Canon has updated two of its older and now discontinued cameras, the EOS 1D Mark IV and EOS 1Ds Mark III, in order to support the recently-introduced EF 200-400mm f/4L USM Extender 1.4x lens.

The announcement of the Canon 1D X has been sad news for two professional cameras: EOS 1D Mark IV and EOS 1Ds Mark III. The EOS 1D X has replaced both of these shooters, when the camera was unveiled in the middle of 2012.

A pair of free firmware updates have been released for download by Canon. They are available for the EOS 1D Mark IV and 1Ds Mark III professional DSLR cameras and they bring support for the EF 200-400mm f/4L USM Extender 1.4x lens.

Canon has not forgotten all about the duo and it has released a pair of firmware updates to prove it. Although the 1D Mark IV and 1Ds Mark III have been discontinued, photographers who have spent a lot of money on them will continue to receive support, especially when the Japanese manufacturer releases higher-end lenses.

As a result, the Canon 1D Mark IV firmware update 1.1.3 and the Canon 1Ds Mark III firmware update 1.2.2 have been released for download. The upgrades can be downloaded for free and they are accessible worldwide.

The changelogs of the two firmware updates are almost identical. The EOS 1Ds Mark III gains support for the Canon EF 200-400mm f/4L USM Extender 1.4x lens, just like the EOS 1D Mark IV.

The Japanese company says that the updates are necessary, in order to allow the “center AF point to autofocus” when using the aforementioned lens that features a maximum aperture of f/8.

While working on the EOS 1D Mark IV update, Canon has discovered that a bug has been troubling photographers for quite a while. The company has decided to fix the bug that caused the camera to capture anomalous photos in continuous shooting mode when taking images at RAW or RAW+JPEG qualities.

This lens has been in the works for a couple of years. The EF 200-400mm f/4L USM Extender 1.4x lens was actually announced sometime in 2011, but it has failed to make it to the market until recently.

Canon introduced this lens on May 14, 2013, releasing it for pre-order. The product is available for purchase at Amazon for a price of $11,799 with an estimated shipping date of June 30.
