Howdy folks, My trusty GR-1 has developed an annoying problem...it quite often loses the focus and exposure lock when i press the shutter release button all the way down (from the half way position). Its as if i took my finger off the button. Sometimes it will do this 3 or 4 times before it works properly. This is pretty annoying as it has caused me to miss out on some good shots. Have any of you GR-1 owners out there experienced the same thing? I don't imagine theres a quick fix for this, i'm just looking for more info on it. thanks for your time
