Sigma 80-400mm F4.5-5.6 EX OS APO

Sigma_80-400_OS
Review Date: Mar 23, 2005 Recommend? yes | Price paid: Not Indicated | Rating: 10 

 
Pros: Sharp images at both ends. Fast and accurate AF. OS works well. Colour balance is good. Tripod socket & collar works well.
Cons:
Heavy ! Slow to zoom.

I bought this for wildlife, motorcycle racing and shooting the moon.
So far, it has been excellent. It would autofocus on the moon with my 20D at night. I have taken sharp pictures of birds in flight. Not tried the bikes yet.

Pros: Sharp images at all focal lengths. Fast AF. Good colour balance.
Cons:
The lens cap is an awful design. Why not make it one piece ?

I used it heavily when in Rome at the Colusseum. It worked very well and produced well colour balanced and sharp images. I also used in St Peters church where I was taking pics of the ceilings.
