I purchased this extender in the used dept. I read the rating and description before my purchase. When it arrived it was exactly as described and works great

The 1.4 extender connects perfectly to the camera body and the lens and all functions work perfectly. This effectively turns a 135mm lens into an almost 200mm lens with a loss of only 1 stop of light. The Canon 135L f/2 becomes an approx 200mm f/2.8 with beautiful results - and the combo is a LOT more circumspect than the white Canon zooms and teles.

Use this for sports photography when I just need a longer lens. It does what I need but is nothing special. Turns a sharp fast lens into a slower not as sharp lens, but if you need the extra focal length and can't justify the crazy price for multiple super tele lens this is a good option for the price.

I consider myself to be a enthusiast photographer that does sports projects for a fee. I traded my 2x extender to a friend in favor of the 1.4x. I found the chromatic abboration and the reduction in sharpness from the 2x to be too much when using my 70-200 f2.8 II & Canon 7D. I found that zooming in to 100% without the 2x to be as good (if not better) than native zoom with the 2x. With the 1.4x extender, I don't notice any loss in clarity but get the bonus of the extra 1.4x zoom. Gaining the extra stop of light helps too! Adorama was great. There service was spot on. And I would rate the lens better than their grade when I purchased the lens. Very Happy!

I bought this TC to use with my 70-200 f4 L while shooting high school field sports. In good lighting, it performs beautifully. I do notice a very slight a amount of chromatic aberration, but that can be fixed in post if it bothers you. The AF works just as it does without the TC and even tracks moving subjects fine. If you don't have the money for a longer telephoto or super telephoto lens, this will certainly hold you over until you do.

This product is useful when needed to extend the telephoto effect of lenses. It is most effective on f2.8 and f4.0 lenses.

Small and very light to carry around

Nice accessory

This product is useful when needed to extend the telephoto effect of lenses. It is most effective on f2.8 and f4.0 lenses.
This tele extender can be used with fixed focal length lenses 135mm and longer (except the 135mm f/2.8 Softfocus lens), and the EF 70-200 f/2.8L, 70-200 f/2.8L IS, 70-200 f/4.0L, and 100-400 f/4.5-5.6L IS zoom lenses.
Superb optically, it preserves the image quality of the lens it's mounted to and multiplies its focal length 1.4x.
Effective aperture is reduced by one f-stop; autofocus is possible on any EOS camera when combined with a lens having an f/4 or faster maximum aperture.
The new version II maintains the outstanding optics of the previous version, and adds enhanced weather- resistant construction, and improved anti-reflective surfaces in the barrel.
(When used with EF Extender EF 1.4x II, the EF100-400mm f/4.5-5.6L IS USM lens is compatible for auto exposure with all EOS cameras.
However, you lose autofocus with all EOS cameras except those with a 45-point AF system, such as EOS-3, EOS-1v, EOS-1D, EOS-1Ds and EOS-1D Mark II. Only the center focusing point is functional when this lens/extender combination is used with the 45-point AF cameras.
Also, when the EF100-400L is used with the EF 1.4x II, the Image Stabilizer function does not work with older EOS 35mm cameras such as the EOS 650, 620, 630/600, RT, 700, 750, 850, EOS-1, A2/A2E, 10s, Elan, Rebel/Rebel S, and Rebel II/Rebel SII.)
