Sigma 736927

Good image quality through it's vast super-zoom super telephoto range. Nicely balanced when used on a mono-pod with my 40D. The damping effect of its mass means that reasonable shutter speeds can be used even at 500mm. For the price you get a lot of EX...

A bit of a beast to lug around.

Simple Easy to use and get use to.

Weight is the only drawback

It was what I had been looking for and I feel that it will fulfil my requirements.

As yet have'nt discovered any bad points.

very fast focus easy to use

needs monopod or tripod due to weight

High quality images throughout the zoom range. A3 size on a Canon 30D very sharp.

Has to be large and heavy to produce this quality output. Zoom rather stiff.
