wide angle pano tokina 11-16mm

[togish1]

hey everyone...ive never really tried to do any pano shots, but i would like to do one on my trip to PA next month. I have the tokina 11-16mm 2.8 and i was wondering what focal length i should be shooting. If i shot at 11mm would i have issues when stitching? and if i did shoot at 11mm, what percentage would i need to overlap?

Frankly, almost any focal length that lens is capable of could cause problems. The problem is edge distortion. You may have to overlap the images rather severely to get good seams. You are really better off using a longer focal length lens and just taking more shots - and it may not even require many more because you won't have to overlap them as much.

Whatever you do, if you use the Tokina make sure that you have the camera dead level when shooting, or the convergence distortion will just about kill any chance of a good stitch.

This is a pano stitched from four images at 24mm focal length (17-40 f4 "L" that I used to have) taken with a T1i.

Shoot in portrait orientation...

Forces the worst distortion into foreground you can crop and in sky where it won't really show. Stop down some and that will help stave off light falloff in the corners.

okay so i went out and tried a pano shot...this was done with my tokina 11-16mm @ 11mm and photomerged in photoshop....im convinced i can do quite a well pano...this is a 10 shot pano, done without a tripod...just sat the camera on top of the bench and moved it on a pivot....not bad at all....cant wait to actually do a great pano with this lens...this was also shot in landscape orientation, not portrait, i will try that out as well

You've got a very clear horizon there so you could have also shot this hand held.

what do you mean by that?

okay so for anyone who said you cant do a pano with this lens is wrong...6 shot pano @11mm in portrait orienation

The only difficulties I've had with panos are moving trees and objects close in the foreground. The latter being the real problem (I don't have a pano head).

Wide angle lenses can be nice because you might be able to get one shot for the near foreground and not have parallax errors, but the chances of something else going wrong are a bit higher. I'm still not sure for really wide panos (say 180+ degrees) what the optimum FL is. I usually go wide because I don't have the patience to take 20+ shots.

i know what you mean, its not easy stitching them together, it took me almost 2 hours to put this together

I don't think that anyone said you can't do a pano with it, only that it can be difficult, and you found that out by taking 2 hours to assemble it. Some of the difficulty probably came from the subject matter too.

Wow. That is awesome. I went to Flickr to check out the exif, but there's not much there. Do you mind sharing what ISO, speed and aperture you used?

ISO 6400
30 seconds
f2.8 or 3.2

I think you really made this lens shine in a new way. With your Six pano shots how much over lap did you give yourself? Any any other insights into your process would be appreciated.
