What is best lens to take panoramic type pictures?

I have 12-24 and 24-135 mm lenses on a Canon 20D. What focal length is best for large landscape type panoramic pictures? Is there a better number of shots to take for easier stiching?:? I would think the superwide lense would cause distortion at each edge making stitching problematic.

I tend to use my 17-40L lens. I use Autostitch and find that 3 shots are usually best for stitching.

Here's a 3-panel shot of my daughter's house in Malibu.

BTW, I used a 20D as well. Without checking I'm thinking my focal length was somewhere between 20-24.

I'm not sure the exact focal length matters, just be somewhere in the middle of the zoom range. There tends to be barrel and pincushion distortion at extreme ends of lenses. Some stitching programs can correct for this if you enter the focal length.

ePaperPress has a very useful utilitythatcorrectsall sorts of lens-related problems. It's called PTLens.There are profiles for many lenses for most major dSLR cameras. Check it out at:

The odd thing about picking a focal length is that you can make a given lens "wider" by using the camera in vertical orientation instead of horizontal. This pano was shot with 50mm lens on a D70S, which is normally considered telephoto. But because I used it vertically, and made around 11 or so exposures left-right, it actually has awide anglefeel. This is a single row image, but if I cared to take another row of images just below or above this one, it would be wider still. I know several panoramic enthusiasts whoworkwith 100mm to 150mm focal lengths on DSLR's, and just shoot and stitch a lot of images. It seems surprising that such long focal lengths should work out, but panoramas are different...

Stitched panilessly with Autostitch.exe, one heckuva good program!

That's a lovely pano/composite. I, too, really like Autostitch.

I find 50mm Lens, with 15% overlap on each pictureand the camera needs to be horizontal from side to side and back to back.

when taking this panoramic picture, the camera need to hold by tripod? need to move the tripod position or fix the position and just turn the camera?


thanks
