hi guys

today I've been to see some owls and thought I'd try manual modes as well as some tips I've read on here. One tip was to get as low as you can so that you can be on the same level as the bird. Below is a pic I took, posted in its 'raw' state ie no PP at all. After I took this I tried to get lower, so same settings, just lower down. But, the shutter would not react at all. It seemed to be focused ok, but the button would not work. I tried some things - going to manual focus, changing some settings, but nothing worked. Does anyone have any ideas why? This often happens when I try to do close up stuff :-(

My guess is Summer that the lens has reached it`s minimum focusing distance and cannot lock on, it might appear through the viewfinder to be focused but it has not. Only a guess though.
 
:plusone: I have done this many times, I do not know about th e400D but on my 50D there is a solid dpt that flashes in the right of the view finder when you are closer than min focus

I guess more trial and error then, mind you everyone around me thought it was funny seeing me on the ground ha ha
 
Did you hear the AF confirmation beep? As said above it's likely you were beyond minimum focusing distance for the lens, in which case the camera will just refuse to take the photo unless you switch to MF (also pointless as you still can't focus any closer).

As above, it does sound like your camera / lens is too close to the subject to obtain focus.

Also depending on what AF setting you are using, the camera will not fire if a focus lock hasn't been acheived.

In 'one shot', it has to acheive a focus, in 'AF Servo', it doesn't - hence if you do sports and fire off a series of shots in AF Servo, some can be completely out of focus.

If you have a look at the lens / manual or a quick google on the manufactor web it should tell you the minimum focus distance...
