Hi Nikoners, a few days ago I found a chaep MR-3 ((cable) release adapter) after a long search for my F3's MD-4 motordrive to have an vertical shutter release button. But instead of being able to mount it on the grip side (MF-4 port) of my MD-4, it's only possible to use it on the other side - under the hot-shoe of the camera in the MD-4's remote control port. By this way, taking pictures in vertical position trying to release with my right hand isn't very comfortable... Is there any possibility, to get the MR-3 mounted in(to) the port dedicated for the MF-4's 250-exposure film back, to be able to release the camera with my forefinger? Thanks for any help with this ---- Marco Silbernagel | Maintainer of (German): http://privat.schlund.de/theNAIL/ | o Diarahmen-Tips Liste [EMAIL PROTECTED] | o Gebrauchte Fotosachen FAQ
