gregg_shipman Posted February 11, 2011 Share Posted February 11, 2011 <p>...This is true of any lens I put on it.<br> I've used my 5Dmkii for the last year with no problems. Models, sports, etc. you name it. <br> <br />The other day, I'm grabbing my camera to take some pics of a blizzard and out of nowhere, with no previous problems, it has decided not to autofocus. At all. Ever.<br /><br />If I have my lens (any of my lenses) set to AF, the trigger button is dead. No focus. No pic. If I switch to manual, it'll take a pic but no red focus light or pleasant beep when I'm in focus.<br /><br />Have I somehow managed to turn something off or is it repair shop time? HELP and thank you in advance :)</p> Link to comment Share on other sites More sharing options...
acedigital Posted February 11, 2011 Share Posted February 11, 2011 <p>Have you pulled the batteries and/or reset the camera to Factory Settings? Is your internal battery getting weak?</p> Link to comment Share on other sites More sharing options...
Robin Smith Posted February 11, 2011 Share Posted February 11, 2011 <p>Take the battery out and reboot the camera?</p> Robin Smith Link to comment Share on other sites More sharing options...
William Kahn Posted February 11, 2011 Share Posted February 11, 2011 <p>Did this happen only when shooting in the blizzard, or with other subjects, too? What were the conditions during the blizzard - lots of snow falling, low light, etc.? If so, that could have interfered with the autofocus...</p> Link to comment Share on other sites More sharing options...
gregg_shipman Posted February 11, 2011 Author Share Posted February 11, 2011 <p>I pulled the main battery - the date/time battery is only a year old. Reset to factory. Still not working. :( Thanks for your reply.</p> <p>G</p> Link to comment Share on other sites More sharing options...
gregg_shipman Posted February 11, 2011 Author Share Posted February 11, 2011 <p>Originally happened shooting around noon in cold (say... 25 degree) temps, outside of the elements.<br> However, the problem is persisting regardless of the setting at this point.</p> Link to comment Share on other sites More sharing options...
sattler123 Posted February 11, 2011 Share Posted February 11, 2011 <p>Sounds like a trip to Canon Service is coming up. Why wait?</p> Link to comment Share on other sites More sharing options...
gregg_shipman Posted February 11, 2011 Author Share Posted February 11, 2011 <p>Yep. Sending it today. Just talked to Canon rep and he walked me through several diagnostics. At least I wasn't going crazy! Dang though... </p> Link to comment Share on other sites More sharing options...
arie_vandervelden1 Posted February 11, 2011 Share Posted February 11, 2011 <p>Maybe clean the contacts on the camera's lens mount.</p> Link to comment Share on other sites More sharing options...
philip_wilson Posted February 11, 2011 Share Posted February 11, 2011 <p>It sounds like you my have got water into the camera - perhaps changing lens in the snow. Did the problem occur during the blizzard or when you got home. If it occurred when you got home it may be condensation inside the camera. I know my 5DII is fine in -25C weather and I have often used it down to -30 to-35C (it gets cold in the Canadian Rockies). If the temp was 25F (-3C) it is not due to the cold as my 5DII has survived temperatures well below this for weeks at a time. In high wind and snow conditions it is difficult to keep snow out of the body when changing lens so this may be the cause, otherwise it is probably condensation when you came into the warm. If you suspect it is condensation then you need to remove the battery and dry it out over time in rice or a bag containing silica gel packets.</p> <p>Blizzards conditions are actually more difficult at temperatures close to freezing (e.g. 25F) than they are in real cold (e.g. -18F) as the snow and air is dry in extreme cold and does not melt. All of your results point to water damage - assuming the battery is good. As I say if you suspect water damage get the battery out and get it dry immediately.</p> Link to comment Share on other sites More sharing options...
b_christopher Posted February 11, 2011 Share Posted February 11, 2011 <p>Greg, Just out of curiosity, what diagnostics did the Canon rep have you perform?</p> Link to comment Share on other sites More sharing options...
steve_dunn2 Posted February 11, 2011 Share Posted February 11, 2011 <cite>I pulled the main battery - the date/time battery is only a year old.</cite> <p>Pull 'em both; otherwise, the camera doesn't fully reboot. Cleaning the contacts on the lens mount is also worth a shot. Given what else you've mentioned, I suspect neither one will fix it - but they're both quick and easy things to do so they're worth a shot.</p> Link to comment Share on other sites More sharing options...
Marcus Ian Posted February 11, 2011 Share Posted February 11, 2011 <p>I'm also curious what they end diagnosing the problem as... let us know!</p> Link to comment Share on other sites More sharing options...
gregg_shipman Posted February 12, 2011 Author Share Posted February 12, 2011 <p>Thanks Phillip. It wasn't that however. I never exposed the camera directly to any moisture. It was actually the after-effects of a blizzard and merely snowing at the time + I was in a covered area.<br> It's definitely a mechanical failure of some kind.</p> Link to comment Share on other sites More sharing options...
gregg_shipman Posted February 12, 2011 Author Share Posted February 12, 2011 <p>The diagnostics consisted of walking me through the AF settings, asking for feedback of what was happening (or in my case, not happening), checking/cleaning the brass connection points on the lens and body, verifying none of the body brass connectors was stuck in a retracted position, resetting the body to factory specs and verifying that there were no other settings which were keeping the AF from engaging.<br> In the end, he concluded it wasn't operator error or some easy to fix issue such as fouling of connectors.<br> I bought it exactly 14 months ago.

b_christopher Posted February 15, 2011 Share Posted February 15, 2011 <p><em>How long does a warranty last?</em><br> Canon warranty is 90 days for refurbished products, and 1 year for new products.<br> http://downloads.canon.com/warranty/canon-usa-limited-warranty.pdf</p> Link to comment Share on other sites More sharing options...
morten_lohmann Posted February 15, 2011 Share Posted February 15, 2011 <blockquote> <p> How long does a warranty last?</p> </blockquote> <p>That depends on your location. Around here it's 2 years no matter what.</p> Link to comment Share on other sites More sharing options...
gregg_shipman Posted February 15, 2011 Author Share Posted February 15, 2011 <p>Well I've owned it for 13.5 months, so I'm hoping the guy who says two years is right.</p> Link to comment Share on other sites More sharing options...
