ldavidson Posted February 19, 2012 Share Posted February 19, 2012 <p><strong></strong>I have one day left on Kauia, Hawaii. This afternoon at the incredibly beautiful botanical gardens my auto focus and shutter stopped working. There is a number 8 in the view finder when I press the shutter buttom but the shutter does not move. When I switch to manual focus the shutter works, but I have difficulty focusing as I am a senior. My lens is a EF 24-70mm 1:2.8 L. <br> If anyone has advice I would be so grateful. I was looking forward to one more day of shooting.<br> Thanks!<br> Linda</p> Link to comment Share on other sites More sharing options...
robertbody Posted February 19, 2012 Share Posted February 19, 2012 <p>Did you try cleaning the contacts on the lens and body (where the lens attaches) with at least a finger/cloth, and with alcohol at best (usually finger/cloth can be enough).<br> I guess you're shooting handheld, so live-view and tripod are not an option.</p> Link to comment Share on other sites More sharing options...
tony_leinster Posted February 19, 2012 Share Posted February 19, 2012 <p>Have you tried removing the battery for a minute or two then replacing it, sometimes this will work for a software glitch as it effectively reboots the camera.</p> Link to comment Share on other sites More sharing options...
brian_wallace5 Posted February 19, 2012 Share Posted February 19, 2012 <p>Do you have another lens to try it with? If you try it with another lens and it works fine then it's the lens that's the problem. If the same thing occurs with a second lens chances are in the body. </p> Link to comment Share on other sites More sharing options...
randallfarhy Posted February 19, 2012 Share Posted February 19, 2012 <p>If the above suggestions don't work, you can try using live view with the magnification button to assist you in obtaining critical focus. Unfortunately, this is best used for work on tripods with somewhat stationary subjects.</p> Link to comment Share on other sites More sharing options...
roamingstudio Posted February 19, 2012 Share Posted February 19, 2012 <p>It sounds remarkable similar to an issue I had with my 7D and 24-105 whilst in New Zealand. There it was related to the compact flash - for some reason the in-camera formatting was screwing up. I changed to a CF card which had been formated in a friends canon 1D, or used my laptop to format it, and it worked. Of course I had also done the hard power off - remove lens, both batteries and wait 30 minutes.</p> Link to comment Share on other sites More sharing options...
ldavidson Posted February 19, 2012 Author Share Posted February 19, 2012 <p>Thank you all so much. I am going to try your suggestions, them I am off for my last day of vacation. It is a photographers paradise here. I'll let you know how it goes in a few days, when I am home. Aloha.</p> Link to comment Share on other sites More sharing options...
