I was looking through a few pics a friend had taken. When I peeked at her EXIF data, I remembered something I never thought of. Hope that last sentence made since. My language doesn't translate into english very well. It had "Canon EF 80-200mm f/4.5-5.6" listed as the lens mounted even though it was a Tamron 70mm-300mm set to 300mm. Would the camera or other software being used take that information and apply false adjustments to compensate for issues that the EXIF says it is rather than the lens that was really on it. Taking it kinda to an extreme, doesn't the camera sense/communicate when a wide angle lens is on and "thinks" about what your trying to take a picture of (ie landscape), even though it might really be a telephoto lens for bird shooting? It prolly isn't that important when shooting in manual or with RAW files. That takes all the "camera guessing" out of it I think. It just seemed odd, especially when it read out the correct focal length of 300mm, but insisted on 80-200 lens. Any thought?
