Great TC from Sigma.. Like other brands it does not work with ALL lenses, but I have used it successfully with Canon lenses as well as Sigma. Excellent resolution is maintained.

Using this with a Sigma 500 F4 and it is great. Optically I see zero degradation of image quality. Better than I expected in every way. Not sure how it will behave on a slower lens (i.e - 150-600 zoom) since autofocus will come into play with many camera bodies.
Fantastic great product

I bought this item as an add-on to my Sigma 150-600mm f5-6.3 Contemporary DG OS HSM Lens. Being a keen, but very amateur photographer, I wanted the additional range which this brings (840mm) for nature photography. I have to say I was not disappointed.
Lot's of controversy over auto focusing. (will it ? or won't it. It works perfect at F/8 , mounted on the sigma 150-600mm. I was not sure how well the TC would work with the new sigma 150-600, until I tested it myself. I locked the Nikon in to aperture priority F/8 and guess what! work perfect.
