There seems to be some negative feelings about some of the cameras that require settings be made via the menu selections. It's deemed bulky and inconvenient, preferring cameras that do the same thing with more "convenient" buttons. On the other hand, as you say, too many buttons, too easy to hit the wrong one, and all with different functions depending on whether you're using the OVF or live view, or depending on which mode you're in. To me, that is really confusing. I think sometimes it's better to select the functions you want/need within the menu and use a single button to access them. The Fn button on the A6000 provides that ability, which I found very useful. Too bad Nikon hasn't discovered that. Maybe someone there will have the light come on and offer up a firmware update that allows that.

Jerry I find these very useful settings. I use U1 for landscapes and fixed and slow moving subjects. Aperture priority base of F/8 and other landscape type settings. I use U2 for BIF set to Shutter priority with a base of 1/2000ss and other settings for fast moving subjects. Very easy to setup, set your camera to the setting you wish to save (I call them base settings), go to the Setup Menu - Save User Settings, save as U1 or U2. On my D7100 the only modes I use are U1, U2, and M. One example would be a sunset. I go to U1 - 'A' priority with the base of F/8. Change that to F/4, change other settings. Now I want to go back to my Base settings. Switch the mode off of U1 to another mode then back to U1. You will now be back to your U1 base settings. This is how I use U1 & U2 hope this helps. - Bruce
