Sigma 777944

good lens with excellent image quality at an affordable price.

there is not much about this lens i did not like apart from the fact that i cannot use this lens on my film camera as it has no aperture ring, but this is not needed on my digital camera and will not affect many people.

Value for money

Quaity at 200mm

compact size, zoom range, price

noticable vignetting in bright conditions (lens returned to Sigma, but deemed within spec!)
