A quick dash to my local supermarket and 10 fresh AA batteries later, I reattached the motor drive and it now appears to work perfectly. Has anyone else ever noticed anything like this? Low voltage in the motor drive battery pack affecting the camera's ability to read the shutter speed dial? (I didn't even think that the camera drew power from the MD BP) This is the most bizarre manifestation of low-battery voltage I've ever come across. ======================================================================== Martin, it sounds as though the camera does indeed take its power from the MD when attached, although I wasn't aware of that. Maybe your R7 has some slight electrical resistance between the contacts in the shutter speed selector, due to oxidation and/or accumulated dirt. This may be sufficient to defeat the lower voltage of old batteries but not new ones. If this is the case, I would expect it to be a problem especially with alkaline cells, since their voltage falls off as they are used up. BTW, does the shutter selector work OK using the camera batteries, i.e. without the MD attached?
