Default Help! GF1 closeup

I've been practicing with a #2 diopter on my 70-300mm lens and having trouble auto focusing on my subject. Can you please give advice? The camera wants to focus on the surrounding rather than the subject. Is manual focus the answer?

I should note that I'm on point focus, hand held.



#1 this is probably one of my better ones, focused on his face but bad composition...





#2 just fuzzy, could be camera movement...





#3 not focused on the center flower, but just beyond..otherwise I think it's a pretty good shot





#4 same problem

You need to stop down to F10-16, there are in focus areas. But allot of the issue is the increase DOF that the larger sensor and the conversion lens gives you. Also go to center point AF. So you control where the camera focus on.

Take a look at these taken with a 70-300 and the amount of dof

Yeah, thanks. Next I'm going to try A priority and force the higher f stop. I'm already on center point focus. Also, I should probably try not to zoom in too much but move in closer instead. Zooming also seems to tighten DOF.
