Hi everybody, I know there is this thread about wether the AF-On button of the D600 works as expected or not, but I would like to get some more general information about when people here prefer this over the regular trigger button.
So far I found two use cases where I prefer the AF-On button over the trigger button and configured the custom menu accordingly to only AF using the AF-On:
- "Focus trap": prefocus on a certain distance using the AF-On and AF-S mode. Then press the shutter button and wait for the object to get back to the correct distance. I find this useful e.g. in Macro photography when there is no tripod available and you only can use a monopod or not even that. I found that in those cases I sometimes move forward and backwards more than I want. So I focus and then move slowly in or out and wait for the correct focus. Might also work for moving object (e.g. cars).
- Also in AF-S mode if you take images of static objects and you are not able to get a focus point on the part that you would like for focussing. For static objects and a tripod you could of course also use manual focus.
So what I would like to know is under what circumstances you prefer to focus using the AF-On over the shutter button and why.
