this is only compatible with select Sigma APO Lenses. Most other lenses won’t even fit on it.

Look very closely at the product specs before purchasing. They give you a very specific list of lenses it will fit.

The item arrived in the original box with all original paperwork, but with a Sigma worldwide warranty, not a USA warranty. If there were something wrong with it, I would have to send it to somewhere other than Sigma USA for repair or replacement which could be problematical. This has no bearing on the teleconverter, as it is a genuine product and works very well on my 70-200 f/2.8 EX DG lens. It has little or no effect on sharpness or color.
It’s possible that Amazon is unaware that their third-party fulfillment partner is shipping the lower-priced Grey item instead of the USA version since it is priced is the same as the USA version at B&H. It may also be that Sigma only has a Worldwide warranty unlike Sony, Canon, Nikon, etc.
Either way, be aware.

I did a lot of research on this item before I bought it. Nowhere did I read a bad review or rating and most buyers raved about how their pics remained sharp as a tack with the Sigma 120-300 mm f2.8 lens, but this is not what I experienced. All my pics are now slightly out-of-focus when I use this lens so I no longer use it and mark it off as a bad purchase.

Mating perfectly with the excellent Sigma 50-500mm lens, this teleconverter increases focal length. The downside is that it decreases aperture by 1+ stop, and you lose the autofocus capabilities of the lens.
