Thanks for the responses guys!
The BIGMA is a bit of a beast of a lens. A touch onthe heavy side but my arm muscles are developing accordingly!. The zoom was a bit stiff initially and I've had to get used to the twist zoom action having somehow managed to develop a push-pull zoom action with its predecessor the Sigma 170-500. As mentioned in other posts, in good light it is very good but once the light starts to fail I may as well pack up and go home.... ahh the joys (and expense!) of IS
! The build quality of the lens is also very good and the tripod collar makes a great handle for lifting the whole lot. Be aware though that a new version has comeout (DG) which I think has got better coatings on the optics(?), though apparently it's more expensive as well...
Phil / Mick,
I used to have a monopod and for a few airshows I would try swinging the camera around with the tripod attached.... trouble is it was quite annoying for the folks whose hats I knocked off!
... ended up selling it and the cheap Velbon tripod on Ebay. In their place I've recently invested in a SLIK Pro 700DX tripod with the 4 way head... Lovely bit of kit and rock solid!
Anyway, back to the subject at hand... not many folks using tripods.... didn't think so.
