It would be a great feature to have. Not just user modes, but all customisation would be neat. I made the mistake of leaving my K-1 without a battery overnight - all the settings and file-naming reverted/reset to factory. I was surprised that it was stored in volatile memory. It took a couple of hours to change everything back to where I like it, and still the file-numbering refuses to take a hint from existing SD Card; this means I have photos with same filename as earlier ones...
I suspect that there is a single config file holding all this info in the camera on-board memory, just the problem of:
- Reading data from the camera
- Decoding the data *
- Changing settings as required *
- Encoding the data *
- Writing data to the camera
(* to allow off-board configuration)
I can't imagine it would take much effort from Ricoh to add the code to save and load the config. Provided they documented the format, then I'm sure there is enough skilled programmers amongst the Pentaxian community to create a configuration tool. For serious/professional users with multiple bodies, this would be a godsend: @kenspo - can you ask the question?
