Product Highlights
  • For Minolta Maxxum & Sony Cameras and HSM Lenses

The Sigma 2x EX DG APO Tele Converter (also known as a tele-extender) will multiply the focal length of the existing lens by 2x, and will cut back the amount of light by 2 f/stops. For example, using a 2x teleconverter with a 300 mm lens will effectively increase the focal length to 600mm. A lens set to f/2.8 will now be f/5.6.

Note: Sigma APO Tele Converter 1.4x and 2x are teleconverter lenses. Due to the high optical quality of this teleconverter, this item will only fit and work with a select list of lenses. Please click here for a compatibility chart of all compatible lenses.

The DG denotes an added coating that achieves the best color balance while cutting down on ghosting caused by reflections from the digital image sensor.

          Comments about Sigma 2x EX DG APO Teleconverter:

          I bought this 2X to use with my Sigma 50-500 zoom that I mount on my Sony A77. See my review for the 50-500zoom.The Sony A77 has a built-in 1.4 & 2.0 tele-extender. So if I attach the 50-500mm & 2X to the A77 and switch on the 2.0 internal extender it shows up as a 3000mm telephoto with the A77 cropping form factor. Very little resolution is lost, but no loss of resolution without the interna,2.0 teleextender.

            With this doubler mounted on my Sigma 70-200 f2.8 lens I was finally able to get clear shots of sandhill cranes that I missed before.Great piece of equipment!

              I use this with my Sigma 18-250 HSM, Sigma 70-200 HSM and my Sigma 50-500 non-HSM. Auto focus is lost on the 18-250 and the 50-500 but the IQ is not degrated.

                With the faster speed (more sensitive) digital cameras the 2X with 2 f-stops penalty is a great tool in well lighted gyms and for outdoor events. The action is right there, I use this with a 70-210 F2.8 Sigma lens and the pictures are sharp and clear. It shifts the center point a little given the extra length, but with a mono-pod its not a big deal. Little stiff getting on and off, but expect that to improve with use.

                  Comments about Sigma 2x EX DG APO Teleconverter:

                  Pros: doubling your focal length for one third the cost of a larger lens. More specifically, this teleconverter is perfectly matched to my Sigma 50-150 F2.8 EX DG HSM II (now discontinued).

                  Cons: cutting my original F2.8 widest aperture to a F5.6...it does make a little bit of a difference in certain low light situations.

                  this is a great addition to the sigma 70-200mm f2.8 HSM, the optics are very nice but the specific design only allows use with certain lenses. i carry it to extand the range when shooting wildlife which works well with the stabilized nature of all sony cameras. this turns the max apeture of f2.8 to f5.6 so low light focusing becomes a problem
