Using Extenders with the EF 200mm f/2L IS USM lens.

 

Description

Using Extenders with the EF 200mm f/2L IS USM lens.

Solution

Extenders

With Extender EF1.4X II or EF2X II attached, the lens specifications will change as follows:
Item With EF1.4X II Extender With EF2X II Extender
Focal length (mm) 280 400
Aperture f/2.8 - 45 f/4 - 64
Angle of View Diagonal 8°50' 6°10'
Vertical 4°55' 3°30'
Horizontal 7°20' 5°10'
Maximum magnification (X) 0.18 0.24
 
  • First attach the Extender to the lens, then attach the lens to the camera. Detach it from the camera in the reverse order. If you attach the lens to the camera first, misoperation may occur.
  • Only one Extender can be attached to the lens and camera.
  • If you use an Extender on the lens mounted on a EOS A2/A2E/5, set the exposure compensation to -1/2 stop for the EF1.4X II or -1 stop for the EF2X II.
 
When an Extender is attached, the AF speed will become slower by design to retain proper AF control.
