I have the C740, which I believe works very similarly if not identically. Unless you have the camera in full time auto focus, I don't believe it actually focuses on the subject until you've pressed the shutter button half way. Until then, the subject may look in focus in the viewfinder, but is not. When you fully depress the shutter in one motion (rather than pressing half way first), the camera will attempt to focus before it takes the shot. If you are not careful about camera movement, you may inadvertently be focusing on something other than what you intended. My camera (and it seems all digicams) has trouble focusing in low light, so you definitely want to use the half press in such situations. Even then, I don't always get the focus correct. Thank the digital Gods for instant feedback! Personally, I almost always use the half press method.
To get the 740 in manual focus, you hold the "OK" button down until you see the viewfinder display a focusing scale. It takes a second or so. You should also see "MF" and "AF" designations in the lower left corner of the viewfinder when the scale displays. Use the left and right arrows to select the focus mode you want (i.e. MF or AF), then use the up and down arrows to adjust the focus distance. You'll notice that the area you are focusing on is enlarged when you use the up and down arrows.
