I just got this very interesting lens, the Tamron SP AF 200-500mm f5-6.3 Di.
My thoughts on this lens is,
- Very light for such a long lens, weighs about the same as my 70-200 2.8 L.
- The build is pretty good. Never owned a tamron lens before so not sure if this is standard but it doesn't feel cheap. Feels high quality.
- The aperture is 5 to 5.6 until 450mm!
- The color of the shots I took seems to ber very nice.
- The AF speed in light seems to be fairly fast, in dark not so great (but Canon lenses do that also)
- Price, like $850 for a Power Zoom lens.
- It's fun!
For its money I think this is a lens to consider and is pretty fun.
So here are some sample images taken with this lens. The Tweety Bird was taken at around 300mm and the Crab Apples were taken at 500mm and both were hand held.
I would love to see images from others with this lens. Please post some if you have this lens.
NOTE (December 10 2011): The sample shots I included were edited from RAW on a PC with an UNCALIBRATED monitor. So the reason they seem a little washed out, is because they are. Its not the lenses fault entirely.
