<p>I have had my copy for about a month. Unfortunately we have had a lot of rain, so I haven't been able to play with it as much as I'd like. I'm using it with a monopod, it's too heavy for me to handhold (but I expected that).<br> In my gallery, the photos of the heron, and the sparrow are all taken with the Tamron 150-600mm. They aren't tagged because I can't find the Tamron 150-600mm in the equipment list.</p>

<p>I just got mine a week and a half ago. I don't have enough experience with different lenses to have much to really compare it against. (My total experience with lenses: the 18-105mm kit lens, a MF 50mm I use for macro, and an old 70-300mm).<br> First impressions using it on a D90:<br> - this lens is significantly heavier than my previous lenses, it's a little too heavy for me to handhold and I need a monopod. On the other hand, it's light enough that carrying it around in a backpack isn't too difficult.<br> -the autofocus uses up battery power faster than my other lenses, but a backup battery solves that problem and would only be needed if you were planning to be gone all day.<br> -given the right conditions it can be quite sharp, even if the subject is in motion. The heron pictures in my portfolio were all shot with the Tamron on a monopod, as was the sparrow. I haven't really tested it in truly dim lighting yet.<br> If you have any questions I will try to answer them.</p>
