It's Here!
I would normally expect the shorter zoom range to indicate better performance, but I haven't used either so I really don't know. I do know that if you're buying a new Sigma you need to buy it in a shop where you can put it on your camera and test it, as apparently their quality control can be a bit variable (but get a good one and it'll be fine).

OS on the lens can actually make sense with something like the Bigma as you can see when it is working, which you can't with in camera IS.
The Bigma has the reputation for a very good IQ - better in fact according to many than the 150-500. Obviously it has it's limitations given the size of zoom involved, and the slow long end, but it is an excellent lens, and one of my favourites.

I have heard one or two people say that this actually makes them feel "sea-sick", which is quite interesting. Nothings suits everyone I guess.
The "problem" there was that the train's tilting mechanism was too good. It was cancelling out all of the sideways G force that you'd normally expect to feel, causing an imbalance between the eye and the inner ear (which causes all motion sickness - it's the brain having a panic attack about how one sense tells it that you're moving while another disagrees). After the system was adjusted so that not all of the sideways G was cancelled out the complaints ceased.
With OS on a lens the image you see in the viewfinder will be stabilised, which could have similar effects as what you're seeing won't match what your inner ear is reporting.

I would imagine that it would make manual focussing difficult?

Sigma used to have a reputation for variable quality, mainly due to the reverse engineering I think. Nowadays though they have a good reputation and generally make excellent lenses.
This was primarily on Canon mount, because apparently Canon's AF routines are more difficult to reverse engineer or something along those lines. In fact Sigma lenses which are fine on other mounts* still occasionally have FF problems on Canon.
*i.e. it isn't a fault with the line like with the 50 f1.4

I am now on Flickr which is nice !
However, I found the in-lens OS made precise framing difficult, as the view would suddenly lurch about, rather than just wobbling as I'm used to with the in-body stabilisation. I suppose the lens steadies the image as much as it can, but when the movement proves to great, it has to re-align itself.
Seemed like a nice lens, but far too heavy for me. Been there, done that.

Or from an online retailer which pays for return postage on faulty items.
