Canon Tilt Shift Lens - 24L, 45, or 90

This is downright lame advice.

You must be the only person to take this seriously.

It's hard to make an acceptable wideangle TS lens, I could explain this, but it would take quite some time - just trust me.

I don't trust you, please explain it.

I voted for the 90, which I own, and use for portraits and macro. One of the sharpest lenses Canon has ever made. I thought about the 24 and 45 but some reviews about their IQ trouble me. I just ordered my next TS lens the Canon 35/2.8 TS. Has a reputation as the sharpest 35mm (focal length) TS lens ever made. Yes, I am having it custom altered to an EF mount.

Good. I was just about to ask you what you were smoking.

Love to see some T/S shots. We don't see enough. I think they're quite the intriguing set of lenses.

I would also enjoy seeing some T/S shots.

Ok, here's some low resolution samples with the 90 TS-E at f/4.

I see what you mean about the DOF --------- Thanks

How useful would a 90mm TS lens be on a 1.6x crop body to shoot a high building from across the street? Or a tall medieval church 20 meters away from the central gate?

I don't doubt that the 90mm TSE lens is much better optically and that a 24mm TS lens is a challenge to make. The issue is - as I understand it - that TS make more sense to a wide angle.

Yeah, while I don't have a T/S lens myself, my brother has one with his Nikon system (28mm that shifts only). I have used it several times, all his SLRs are film. I have shot trees and buildings with his camera/lens and I really don't think I would like a lens any longer of a focal length with a perspective control, regardless of 1.6, 1.3 or FF format.

Get the L

On FF, I think I'd prefer the 45. Kind of an "all around" lens. Architecture, close-up, portraits, landscapes, etc. The L (24mm) just gets the worst reviews of the three. I'd be the last of the bunch that I'd pick up.

The 90 is much better optically than the L 24mm TS lens. Its so stupid to have a red ring around the TS lens which that has the worst reviews in optics out of the 3.

I have no idea why the TS 24L is so popular, I think its the red ring that makes people want it over the others.

I think from this thread the TS 45 seems to be the "all around" winner. But I still want the 90 since its optical IQ seems to be top notch.

Do you think the TS 45 would work well for product photography on a FF or 1.3x Camera? I much rather have the 90, but again id screw myself for taking shots of big things lke buildings. Even thought product and portrait would be its main use.

One a 1.6 body this won't work well. You're using a 144mm effective FL so it's a telephoto pretty much. Obviously if you can back up enough it will work but I'd bet/guess the 45mm or 24mm would be a better fit.

Take a zoom outside, and look through it and see what FL frames what you want to shoot the best, 24, 45, or 90mm and that's basically what you need. You'll just shift to get everything straight.

I got the 90 for close ups but think its also fun for interesting DOF effects (see attached - no PP!)

I really recommend you know what you're gooing to do with it before you buy one.

the 90 would be incredible (semi) macro on a 1.6 crop

EDIT : been waiting for over 15 mins for the pic to upload so there's something wrong there - will do it laterer

The 90 TS-E made it to number 5.

Haha I did not take this seriously, but I've seen people buy the 24 version because canon calls it L, and those people immediately think this is the one to go for. It's sad, but it actually happened. This lens is has the L designation because prior to this lens, people might have considered a useable tlit-shift 24mm retrofocus (SLR-) lens would be impossible to make.

Thanks.

I don't have the time to go very deep into it, but by design, wide-angle lenses show quite some vignetting at large apertures. This can be seen clearly on the 24/1.4 and 16-35 MkI on full-frame. Of course when you shift such a lens, vignetting becomes hellacious soon. This is nearly impossible to fix.
Read this page: http://www.vanwalree.c​om/optics/vignetting.h​tml and have a look especially at fig. 2. This pic says a lot, the page (almost) tells you everything else.

For the same reasons, most real telephoto's (>100mm), even the cheaper ones, have very little vignetting, and a very even sharpness across the frame - wide open, too. Like Marsellus said: alas, this is a hard moth......ing fact of life.

Because WA-lenses for SLRs have a very high level of refraction, they easily lack sharpness in the corners/along the borders of the frame. The same as with vignetting, this becomes annoying quickly when you shift the lens.

The 24 TS-E does very well in both aspects, especially stopped down. It's almost a miracle that it's useable full frame, shifted, wide-open.

Tilting of course is not that much of a problem.
