of the Cathédrale Saint-Gatien de Tours, the image on the left is not mine but was clearly taken with a standard lens pointed up, the one on the right is mine with the TS-E 17 and shift. Software correction for keystoning has gotten pretty good, but since I have TS-E lenses I'll stick with the optical correction.
I rented the 24mm TS-E first and did well with it. I found that the 17mm was harder for me to learn to use, and I didn't get very good in the short time I had it. Interiors in my house looked almost like something out of Escher. I realize that there are real estate photographers who use it all the time, so with a lot of practice I might get good at it. If I purchased one of them, it would definitely be the 24mm. The 17mm for me did a great job for stitching. I couldn't have got the whole building in the picture below with just one 17mm shot. If I moved back, trees would have been in the way:
There is a bit of distortion on the right I could spiff up in Photoshop and maybe touch up verticals on the left, but for a quick experiment, it is not bad. The reduction for the web seems to have lost a lot of sharpness, too, but you get the idea.
I used the tilt more with the 24mm. I made pseudo-Ansel Adams shots such as one with everything from a rock near a leg of the tripod to a waterfall fountain in that park all in focus. I then converted it to black and white and printed it on my printer that has black, "light-black," and "light-light-black" ink cartridges. A park in my neighborhood was as close as I came to Yosemite during our COVID lock down.
