Canon Extender EF 2X III SKU: 4410B002

Rated 5 out of 5 by from Extender EF 2x III Just have Patience when using this lens Extender. Perfect for nature images. Not so involving sports images especially movement. Otherwise, a great lens addition. :-)

Rated 5 out of 5 by from Extender EF 2x III Extender EF 2x III Is exactly what I needed to extend the range of my EF 300mm f2.8 lens. Auto focus works as it should although at slower response. That delay has impacted by sports photography but not my nature photography. As always, Canon did a great job thought the order process and shipping. I am very satisfied.

Rated 4 out of 5 by from Happy with my purchase Sharp image. Minor complaint is that I didn't consider that I wouldn't be able to open up my 70-200 to 2.8 with the extender on. Other than this miscalculation on my part I'm pleased with this piece of equipment.

Rated 5 out of 5 by from 2x Extender Without this extender the EF70-200 would not be worth my time as it doesn't go out far enough. This has helped considerably.

Rated 5 out of 5 by from Outstanding addition Works great on my 500 f4 ii lens. Minor IQ loss, well worth it for the added reach.

Rated 5 out of 5 by from Easy way to increase your zoom capabilities I bought this extender to complement the 70-200mm telephoto. It adds a lot of capability at a reasonable cost and is worth the investment
