Default Canon TS-E24mm f/3.5L

For those of you who have an interest, here are a couple of comparison shots using the 24mm TS-E lens. The location was Merrow Church, near Guildford. UK.

The first is an uncorrected shot taken from about 2ft off the ground. Whilst it is quite useable, there is a slight lean in the structures as the camera is pointed up.




This is shot from the same position, but with the lens shifted only 2mm. The verticals are corrected.



Whilst you could do this in photoshop, the editing would mean that you would have to crop the picture, there would also be some degradation as the pixels are stretched and compressed.

Nice comparison. I am going to add this to the lens image archive.

This is very true. I did some tests and found the MTF 50% value of a lens was reduced by 10-20% by using enough barrel distortion correction to correct for a EF 17-40/f4L at 17mm.

This loss of fine detail is very significant and corresponds to the difference between a very good lens and a poor one.

Thought I'd share some of a new favorite lens. If you want to get serious about architecture, this lens is indispensable. Any serious architecture photographer will tell you the same, there is no comparison with photoshop. Sorry.

This lens is just amazing, once you get the hang of it, its THE architecture/interior lens you will pick up. Period.





2 Shots stitched together, 22mp total.

Thanks a million for creating this thread. The 24 TS-E is my next lens (hopefully soon), and it's good to see some images from it. Thanks again!

Curse you! I have an Olympus 24mm Perspective Control lens for my Oly 35mm film system. I have a mount adapter that permits me to use my Oly lenses (many fast lenses) on my 20D; the FOV of 24mm on my 20D is frustrating after having used the same lens on film SLR. Curse you for pointing out the inadequacy of using APS-C and the need for 2x body cost in a 5D in order to get the proper FOV with that lens!

Hi!
I was suggested to add the following picture to the 24 TS-E archive, and this seems to be the right thread. So, here it is: Colosseum at Dawn, f/8, ISO 100, 13 seconds with an EOS-1D Mark II N.

Here is the last image my 24mm TSE w/ circular polarizer saw before I sold it. I hand held my 72mm polarizer in front of the lens... I had to rig it lol.

A potentially dumb question here:

When you shift the lens those two millimeters to correct the verticals, is it evident when you look through the viewfinder? I would think it would be, but just thought I'd ask...

Thanks! By the way, looking at the title of this thread, I remember that few days after buying the lens I posted a comparison between a shifted shot and a not-shifted one (of the same subject). You can see it here: http://photography-on-the.net/forum/...d.php?t=341694

Should be as one is looking through the lens. We often tend to forget this; if you've ever used a rangefinder camera (I have), the difference in what you see compared to an (D)SLR is startling.

I'm thankful for (D)SLR cameras.

No dumb questions, only dumb replies - hope mine wasn't.
