Originally posted by pxpaulx Great list Falk - I think the Fx button should really be opened up, would love to be able to assign it to turn on/off catch in focus as well as all the points you already listed (though having 5 name-able user settings does alleviate some of the Fx button's limited assignable attributes already).
Ok, this is a wishlist.
But I really think parts of the firmware need to be overhauled. Pentax follows the "one hand operates the camera" principle which is great. So, they didn't use much of the press button and simultaneously turn a dial philosophy. Currently, they only do so for the ISO and EV buttons. Some more buttons start a mode where the dials work too (MENU, INFO, PLAY).
It's not possible for every button position (for anatomic reasons). But to press a button and simultanesously turn a dial is a very powerful interface. E.g., Nikon uses it with a button located where Pentax has its focus mode selector to control the AF system (needs a 2nd hand but can be done while looking into the VF).
An obvious oversight is that the dial cannot change the burst mode after pressing the burst button. BTW, video should simply be a burst mode, with the various formats (24/25/30p) as submodes. This would allow to select it from within LV and map any burst mode (not just bracketing) to the Fx button.
All in all, wishlists are ok. But they have no impact compared to an accurate study of an improved interface with all details being sorted out.
