Nikon MC-25 2-Pin to 10-Pin Adapter Cord w/ MC-12A and F5 or F100.

Does an MC-12A (or MC-12) activate the meter in a Nikon F5 and F100

with a half press of the release button when connected to the camera

via the MC-25 adapter cord? Or does it just brainlessly fire at half

or full press without the nicety of meter activation and focus?

I use the MC-12a/MC-25 with my D1H, albeit with MF lenses, and it activates the meter normally with a 1/2 press, so I'd assume it would AF too if one were using an AF lens.

Yes I guess. MC-30 does everything you can do by pressing the shutter release button. So the mc-12 should do the same.

I have an MC-25 + MR-3, and it does activate the meter + focusing on a D1 or F5 when pressed half way. My MR-3 must be really sensitive, however, because the difference in how much to press to focus+meter and then to release the shutter is nearly nothing. I think that is due to the mechanical construction of the MR-3, and not due to the electrical characteristics of the MC-25 cable. If I press really careful, I can meter and release separately.

Thanks for the information! I�ll pick one up.

 

I�ve tweaked my MC-12A to have a nice "set trigger feel." I put a small self tapping screw in the underside of the fire button to set the backlash so there is only about 0.7mm to 1mm from half press to fire. The MC-30 is so sloppy I can�t tell when it will fire or when it will stop firing. I�m used to setting all motor drives to C and squeezing off single frame.

 

Yesterday I used my MC-30 and wasted three frames because I�m spoiled by the MC-12A.
