hi dps members does any body have an opinion on the sigma 50-500 lense . i am thinking of buying this lens ,i would be using it for sports / action / daylight shots.thanks

Sports and action? Not likely. The 50-500 is a f/4-6.3, so you'll need some high ISO, even outdoors, for the shutterspeeds you need.

thanks for the reply os .what f # should i be looking for in that length , i would be shooting at the 500 end most of the time ,in the aussie midday sun , quote from didital wharehouse site = (This lens is equipped with Sigma’s unique OS (Optical Stabilizer) function. This system enables hand held photography for many types of subjects such as motor sports, air planes, macro and wildlife.)

The Stabilizer helps for stationary subjects: it cant freeze motion.

The best you'll get at 500mm is likely to be f/4, which is already a full stop and a third better than the Bigma.
