7D locks up repeatedly

Recommended Posts

<p>My 7D has locked up a number of times - no reason I can discern - twice this evening.</p>

<p>I documented this (and my other tests and reviews) on my photo teaching blog, but I have been told off for mentioning that blog here. Not sure I understand that (especially since i pay here) - but oh well, it is what it is. Anyway, it did lock up twice today. Anyone had the same?</p>

<p>Michael glad to see you got your 7d but too bad about the problems. Have you had a chance to test your 7D as the master flash to see if it will fire either a 580EXII or 430EXII in wireless manual mode in 1/3 stop increments? I am suspicioning that this fault with the wireles system in manual mode is in the slave side of the flash and not in the signal coming from the master. I was hoping that maybe, just maybe if it was a master signal problem that Canon would have fixed it in the 7D. </p>

<p>I've had a 7D for a week and so far smooth sailing: no problems whatsoever. Friggen rips. Okay, I'd like a RAW driver for Aperture. Can't get ECF or shiftable DEP mode to work. Oh, shit, I think Canon omitted those features...</p>

Sometimes the light’s all shining on me. Other times I can barely see.

<p>From my blog:<br>

"I came back to it ten minutes after reinserting the CF card and reformatting it. And I noticed that the LCD on the top was still on. A quick check: sure enough: no response to any button or switch – not even to the “off” switch. So again, take out the battery."<br>

Yes, with full battery. And I've tried various lenses and of course these lenses work fine on my other cameras (a 1D MkIII and a 1Ds MkIII).<br>

Hoping for a firmware fix soon...</p>

<p>Canon just released a firmware update for the 7D. If you're not already at 1.0.9 (dunno what versions they've been shipping, but I've heard not all 7Ds have shipped with the same version), you might want to upgrade, even if the description of the upgrade doesn't specifically refer to your problem. <a href="http://web.canon.jp/imaging/eosd/firm-e/eos7d/firmware.html" target="_blank">Here's the page with the new firmware</a> (along with a description of what's changed and how to do the upgrade).</p>

<p>Bought my 7D last Sat (10/31/09). Sitting here going through manual to know all the things about the camera. Picked it up to try the live mode and it was locked up. Not sure when it locked or if I had some button combo to put it in the lockup mode. Lockup was same as some of the other posts I've read....nothing accessible, no button response, on/off had no response, etc. Took out the battery, put it back in and all is well. My firmware version is 1.0.9....sigh. Looking for firmware version 1.0.9a or 1.0.10.</p>

<p>I've had my Canon 7D for about two weeks now, and used it on only its second shoot today. I had an identical problem to what Michael Willems describes: the camera was unresponsive with no buttons working. I checked the LCD, which was on, and that also did not respond to dial turns, button presses, etc. I turned the power switch to off but the LCD remained fully powered with all settings displayed. I removed the batteries, reinserted them, and the camera worked fine after that.</p>

<p>At the time I was using a 24-70mm L-series lens with the Canon battery grip attached. No flash attached or wireless flash triggering, and about 65 degrees out in nice weather.</p>

<p>My camera shipped with fw 1.1.0, so there's currently no update available.</p>

<p>I'll contact Canon shortly and see what they say, but thought I'd pop in and mention having the same problem.</p>

<p>Hi Michael,<br>

I've had the same problem with my new canon 7d. It locks up completely for no reason. It doesn't seem to matter what lenses I am using or how I'm using the camera. The off switch doesn't even work when this happens. All functions simply freeze.<br>

I've sent the camera to canon twice, and they still haven't fixed the problem. I'm pretty frustrated, but will be sending the camera back to them yet again. They say they've never heard of this problem before.<br>
