I'm looking for a power drive for my 1000s. Some that I've seen come with a coupler, some don't. What is the purpose of the coupler? Is it necessary to have one to use the drive with my camera? Cheers.
Yes, the coupler is a little piece that connects the drive to where the crank would go on the camera. If you don't get one with the drive, you will need to find one elsewhere. I am not sure, but I suspect they might be a bit hard to find by themselves. Certainly get an idea about whether you can find it before you invest in a drive that comes without.
About $30 for a coupler that should come with a $75 drive. Seems like you are better off getting the drive with the coupler included if that is what a replacement will cost.
