Tokina 11-16 lens profile-download question

Question

Lens profile downloader_p3_102510.air  then clicking on this did not produce any results ....although AdobeAir is on the hard drive ...so I downloaded on 7/12 the AdobeAirInstaller so it might be that my air version is old since its a version 1.## and this download indicates a higher version.
So the only way to download a lens profile is with this downloader ?    OR
lensprofile_creator_p3_win_042711.zip  Does this have the capacity to view shared lens profiles and download?
Does this downloader go automatically to the storage location and produce a list from which to choose?
The Tokina lens arrived yesterday along with a 7D and I didn't value the lens profile corrections until I had to adjust a wide view of a building, one of the first test shots.
I have to admit I'm a little nervous about the above installs and then searching for the lens profile download . Its likely the AIR feature since in the past I did get errors in the event log connected with AdobeAir.
I guess I'm double checking on routines that others have used.

Answer 1

I cannot figure out how the download is to begin. I have clicked on Download....the bar fills with a colour and no file arrives on my hard drive.
You need to click on the gold box near the top right of the screen that says 'Upload file.' You will be prompted to create a "free account."
OHho...factory built in tilt....is that so?....I have wondered about that because its just TOO consistent and I have lined up with an object on occassion. Good info to include the tilt into the preset.
Shoot a picture of a window frame that nearly fills the viewfinder and make sure it is perfectly lined up on all four sides. Using a tripod helps. If you see a tilt, then you have the factory assembly defect of a "tilted" viewfinder image. Don't be surprised if it is also a little off-center! My 300D viewfinder is tilted clockwise and to the right slightly. Canon repair may be able to adjust it, but since it was so slight I never bothered.
AND specifics according to the camera serial number... I haven't had to deal with that to date but I have read about it,so its good that the code refers to the camera serial number rather than having to make specific settings.
Please read my correction note – There is no need to do this unless you own two of the same camera model and need to set the defaults differently for each.
I've just used the Jao, Nikon profile on a few Lake Huron sunset shots and a slight correction was made but I still had a tilt ....the lake was running downhill to the north <grin>
You are confusing "rectilinear distortion" such as "barrel" and "pin cushion" distortion with "perspective distortion!" ALL super wide-angle lenses can exhibit significant perspective distortion in different shooting situations, which can be very useful for "creative effects." Vertical perspective distortion is created when the camera is tilted up or down, and Horizontal perspective distortion is created when the camera pointed left or right of a central object. Go into Lightroom Develop module>Lens Correction>'Manual' and move the 'Vertical' and 'Horizontal' adjustments. This applies digital image processing to "correct" your picture, similar to what an expensive tilt-shift lens does on-the-camera
Even when you correct your picture elements for "parallel" vertical and horizontal lines, a super wide-angle lens may still exhibit what appears to be a "distorted perspective." That's both the virtue and deficit of shooting with short focal length lenses – It's up to you to properly apply this creatively to your subjects….but that’s a whole other subject!
