Anyone knows whether EN-EL3 and EN-EL3a can be used with the D300? I know the manual says you can't because you won't get the battery info, but will there be any other adverse effects if you do use it?
My experience with D200 is that you can't even put the battery in. There is a mechanical notch and the notch is smaller on the 3a. The 3e has a bigger notch and so can fit in the D200/D80 as well as D70s/D50. Electrically, I masked off the centre terminal of the 3e and the D200 just refused to start.
