Exif data that shows what brand of lens was used?

I was shooting with three different copies of 24-70 (canon, sigma, tamron) and when viewing exif information I can only get the mm of what i was shooting but not the lens brand. Is there any program that allows me to see the brand as well?

What are you using to view the exif? I believe Lightroom shows the full name of the lens, including maker.

flickr seemed to show the brand. listed like this "Tamron AF 17-50mm f/2.8 Di-II LD Aspherical"

PS CS6 and Light Room do. Canon ZoomBrowser that comes with your camera gives a very complete Exif, though it is also a factor of whether the camera body reports the info. I know my 5D3, 5D2, 5D and 7D do report, but the old 20D doesn't.

i believe that i tried dpp and ps cs5. Maybe the 50d doesnt record that info? I will need to dbl check

zoombrowser and my 40D don't show the lens used...however, like mentioned above flickr does
