Take a look at the shots and the thread. Either the Sigma
is just plain terrible, or the Olympus is fantastic.

That's an interesting comparison, but of rather limited value. It does
clearly show that very cheap lenses are often not as good as dearer lenses.

The Olympus 50-200 f2.8-3.5 Lens is $999.95 from B&H
The Sigma 55-200 f4-5.6 DC lens is $159.00 from B&H

Shooting the Sigma wide open compared to shooting the Oly at over a stop
down shows the Oly to be sharper, wow - big surprise!

For the price of the Oly you could buy a Sigma 50-500 lens.
For less money you could buy a Sigma 70-200 f2.8 EX. I wonder how a
comparison shot at 200/5.6 would look between the Oly and this lens?

Odd. I run Panicware and it was preventing some images from showing.
But most linked images, 95% show up right from the get-go.

A lot of things aren't available on the 4/3rds platform.
