    At 1/1500th second, I could have been jumping off a bridge and still "got the shot."

    No, no tripod. This was a handheld trip ... the sling bag stuffed with three lenses and my external flash. Airline travel has become an absolute nightmare for hauling gear around with you. I pity people who rely upon it.

    Maybe "localized" gear rental (tripods, lenses, etc.) will improve because of this silly overkill on security. I know I'm just having to do without tools, accessories and extra equipment. Why not just wall the entire country off and be done with it? Oh yeah, that's go on down south, isn't it? My bad.

    Didn't know that. But like I said the AF is very fast and accurate. So yeah, it's got the AF

    No...let me explain.

    The lens was originally designed without an autofocus motor. This means it will not AF on the Nikon D40/D60 cameras. It uses the internal motor of cameras which is fast, but loud.

    The new version has its own focus motor which means it will work on the Nikon D40/D60 cameras. Tamron also added an AF/MF switch on the lens and fixed their focus accuracy issues. The focus is slower, but much quieter.

    If your lens has the AF/MF switch, it is the new version. I have the new lens and while it is great, I really wish it did better in poor lighting. It really has trouble focusing sometimes where Canon/Nikon lenses don't have any trouble at all.

    Hmm, how new are we talking? All the Sony lenses I've ever seen don't have an AF/MF switch on the lens since it's right on the body. Should I be concerned (try to get a newer one?) Will it be faster? I did notice it didn't match the one pictured online, but assumed that since mine was a sony alpha mount that it was just different.

    I'm not so sure TAMRON added anything to the other mounts. It probably is ONLY the "N" model numbers, such as Model # A18N AF 18-250mm f/3.5-6.3 XR Di-II LD Aspherical (IF) Nikon-Mount

    or

    Model # A16N AF 17-50mm f/2.8 XR Di-II LD Aspherical (IF) Nikon-Mount

    Don is probably right. I wouldn't be concerned though, and no the newer model is slower to focus. You might want to test focus accuracy though.
