Laurent, for me the "softies" do make a difference - and I'm not alone in this. As soon as my friend got his M2 about two weeks ago, he asked me about a soft release - he saw that I have one, and said that the release on his M2 seemed too "recessed", i.e. too deep seated for a comfortable finger-press. So, if joe sends me any, one will surely go to his M2. I'll keep any surplus, since my Russian RFs could also benefit from such a device 🙂
BTW, Nikon also makes a bit more sophisticated device for their older SLRs - it's called "AR-1 soft release", if I'm not mistaken. It definitely makes using an FM or an older F camera easier to use.
