EOS Bodies - For Stills / Re: Canon 1DX - AFMA reset when I turn off the camera (workaround found)

« on: July 19, 2012, 12:32:54 PM »

So I called CPS this morning, thinking maybe I could have some luck with the issue. The lady I spoke with said they were aware of the issue from dealing with Neuro, and that they were not able to duplicate the issue on the three 1D X that they had tested it on. She wanted me to send the camera in so they could examine and document the issue. Since the problem is so subtle, I have a feeling that the problem wasn't conveyed correctly and they didn't test those cameras properly (the camera has to either go to sleep or be power cycled all the way, not just turning off then immediately back on, you have to wait a second since the camera doesn't actually immediately turn off). Otherwise perhaps we just got a bad batch at B&H that has a problem in some component. I'm guessing that Neuro, ThomasBX, Bryan at TDP, and I all got our cameras from the first batch at B&H, is that true? Are there 1D X owners here that really can't reproduce this problem?

Great video, but it is somewhat confusing because the adjustment values change when you remount the lens. You're entering +4 and -6 for lens 21. When you remount the lens, it recalls the lens and uses a previously entered set of values (+2 and +6). If you went one menu level deeper, it would show a different lens number.

You might want to clarify that the bug doesn't relate to the camera forgetting the adjustment values for a particular lens, but rather the camera failing to recognize the lens upon power-on or wake as a previously used lens, thus the camera registers a new lens with adjustment values and serial number of zero.

EDIT: I posted the following comment on the video better explaining what I mean.

"Great video John, but I wanted to clarify what is really happening here. Upon power-on or wake, the 1D X is failing to recognize the mounted lens as a previously used lens, thus numbering the lens 21 (in this example) and giving it AFMA values of zero and a serial number of zero. You then enter values of +4 and -6 for lens 21. When you unmount and remount the lens, the camera then recognizes the lens and recalls a previously entered set of AFMA values and serial number. The recalled values are now +2 and +6 because the camera is treating it as a different lens (since it correctly recognized it as a previously used lens). Going one level deeper would have shown a different lens number."

EOS Bodies - For Stills / Re: 1DX silent mode?

« on: July 18, 2012, 05:34:49 PM »

I too was hoping the 1D X shutter would be as silent as the 5DIII's shutter in silent mode. Would be helpful when photographing wildlife. Perhaps it's a design trade-off though as Neuro said - a shutter built for speed and durability just can't be as quite as that of the 5DIII. A silent-continuous mode would be nice, but since it wouldn't be all that silent... maybe it doesn't matter anyway...

Thanks again, Trowski!

Your welcome Neuroanatomist!

Long time lurker on this forum, but as you can see I haven't posted much. I may have to change that.

It seems that the camera firmware isn't doing the steps necessary to recognize the lens when the camera is initially powered on, but does when you switch lenses while the camera is on. Sounds like a simple firmware bug to me, something that can easily be fixed in an update. In the meantime, once you enter an adjustment, the camera uses the value for a lens of the same model, even though it initially thinks it's a new lens. I can see where this bug could have been overlooked. Most testers probably didn't micro adjust their lenses, and if they did, the value entered is still used when you take a photograph, even it doesn't show up correctly in the AFMA menu.

Does anyone know a good way of reporting this subtle problem to Canon so they can get this fixed in a firmware update?

EOS Bodies / Re: AF Point Color on the 5D Mark III & 1D X Update [CR2]

Perhaps an acceptable solution would be to just blink red when you first push the shutter or AF-On button so you can see which points are currently selected. This really wouldn't work if you had it displaying all the points, but honestly why would you want to have all those points displayed all the time? If there was enough ambient light, it wouldn't have to blink.

I used my 7D for a couple years and never noticed this problem, and it doesn't bother me much on the 5DIII... but I did notice it. Maybe it's because I usually only used the 7D outside?
