    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.

    Concerning D specs. and contacts

    wow, a few "simple" questions and a whole new learning curve opens up. Thanks for the info. Don, will study it more as time permits, have to work on basic skills more at the moment LOL. Everytime I think I got a base understanding on something, I find new questions and more details to learn, is this a hobby or a hell?
    BTW. do any of you guys "print and clip" stuff from the forums here? I have a three ring binder and I print out posts of info. or tecniques that have gave me explainations or ideas, and i put them in the binder as a quick review, self help book. I have it divided into settings, apreture, lenses, skills/tips, and P.P.

    Ive never printed and clipped everything lol. I just read it once and if it's really good, I subscribe without notifications and it gets saved as a bookmark on the forum where I can refer back to as a good resource.

    Usually I'm either able to recall something, go back and easily find it, or struggle to remember

    I usually don't print but if there's something I find useful, I will jot it in my little notebook that I carry around.

    Don, thank you so much for all your wonderful tips and techniques and I really appreciate the time and effort that you have put into writing and sharing it with all of us. The tips have helped me a great deal and I shall look forward to doing some interesting shots in the future.. You are doing a great service to photography community and I hope that many others like myself can benefit from your skills and good deeds. So keep up the good work
