    i dun think u need to press any button for macro in SLR... if a lens is macro, the focusing can go beyond the standard focusing range, up to 1:1 or perhaps more, norm, 1:1 1:2 1:4 but there is a switch, that prevents the lens from going beyond the standard focusing range.

    if u talk about prosumer/consumer camera with the button, it might be same as SLR, its just a switch that lets the focusing go beyond.

    Yah, it's the switch I am talking about. So, what does the switch do? Or its just there to prevent blur user from going into macro mode without knowing?

    Thanks.

    i think the switch limits the focusing distance for close up subjects

    Ok, so I think it's just a limit switch for the photographer to do a deliberate switch...thanks.

    the macro mode is there in entry level DSLR to allow for slightly closer subject to lens distance for shooting with non-macro lens. But it isnt that great. Extension tube, reverse 50mm beats this hands down.

    I think those are taking advantage of the crop factor, and is close up and not macro....just like the S3 IS with crop factor of 6 can do "Super Macro" at 0cm, it is actually not macro, but just close up....can I say this?
