Regarding the recording level, I know that my Sharp 888 keeps the setting in memory when I stop the recording /and / or shut off the unit. Is it also the case with Sony's ? (I think not).
That could be very annoying when recording "on the field", if you need to go back somewhere in a menu to adjust level, every time you change the media or shut off the unit.
On the other hand, Sharp's do not have an automatic level feature, (read you have to adjust level all the time) and that can be useful also in some cases.
