Bower SX7EOS 2x Telextender with 7 Lens Elements
The Bower SX7EOS 2x Telextender (also known as a tele-extender) will multiply the focal length of your existing lens by 2x, and will cut back the amount of light by 2 f/stops while maintaining full autofocus coupling.
For example, using a 2x teleconverter with a 300mm lens will effectively increase the focal length to 600mm. A lens set to f/2.8 will now be f/5.6. With a 7 elements optical design this telextender yields superior field flatness and edge sharpness compared to converters with fewer elements.
Teleconverters are not recommended for lenses wider than 50mm, e.g. 28-105mm. However, full AF operation is only possible with lenses with open aperture of f/2.8 or brighter. Please be aware that AF will work properly only if there is enough light and contrast on the subject to activate the camera's AF sensors. Manual focusing is recommended when using lenses with smaller open f-stop value than those given above.
Note! Not compatible with EF-S lenses.
- Compact and lightweight
- Precision engineered
- Doubles the focal length of your lens while full auto coupling is maintained
- 10-Year warranty against defects in manufacturing
- Made in Japan

I was told teleconverter would not work with this lens (18 -250 sigma dchsm)[...] they are right to a degree,it will go on it ,will in proper light auto focus but best to manual forcus and you do not get the full 2x but it does work some what.I think for the money it was worth it and you may get a different lens in the future
