Well, neither of these are "walkaround" lenses. They're specialty tools...and manual focus. You can do some interesting things with them. I've seen wedding shooters use the tilt effect in cool ways, but the real beauty of these lenses is in slower tripod work.
Something to consider, and in my opinion a must have for a shift lens, is a geared tripod head. It really helps me to have the axial control to adjust the attitude of the camera with the shift movement to keep your lines straight.
My preference is the TS-E 24L II. It's just a miracle of engineering, and for me it yields a more natural perspective. If you need more width, you can quite easily stitch frames and get even more than a 17mm FOV.
Yes, Sir, Dear Mr. dryanparker.
You are right " the real beauty of these lenses is in slower tripod work. " = 100% right.
Yes " They're specialty tools...and manual focus. "---Yes, I solve the problem of this Awesome Manual Focus---By set up the one center spot Focus at my Canon 5D MK II, and set up the Loud beep sound when I use my old hand turn the Focus ring---Yes, If it at the right Focus when , I turn the ring, The Canon will beep, And I will stop at that point, and move the camera to the best point of view, and shoot the photos.
Yes, It Slower than AF, But That the best way for my 64 years old eyes.
And for walk around condition in day light time, I just set my F. Stop at 8.0 and Set the Focus at Between 5 Feet and Infinity , or 3 Meters and Infinity= I will get all perfected sharpest pictures in every times , with out adjust the focus ring------Ha, Ha, Ha, But I must tape the Small piece of duct tape on the focus ring, to make sure that It not accidential move/ rotate , during I take the Shot.
Nice to talk to you, Sir.
