| p.1 #1 · 1DX/5D3 odd intermittent playback glitch explained |
I have custom functions set on both 5D3 and 1DX so that the set button jumps to magnified view of the focused point (and the main dial [top] scrolls the amount of magnification up or down). At times - and I haven't discovered what's different between when this happens and when not - when the image is magnified, the thumb wheel does not change images. I have to return to ordinary review mode with the playback button before I can move to another image. At other times, the thumb wheel scrolls freely between images, each magnified at the corresponding area.
Am I missing something, or have I come upon some kind of firmware glitch? It does seem odd that I get the same behavior with both cameras. Of course, now that I'm exploring and trying to reproduce the behavior, neither camera is doing it. If any of you have noticed this, can you connect it with any particular setting or operating condition?
Edit: Binh Ly explains it in the fourth post. It's when an image has just been captured and the set/magnify button is pressed before any other that the thumb wheel doesn't work. Of course, that's often exactly the time that I would like to be able to quickly compare the latest shot to the one preceding...
Further edit: As Ron Scheffler explains on the second page of this thread, these two bodies are the first (as far as he or I know) that allow a single press to display a magnified image. In other words, without first pressing playback, one can hit the magnify button (or the set button, which can be programmed to act as magnify) and jump immediately to a magnified image (which I've chosen to be life-sized of the selected focus point). In order for the camera to be ready for an aperture change via thumb wheel, it remains, in a sense, in shooting mode even though a magnified image playback is on. Ron's "solution", which I've adopted, is to disable image review. This just means the LCD doesn't show a just-shot image for 2 seconds or more. The display button still brings it up immediately, and the set button can show a magnified section immediately, without a press of display, plus it allows immediate scrolling to other images at the same magnified area.
So, in summary, we're convinced this is normal operation, by design, and in my opinion probably a good decision by Canon.
