Is it just me or is the AE-AF Lock button an awkward thing to use? I'm assuming I'm doing it the right way by using my thumb, but it's kind of uncomfortable and I feel like a mini contortionist trying to take a photo sometimes. Would be nice if I could assign this to the FUNC button or 'OK' button instead. Anyone else? (I hope) PS I'm a Nikon shooter (D90) but it seems that the location of this button is universal for Nikon and Canon at least.
