Summary: This and the sister teleconverter SAL-1.4TC will only work on two lenses in the Sony line. The trick is that it will fit the camera, but the lenses won't fit on the converter. The only two(2) lenses that will fit are the SAL70200G and SAL300F28G.
Excerpt: The Sony 2x converter works very well with my Minolta 200mm 2.8 HS APO G lens on the A900. Wide open at f/5.6 the pictures are full of detail already but with very low contrast. Stop down slightly to f/6.3 will regain the contrast.
Pros: Consistent Output, Easily Interchangeable, Lightweight, Strong Construction
Summary: The teleconverter works great. My photos are as sharp connected to the 70-200 G lens as without it. There is no degradation in quality in my experience. This adds a great option to my kit! I have no reservations recommending it.
Summary: Phenomenal results I cosidered buying the zoom 70-200 with f2.8 or the 70-400 with f4-f5.6 Eventualy I bought the 70-200 with f2.8 wich is a piece of GREAT optics with unparalleled results AND the 2X convertor Most of the time I need the 70-200 and when I'm taking wildlife pictures I'm using the 2X...
Summary: I spent a long time debating 70-200 with this TC or 70-400 without TC. I decided I'd rather have the really nice 200 and a not as nice 400mm zoom with the combo. I'm happy with the decision and when using a tripod this TC works great.
