sattler123 Posted November 15, 2008 Share Posted November 15, 2008 Make sure the contacts between the lens and the body are clean. The shutter lag could be directly linked to the focusing problem - if the camera/lens takes forever to focus, the shutter won't fire until it has sucessfully locked on to something.

buffdr_rasouliyan Posted November 15, 2008 Share Posted November 15, 2008 To help T/S it better, switch to manual focus and focus on a subject in good light to see if you really have a shutter lag. Also, does it act the same way in different focus modes? v/r Raz Link to comment Share on other sites More sharing options...
rainer_t Posted November 15, 2008 Share Posted November 15, 2008 In order to verify Juergens point (shutter lag can be due to AF not locking), set the camera to manual focus, and try if you get the shutter lag. If you get the shutter lag, its an independant issue, if you don't get it, it's due to AF not being locked. Link to comment Share on other sites More sharing options...
dave_holland Posted November 15, 2008 Share Posted November 15, 2008 I see the above problem of slow autofocus and delayed shutter release when my 20D battery is starting to fade. Sub in an alternate battery before you jump to conclusions. Dave Link to comment Share on other sites More sharing options...
kasperhettinga Posted November 16, 2008 Share Posted November 16, 2008 Also shutter button problems can occur. If nothing is happening at all if you press the button (so also no light netering), that may be your problem. Link to comment Share on other sites More sharing options...
mark soares Posted November 17, 2008 Share Posted November 17, 2008 I agree with Kristen 100%. I believe your shutter button is failing and that is why the shutter is lagging and the af is lacking. It always happens when the camera has a certain amount of use in it and the result is a repair will be necessary. Usually this will require a shutter relase assembly replacement which is not the most expensive repair in the world. The way i would test this is to remove the lens altogether and set it to full manual (with flash off). Then try to fire the shutter. If there is no hesitation whatsoever then the problem was probably due to the fact that the lens (or camera) could not focus and therefore would not fire the shutter. If the camera hesitates from you just pressing the shutter button and you find yourself having to press really hard for it to fire even without a lens then you have a shutter release assembly problem and it will have to be replaced.
