Add some versatility to your existing Canon EF-mount lens collection with this 2x DGII Teleconverter from Bower, which contains 7 elements to ensure sharp imagery. This teleconverter utilizes multi-coated optics that will double the effective focal length of your EF lens, for example it will convert an 85mm lens to 170mm. This doubling effect has a light loss of about 2 stops, meaning an f/1.4 lens will become an f/2.8 lens. Additionally, this teleconverter offers full communication between the lens and camera to enables autofocus and other electronically controlled functions, however it is not compatible with EF-S mount lenses.

    2x DGII Teleconverter with 7 Elements for Canon EF is rated 3.5 out of 5 by 6.
    Rated 3 out of 5 by from Works well at Outdoor shooting I recently owned this product, need to explore more.... I use Bower 2X Teleconverter with 50mm f/1.4 USM Autofocus Lens. I got a 100mm lens for cheap. Please note: 50mm lens becomes 100mm however 1.4F becomes 2.8 when 2X Teleconverter is fixed. I had noticed dark images shooting indoors with this 2X teleconverter - may produce better results if an external flash gun is used or for Outdoor shooting! I also experienced troubles / huge lag in Autofocus - using this teleconverter with EF 70-300mm 4-5.6 IS USM lens - indoor.

    Rated 3 out of 5 by from Chromatic aberration I use this teleconverter with a canon 75-300mm I like it! notice the aberration when at 300mm. I don't seem to notice the Chromatic aberration, when not in use with the 75-300mm lens. worst when taking pictures of the moon. Handy to have, just don't expect to be as good as the canon X2 teleconverter, but sure beats the price!

    Rated 1 out of 5 by from Bower Teleconverter Tried the converter on my Canon 60D with my 70-300 lens. Wanted to use it for sports shots of my son's baseball teams. Images were to soft and it wouldn't focus quick enough.

    Rated 5 out of 5 by from Great Accessory I shoot surfing and so many surf breaks are way out away from shore. It would be a waste to even shoot at all without this 2X Teleconverter. I'm pleased with the resulting images and cannot detect any breakdown in image quality. Good product.
