sigma 150-500 on A700
Good Day to you All. Is anyone here useing a Sigma 150-500 on their A700??
I recieved mine last week. I'm finding it Very SloooooW to focus on an object and need to know if it is supposed to be faster. By time I focused on a bird in flight it's gone. My old 170-500 felt faster.
so far I have used No.1 & 2 OS on lens and switched it off and tried IS on Camera, All feel the same, Slow!
Once it looks on I'm getting Very good images. Very Frustrated as I was told it's much faster on the AF than the older 170-500.
Used Wide AF & Spot AF in camera, both same, slow.
Any info on this would be Appreciated.

I guess you've got the A700 set to fast focus - I know that some of the older Sigma lenses (not the 150-500) have tended to strip their gears when used in fast focus mode, so maybe you haven't changed your menu option. The old 170-500 had a few problems when used on the A700 in fast focus mode. Is it possible that Sigma, instead of beefing up the gears, just lowered the gearing? But maybe I'm being too cynical. I have to admit I've read so many problems about Sigma stuff on Sony/Minolta that I tend to stick to Minolta/Sony stuff. You don't get any nasty surprises.
