5D Mark III & 1D X Black Focus Point in AI Servo Information

5D Mark III & 1D X Black Focus Point in AI Servo Information

Some technical stuff for you
I wrote about this functionality a few weeks ago, and it appears no solution is in sight. I have been given a bit of information as to why it may be difficult to address.

Background
For some of us shooting the 5D Mark III, there is an issue that is driving some, not all, photographers bonkers. That is, when shooting in AI Servo mode, the focus point we have selected does not illuminate red, like it does on the EOS-1’s like the 1D Mark IV. The 7D has always had the black focus points in AI Servo and we never really heard many complaints about it. However, since the 5D3 came about, there have been countless complaints about shooting in AI servo mode without the illuminating focus points.

I finally spent a serious amount of time with the 5D Mark III, and I am on the side of it being extremely annoying that I can’t see my AF point in AI servo mode in various situations. Lowlight, black shirts, birds in flight and that sort of thing. With the 61 AF points, I do move the focus point off of center during AI Servo usage.

As mentioned, there have been lots of forum threads on the topic and I have finally heard from a few people what the issue is.

Below is some technical information about why (correct me if we’re wrong).
The transmissive LCD is the issue with both the 5D Mark III and the 1D X. Despite greatly improved AF, the exposure is affected by the red light of the AF point. This is why they do not light up in AI servo just prior to the exposure reading being made.

In order to solve the problem, Canon will have to figure a way to turn them on (red), yet adjust for the exposure differential. That isn’t as easy as it sounds, as each focus point will affect exposure slightly differently not to mention it’s also dependant on which exposure mode is active.

Can it happen?
It’s possible, because I’m told Canon is working on a solution. They do know a segment of photographer is having trouble with the black AF points. I am told the 1D X will launch with the same functionality as the 5D Mark III.

For some photographers, this is not an issue, or even a minor annoyance.

Canon EOS 5D Mark III AI Servo AF Point Annoyance Firmware Fix Coming

Canon EOS 5D Mark III AI Servo AF Point Annoyance Firmware Fix Coming

AI servo
A lot of people, myself included are quite annoyed at the black AF points when using AI servo mode on the 5D Mark III. It’s nearly impossible to see in some situations, especially in low light. I think most people would like the ability to turn on the red AF point you see when you lock focus in one shot mode. I’m not sure if this was by design, or if it’s actually something that was overlooked in testing.

You can see the discussions at [FM] and [POTN]

I will say that the AF works terrific in AI servo mode, it’s just tough to see the AF point at times.

Firmware fix?
I am told by a couple of people that the above issue is known by Canon and they will fix it with a firmware update in the future. The fix may take some time though.

Here’s hoping they also add the ability to change the image review zoom button mapping back to the top right.

You can let Canon know you’d like it fixed here.

Planet5D with Chuck Westfall
Chuck Westfall actually talked to Mitch at Planet5D about the two issues above. If I read anything into it, it seems the red AF point illumination is a priority and remapping the zoom button less so.

The issues come up at about the 8:00 minute mark, but the rest of the interview is worth watching too.
