    I suspect you either inherited that lens or got it cheap somewhere. It is not going to improve your photography. The best all-in-one TAMRON lens for almost any of the SONY DSLRs is the TAMRON AF 18-250mm f/3.5-.6.3 XR Di-II LD Aspherical (IF). In fact, this lens will be hard to beat, unless you start buying f/2.8 glass ... so that says a lot about its "bang for the buck." :thumbsup:

    Re: tamron 28-200 3.5/5.6 question

    All this equipment discussion is cool, but, what shutter speed / aperture are you using? Movement means you need a wide depth of field + a shutter speed of about 1/500 to "stop" the motion. I like to shoot kids at f8 or f11 which means plenty of available light or a good flash. Choosing between the two, I prefer having constant light cause as they get older they really move .

    Could be you could get a couple of photo flood bulbs to put in some heavy base adjustable lamps to solve a lot of the problem.

    I hope this helps.

    Cool Comparisons are important

    Okay, I feel this is important, so I'm going to give you a visual response curve for the aperture as you zoom this type of lens compared to that of the "kit" lens.

    Remember, the faster the lens jumps up, the worse or DARKER it becomes.

    Look at the ~50mm point ... the 18-70mm lens is already maxed out at f/5.6 ... while the 18-200(250)mm lens is only at f/4.5

    That's 2/3rds of an f-stop brighter that you can bank on.

    The Tamron 18-200 is a great lens according to everything I read, and, at $300 US reasonably priced. If I did not have the f4 beercan, I would probably order one.

    The beercan and either the 75-300 f4.5 Minolta or the 100-300 f4.5 Minolta lenses are almost always on a couple of the camera bodies.

    A word tot he wise ... do not buy the 18-200mm ... the 18-250mm is a quantum improvement over that lens. Spend the few extra bucks ... your photography is well worth it. Cheap never gets it done,

    Second the motion on the 18-250mm... If you are going to spend any money on a single lens solution, get this one in either the Tamron or Sony brand... Anything else is a compromise... Keep in mind this lens will most likely outlast any body you have too, glass is always a good investment...

    Re: tamron 28-200 3.5/5.6 question

    Bingo!

    Maybe that is what i should get for the sony 330. I been looking at minolta lens on ebay for days now. However, I read this is the best in world for a all in one lens with a 13x+ zoom. Would this jam pretty well for bike races you think?

    Thanks,
    BBR

    It is small and light. I think it would be as good as anything you could otherwise get.

    Personally ... it goes everywhere on my A100, my "Grab&Go" camera. :thumbsup:

    Is this the same lens? The XR is missing from the ad line?

    Yes ... XR is part of the design but has apparently been dropped from the description. I suppose it is not that exceptional, these days. It's still there.
