Canon adds 200-400mm support to EOS-1D Mark IV and EOS-1Ds Mark III

By dpreview staff on May 29, 2013 at 16:30 GMT

Canon has posted a firmware update for its EOS-1D Mark IV and EOS-1Ds Mark III full-frame DSLRs to allow them to work correctly with the new EF 200-400mm F4 L IS 1.4x lens. Firmware versions 1.1.3 (1D Mark IV) and 1.2.2 (1Ds Mark III) allow the cameras' central AF points to achieve focus with the lens when it is used with an extender, where the combined aperture is F8. Both updates are available for immediate download. 

Firmware version 1.1.3 for Canon EOS-1D Mark IV

Firmware Version 1.1.3 for the Canon EOS-1D Mark IV camera incorporates the following functional improvements and fix:

  • Enables the center AF point to autofocus when the camera is used with the EF 200-400mm f/4L IS USM Extender 1.4x lens and an Extender, whose combined maximum aperture is f/8.
  • Fixes a phenomenon in which abnormal images may result when continuous shooting mode is enabled and the image size is set to "RAW" or "RAW+JPEG".

Firmware version 1.2.2 for Canon EOS-1Ds Mark III

Firmware Version 1.2.2 for the Canon EOS-1Ds Mark III camera incorporates the following functional improvement:

  • Enables the center AF point to autofocus when the camera is used with the EF 200-400mm f/4L IS USM Extender 1.4X lens and an Extender, whose combined maximum aperture is f/8.
  • Firmware Version 1.2.2 is for cameras with firmware version 1.2.0 or earlier. If your camera’s firmware is already Version 1.2.2, it is not necessary to update the firmware.

why not give a general support for AF at F8 in center point as the previous 1D line cameras?

The 1Ds MkIII does have general f8 at center point already so there must be something strange about the way this lens reports to the camera if it needs a firmware mod.

"the new EF 200-400mm F4 L IS 1.4x lens ... when it is used with an extender ... the combined aperture is F8"

Shouldn't f/4 with a 1.4x extender give a combined aperture of f/5.6?

I think thats f4 plus in-built extender taking it to f5.6 plus external 1.4x taking it to f8.

it is a 200 - 400 f4 as is. And when you use it with the internal extender the aperture becomes f.5.6 and if you use an external extender it becomes f.8 max aperture.

For the MkIV file they're supporting 10.5 and higher, which isn't unexpected. The files seem to be the same thing from 10.5 to 10.8, makes me wonder why they don't just list them together etc but that's how their site is.

Anybody tried this out yet?
