After studying the details of Exif in Adobe Bridge CS5, I found that a few shows “no lens” on lens classification. Does this mean that there is no way for a user to know what lens was used? This is the case for Sigma, Tamron, and Canon lenses especially when the picture is taken in portrait mode.

Hello Steve Martin,
All that I know is that the EXIF data follows some quite loose standard, and therefore it is not very software and hardware vendor that agrees on what goes where when using this format. Of course the original EXIF data will be recorded by your camera whereby is will be saved either in the file on your flash card that you are using on the camera.
There is a possibility that a software that you are not aware of could have moved those files from the flash card to your computer. In this case you may have one opportunity to change the EXIF data, and then later the files will be processed either by raw conversion, editing, resizing and so forth.
You should not the Adobe Bridge specifically checks a single place EXIF data for lens information and it could be that some previous process may have re-written the EXIF data thus removing the lens information or possibly moving it to another location.
