Canon to Update Firmware for 5D MK III and 1D X AF with Speedlight Assist Lamp

Canon to Update Firmware for 5D MK III and 1D X AF with Speedlight Assist Lamp

New firmware coming
Canon has posted a article in their forum indicating that a firmware fix for the 5D Mark III and the 1dx is being tested to speed up autofocus when using the AF assist liight on a Canon Speedlight.  Many users have noted that focus is slow to be achieved compared with older models.  A quote from their post is given below.

“Canon has confirmed that, depending upon the shooting conditions, it may take slightly longer for the EOS 5D Mark III and EOS-1D X digital SLR cameras to acquire focus when using the Speedlite’s AF Assist Beam, compared with that of the EOS 5D Mark II and 1dx digital SLR cameras using the Speedlite’s AF Assist Beam. We are developing a firmware update to enhance the focusing feature for the EOS 5D Mark III and the EOS-1D X. The schedule for release of this firmware update will be announced shortly.”

A Small Sigma 180 f/2.8 OS Macro Issue

Issue with the new Sigma Macro
An issue with the Sigma 180mm f/2.8 OS Macro on the 5D Mark III and EOS-1D X has been discovered by LensRentals.com. If this has caused anyone to pull their hair out, the solution is pretty simple, just turn off illumination correction.

Below is an image taken by LensRentals.com showing the phenomenon.

The Findings

  1. The phenomenon shows up on Canon 5D Mk III and 1Dx cameras only. T4i and 7D bodies with firmware upgrade do NOT do this, nor do any other older cameras we could test.
  2. The Sigma 180 OS and Sigma 150 OS macro lenses both show the effect and it’s identical. No other Sigma lenses that we stock showed the effect, nor did any Tamron or Tokina lenses. Obviously I can’t test what we don’t carry.
  3. If you turn off Illumination Correction in the menu the effect goes away. To repeat, though, Illumination Correction in the 7D and T4i, on or off, doesn’t cause the effect.

The issue probably doesn’t show up on the APS_C cameras because of the image is about the same size as the circular anomaly in the center of the above image.

Another Full Frame Camera? [CR1]

Another Full Frame Camera? [CR1]

From POTN
Over a POTN there is a thread talking about a “1D X Successor”, basically a “slower 1DX”. Judging by the rumored price of $4000 AUD, I wouldn’t think it’s an “EOS-1″ body, perhaps a large megapixel camera above the 5D Mark III.

I believe we’ll only see one new full frame camera in 2012, unless something gets announced at the end of 2012 for availability in 2013.
