    I used the 28-300 at AirVenture, Oshkosh, WI ... and for the short stuff if was fine ... but telescoped to 300mm and infinity focus, it was woefully soft and OOF, in my opinion.

    So you can go to any telephoto length (28mm-300mm) you want, as long as you are under 27 feet and get a decent shot. Once you cross over 27 ft ... all bets are off at 135mm or higher.

    Here is an unaltered 80mm infinity shot (crop):

    EXIF: A700 w/ T 28-300 f/3.5-6.3 @ 80mm - f/4.5 - 1/1000 sec - ISO-400 - SPot focus - Spot Metering - S Mode

    It was pretty good, overall. I mean, what do you want from a utility lens?

    A little post processing to sharpen it a bit ... and here you go!

    Look, I did not create the optical laws of the Universe ... I simply learned to deal with them.
    Remember: It is usually the GLASS, not the camera (except for moving to Full Frame), that gives you the most improvement in your photography.
