[QUOTE="nickt, post: 457222, member: 4923"] This might help you understand the focus modes. [URL]http://alexdanev.com/forum/Books/nikon/D7000_AF_Explained.pdf[/URL] You wont really see more than one focus point selected, although you might see several points flash briefly in auto area mode. Check out that document. It is great info. It sounds like you might be thinking more focus points will let more of the scene be in focus? That is not the case. The various focus modes will acquire focus in different ways and they are all useful in different situations. No matter which mode, the camera will only focus at one precise distance. Forward and back from that distance is covered by your depth of field. Only a higher aperture will give more depth of field for a given focal length and distance. You can experiment with zoom and subject distance to get a greater depth of field for closer subjects. You may benefit from single point focus in a deeper group of people. Rather than focusing on the first row, use single point and focus on someone mid-crowd. Or use manual focus. That will help balance the depth of field front to rear. You will still need an appropriate aperture to cover front to rear focus, but focusing mid-crowd can help. More light or flash will help too. [/QUOTE]
