That was my other concern too. Does it feel similar to use than the D300's AF-ON though? I use it exclusively.
Can't get to a camera store at the present time to have a test.
It's in the same location as the D300 AE-L button, so it's significantly to the left of the AF-ON location, however the body for the D7100 isn't quite as large, so I do not find it uncomfortable to reach. On the D300, when holding it normally, the AF-ON button is right where my thumb lands, whereas the AE-L button requires me to reach. On the D7100, I do not have to reach for the button.
