intervalometer wont work w 5Dm3

[mark_allen6]

<p>Hi all,<br>

I recently bought a 5D mk3 and thought I'd try my hands at timelapse using an intervalometer. I first tried using my PW multimax in intervalometer mode w the PW-recommended cable (CM-N3-ACC), but camera would not fire (well, it did once in 30+ tries). I've gone back & forth w PW, who are able to get their m3 to work w the multimax, but mine will not work following their instructions. My m3 will only work if I keep the shuttler pressed half-way (eg manually pre-triggered) - I shouldn't have to do that! So I just bought a dedicated intervalometer (a Pixel TC-252) - same result. No triggered photos unless I keep the shutter pressed halfway myself. I can find no info on what camera settings in my m3 might be confounding the operations of these 2 intervalometers. My Canon remote switch RS-80N3 does work to fire the camera, however.<br>

Any ideas?</p>

<p>Just a quick thought... try turning off AF on the lens.</p>

<p>yes, I've done that-no go. Is anyone out there using either a multimax in intervlometer mode or a pixel device w a 5D mk3 successfully?</p>
