I have a Nikkormat which seems in overall fine operating condition, but the shutter release button feels different from other cameras I have used, and I am wondering if the following behavior is normal for the Nikkormat: if I depress the shutter release slowly, there are there two light clicks along the way before shutter releases. This occurs with a cable release or with simple manual release. If I push the button down to allow two clicks, then let up on the button, the clicks do not recur, and the shutter releases like most I am used to. To those with Nikkormats, how do your shutter releases compare? Thanks!
