Tamron AF200-500mm f/5-6.3 Di LD IF Lens

Thanks to Tamron for lending me this lens for a day at the Cincinnati Zoo.
Since I knew I would be walking a lot, I took only my mono-pod with
me. I am very impressed with this lens. It can take very sharp photos.
Being new myself to the world of DSLR's, I had some problems at
first trying to figure out the shutter speed and exposure settings.
This you could not fault the lens. Seems, no two shots were in the
same light. I would go from very bright sunlight to dark almost a
forest type shadows. Got some great shots of a Bald-eagle, sitting
on the ground in shadows through a chain-link fence. Even shot
bees in a tree about 25 feet away hand-held, Took a picture of a
Rhino and feel I can count the hairs on its head.

Will give you very sharp photos.
Zoom range of 500mm
Build quality felt good.
Just love the design of Tamron's
lid caps.

Not a hand-held lens. Should at least use a mono-pod.
Wide open of 200mm could be a problem
