EF 24mm TS-e II - question about tilt.

With the camera horizontal and the lens' shift function also horizontal and shifted fully to the right, how do I tilt the focus plane diagonally from upper left to lower right? The tilt function only rotates 90 degrees and no matter how I try it can only tilt upper right to lower left. I've tried rotating the shift function 180 degrees as well, but the result is the same. The only thing I can think of is to rotate the camera 180 degrees, which is unacceptable. Any ideas?

(From Canon's user manual...)

This is what I would have suggested.

OK, so you got me out of my seat to check.

Yup, I think you care correct, you can't shift horizontally and tilt in that direction at the same time. I guess I've never tried to do that in the years I've had the 17mm. Never heard anyone complaining about the restriction either.


Or maybe I'm having a brain fart, but I don't think so.

Lol. I have yet to take a picture. I'm setting up for the first shot and I just happened to pick the angle it won't do. Go figure.



Thanks, Edward.

You can tilt and shift in the same direction, that's what the diagram above is explaining.
ie, next to the ! "When tilt and shift are used in a parallel direction"

When not in the same direction (parallel), they call it "right angle".

The diagram is also saying tilt and shift can be used diagonally, ie Case 3 in the vignetting tables.

Yea, I think that is the one combination that does not work, you would have to mount the camera upside down, as you suggested.

I can see a use for that combination though. I'm sure I have used horizontal shift and near-vertical tilt along a wall. I guess my tilts were probably exactly horizontal, but I can see why one might want a bit of tilt in that (tilted) direction.

I'm also somewhat surprised since I always had the impression one could shift and tilt in any orientation - without mounting the camera upside down. If someone had asked me, I would have said yes, without really having tested it.

Interesting. It's obvious that it's like the OP says, you can only do a tilted tilt (!) in one quadrant. But my TS-E 24 mm f/3.5L II is the opposite, i.e. will shift horizontally in combination with a tilt from upper left to lower right.

I haven't tried this, but I dare say remove the four screws, one in each corner, of the bracket holding the front part of the lens. Rotate the lens 90° and set the screws back. Now you are equally limited as before, but in a different quadrant. That is, now you can do what you want to do, but not what you used to be able to do.

This is similar to what you had to do with the older series of tilt-shift lenses from Canon. There you couldn't easily change the fact that the tilt was perpendicular to the shift. You had to partly disassemble the lens, rotate the front segment and assemble it again. Then you could get shift parallel with tilt. To go back, you had to disassemble it again.

I had though about the old TS-E, but forgot to look to see if there were screws in the new ones.

Yes, my 2 TS-E's tilt upper left to lower right with horizontal shift, I assumed that's what Olivia meant.

She says she wants that (upper left to lower right, or like this \ ), but her lens does only the opposite (upper right to lower left, that is / ).
By the way, flipping the camera upside down will not help. It will just rotate the whole movement 180°, but that means it still runs along the same axis, just upside down. You have to rotate the camera 90° to get the tilt in the desired direction, but then the framing is in the wrong direction.

Good point, I should have realized that.
