sigma 120-400 ??
 

I am thinking of buying a Sigma 120 - 400 OS lens.Does any one know how good they are as the price seems reasonable.Where is the cheapest place to buy

i have been using the sigma 135-400 which is the previous model ,i had it re-chipped to run on modern canon cameras and quite honestly the results where superb .good choice of lens for general purpose work and great for wildlife pics ,mines for sale (cheap as well) now due to switching from canon to nikon .whichever way you go new or s/h there a good lens

Thanks Jeff,I use Nikon D80

just an update for you ,i swopped equipment around with my lad as he wanted to go back to canon,so i now have the nikon D90 + 3 lenses the main one being the sigma 150-500 dg os (bigmos) there is a definet improvement with image stabilisation so if ,your going for the 120-400 i would expect great pics coupled with the d80
