Having owned the 150-500 OS I swore I'd never buy a budget telephoto zoom again. And lets face it even if this Sigma costs 2K its still a budget telephoto zoom in terms of the focal lenght and features you are getting for your money. I will watch this one closely as I expect the image quality of this lens will be very acceptable. I'd like to see how it compares to the 120-300 S+2x both at 600mm and both at F8.
I currently use the Sigma 300+2x which is alright at F8. I would prefer Sigma to update that lens and I hope they do or else a 400 F4 OS would be very sweet.
Here is the tamron 150-600 vs the sigma 120-300. Tamron is sharper in the center but the sigma is better in the corners. http://www.the-digital-picture.com/Reviews/ISO-12233-Sample-Crops.aspx?Lens=929&Camera=453&Sample=0&FLI=5&API=2&LensComp=844&CameraComp=453&SampleComp=0&FLIComp=7&APIComp=4
