Should you not use a remote release with Motor-M on an M7

I have seen some posts on RFF which recommend strongly against using a remote release if you have the Motor-M mounted on an M7. Apparently there is a considerable risk of breaking the shutter release switch if you do. I know the shutter release kicks quite strongly with the Motor-M, especially if you have the motor on the high speed wind setting #2. Someone else felt it would be OK to use an air release, as there would be sufficient elasticity in the air above the actuator piston to allow the release pin to be kicked back. 

 

Have others heard about this and is RFF correct or being over-cautious?

I commented upon the kick-back effect a few years ago and was poo-pooed. Thanks for bringing it up. I only trigger it by finger because of the same concern you mentioned.

 

An air release is encouraging! Thanks. I have one on the bench at this moment. Tinkering begins now.

Jac, 

 

I was playing around with the M7 and Motor-M when it arrived early this week with an old out of date film. I found it was difficult to take more than two or three on continuous because I was unsure how firmly to hold down the shutter release, against the kick back. I am going to have to put a soft release on anyway, as with missing the tip of my right index finger and it being rather immobile with arthritis, I find the shutter release of the M7 quite difficult. Let me know how you get on with the air release.

I have used a Motor-M with a cable release plenty of times in the past. It was pretty much the only time I used to engage the motor as it was useful for doing bracketed photos without having to manually wind the film and run the minor risk of moving the camera on the tripod. Admittedly, I didn't use the fastest motor drive setting but I never felt that I was going to cause any problems with the shutter release. Possibly if you maintain pressure on the remote release button as the camera winds you can cause damage but it seems natural to ease off after triggering the shutter to allow the "kick" to do it's thing unimpeded.

Ian, 

 

I am guessing it is only on Motor Setting 2 that the problem occurs. As you say, I cannot see any reason to use setting 2 on a tripod but setting 1, yes. Especially as at the moment I do not have a regular bottom plate. If I want machine gun pictures, digital is the obvious route to go.
