Description

The EF 2x II doubles the focal length of any lens it's mounted to, and reduces its effective aperture by two stops. With the EF 2x II, AF is possible with any EOS body if the lens has an f/2.8 or faster maximum aperture, and compatible Image Stabilization lenses maintain the IS feature when used with any current EOS camera.

Carolyn: This is a great companion to any telephoto lense (that is compatible of course). I love to use this anywhere that I am looking to take photos of animals. Safaris, bird watching, dolphin watching, the zoo (I am serious). This is a great way to get a close up shot of your favorite furry creatures. I was so happy to have this on a safari. I have a 70-200mm and almost thought that would be good enough. If I had not had the extender, I probably would not know the difference, but there is no going back now. Especially at zoo like atrations (think glass walls and fences), the closer you get to that wall, the less you see the fencing and detail and the more you see the animal. It does reduce your aperture by two stops, so my 70-200mm 2.8 was effectively a 5.6. But, I did not run into any issues with this.
