What is extender RF 2x?

Extends a super telephoto lens’ focal length by 2x, so that an 800mm focal length, for example, becomes 1 600mm. The extra reach makes it possible to get larger close-ups with the original camera resolution.

Are Canon extenders worth it?

The Canon Extender 2x II works great, but it only can do so much. It really does give a much longer focal length, but with two stops less speed, while remaining pretty sharp and with very good AF performance. AF is slower, especially if it has to rack a long way in or out.

What is the difference between Canon Extender II and III?

Results with the Extender 2x III are overall slightly sharper than the Extender 2x II with a difference being most noticeable in the mid-frame and corner areas. The 2x II added pincushion distortion to the lens it was used with whereas the 2x version III adds slight barrel distortion.

Is the Canon EF 2x III extender the same as the 1.4x?

Is the Extender 2x III worth the money?

The 2x is good on the 300/2.8L IS Mark II, but even then the AF suffers so the hit rate is lower (and very frustrating sometimes!). It’s usable on the 500/4L IS II especially on a tripod. I have all of these items (except the 5D3) so no axe to grind, just what I’ve found using mine.

What kind of lens does a 2x extender make?

Combining the focal length multiplier and the maximum aperture reduction provides your resulting lens equivalent. For example, a 2x extender (also commonly referred to as a teleconverter) makes a Canon EF 70-200mm f/2.8L IS II USM Lens into a 140-400mm f/5.6 IS lens (yes, IS still functions normally on all compatible IS lenses).

Can a Canon EF 70-200mm lens be mounted over a 2x extender?

For example, a 2x extender (also commonly referred to as a teleconverter) makes a Canon EF 70-200mm f/2.8L IS II USM Lens into a 140-400mm f/5.6 IS lens (yes, IS still functions normally on all compatible IS lenses). A Canon EF 70-200mm f/4.0L Lens mounted over a 2x becomes a 140-400mm f/8 lens.
