The big advantage is obviously the long end.
It is reasonably stopped at 500mm and wide open and I'm happy. I don't expect the same performance from this lens as my 85mm/1.4 GD. Neither should you.
I got sharp images at 1/80s, thanks to SSS at 500mm f/6.3.
At f/8 and f/11 it is remarkably sharp but obviously not as good as the 70-400G.
Focus hunts a bit in low light but that's common to lot of other cheap zooms.
It is a slow lens, though, and I think it hits f/6.3 by 250mm or so. This is a good daylight/bright light lens but not suitable for hand held indoor low light shots. But then one would need to be quite inexperienced to expect that kind of performance from this lens.
The immediately obvious uses of this lens is for birding, airshows, sports, moonshots etc. I haven't used it on my A700 (yet) but I'm expecting quicker focus locking than my A100. Still, it could be a little slow for airshows, sports etc unless you pre-focus and shoot.
I don't have a problem hand holding at 500mm even at 1/80s.
On the whole, I am very satisfied. Check out some of the sample images I have posted.
