Canon 2x Teleconverter II

In Stock

Canon 2x Teleconverter II

This teleconverter provides 2x image magnification at the cost of 2 f-stops of aperture. Some loss of image occurs even when used with L quality telephoto prime lenses. While the 2x can be used with “L” quality telephoto zooms (70-200mm f/2.8 and longer), we don’t really recommend it for the 100-400mm Canon zoom or any 3rd party zoom. On non-1 series cameras, use of a 2x teleconverter will require manual focus on any lens with an aperture greater than f/2.8.

Roger’s take: Well, there is no free lunch. If you could double the focal length of a lens with no downside for $250, then why wouldn’t they just build these in? 2x teleconverters are useful if you’re shooting L-series telephoto primes on a tripod, especially with a 1D series body.

However, they are going to give up 2 f-stops of aperture, making an f/4 lens an f/8 (that will probably be sharper stopped down to f/11). On a non 1 series body, that’s not going to autofocus at all (or at least not at all accurately). On a zoom, they’re going to degrade image quality, although a few folks do shoot them on 70-200mm f/2.8 lenses with decent results.

If you haven’t used a telconverter before, please read about the limitations they have HERE

PLEASE NOTE: the Canon 2x will not fit on wide angle or standard zooms, wide angle primes or third-party lenses. For these you should use the Kenko 1.5x converter for Canon which will fit almost every lens.

REALLY PLEASE NOTE: If you rent a 2x teleconverter and are using it on any lens other than the Canon 200mm f/2.0 IS, 300mm f/2.8 IS, 400mm f/2.8 IS, 500mm f/4 IS, or 600mm f/4 IS, you are probably not going to be happy with the result, if it works at all. If you decide you want to use it with another lens, do so at your own risk. Please don’t expect us to refund the rental when it didn’t work with your 70-300 f/5.6 zoom.
