Sigma 150-500mm in action

[Cowseye]

It only hunts a lot if the subject has very little contrast with it's background. In other cases it's silent and fast. Thanks to HSM.
The OS works great too. I can tahan the weight a bit as I tried to hunt down sunbirds with it. OS helps me get some shots too.

sorry guyz.. I need to OT a bit, anyone make any comparison between this lens and new APO 120-400mm F4.5-5.6 OS DG HSM ?

It is a very sharp lens, I hv it for 3 months for my Nikon D7000 but upgraded again to a higer version.
You can see some birds taken with this 120-400 and compare lol.
Look at those Wax bill ...sharp and details.

Am thinking of selling my 120-400mm DG HSM, less than 4 months old.So, just a feeler....anyone interested to take over...pls pm me. Thanks
