Question about Canon EOS 40D Digital Camera

1 Answer

Firing "lag time" response

I have used my 40D for a year... Yesterday when I tried to take a photo, it took about half a second to fire, I have already formatted the memory card, I have cleared all Camera Setting..., I have tried in different autofocus modes, inclusive in manual, and still is "taking time" to fire.

Thanks a lot

    Thanks very much for your advice, I did it excatly as you mentioned it, I tested for about 60 shots, and it appeared working good, I will try on the field and I hope it is fixed.

    I did it, circling to the right and to the left, any particular indication?.

    This is weird...I purchased my 40D in September of 2007. Just today, I started getting the same lag as was described in this post. The focus acted normal, and responsive, but the shutter would take two or three seconds to take. I did the massage thing, and so far seems to have been the ticket. I appreciate the post and thanks for the tip!

    Same things. After 2.5 years the shutter release sometime won't respond.
    I have noticed that when I push it harder then it will fire.
    The massage thing didn't help.

Hi poseguerai, 
Try this:
I had the same issue and even if it sounds crazy giving a massage to the shutter button all around in circles helped and when you switch on the camera has no shutter lag again.
I hope it works as it did for me.

Remote Firing of Flash Units

The EOS 40D does not have a transmitter built in. The remote flash units must be set to "Slave" and the on-camera external flash unit (eg Speedlite 580EX) or transmitter (ST-E2) set to "Master". Note that the Speedlite 430EX doesn't have the function to act as Master and you need a minimum or the 580EX or a ST-E2 speedlite transmitter (or similar) as Master/s.
