Apologies in advance; this is going to sound a bit like a lecture but I am hoping it will help at least a few people. In a thread a few days ago, someone stated that image stabilization for camera rotation was important because their camera rotated "with the pressing of the shutter button." IMO this is not a stabilization problem. It is a technique problem. Long story short, about ten years ago I spent a lot of time and money trying to get good at bullseye pistol shooting. I never really succeeded but tens of thousands of practice and match shots did teach me how to pull a pistol trigger. I release my camera shutters the same way. Here is what the Army Marksmanship Unit manual (Encyclopedia of Bullseye Pistol) says: C. APPLICATION OF TRIGGER PRESSURE. 1. Positive Uninterrupted Trigger Pressure - Surprise shot method - is primarily the act of completing the firing of the shot once starting the application of trigger pressure. The shooter is committed to an unchanging rate of pressure, no speed up, no slowdown or stopping. The trigger pressure is of an uninterrupted nature because it is not applied initially unless conditions are settled and near perfect. If the perfect conditions deteriorate, the shooter should not fire, but bench the weapon, relax, re-plan, and start again. ... when the shooter has established stable minimum arc of movement and sight alignment, he must immediately begin to press on the trigger, smoothly but positively, and straight to the rear without stopping, until a shot is produced. This method of controlling the trigger action will give the shooter a surprise break of the shot before any muscular reflex can disturb sight alignment. The key words here are "pressure" and "surprise." I start a shot withe the shutter button half-pushed. When I mentally commit to a shot I simply start to apply pressure, never knowing exactly when the shutter will trip. Since my finger isn't moving, I am not transmitting motion into the camera body either. My finger never intentionally "bottoms" the shutter button. The whole process takes maybe 1 to 3 seconds, during which I also hold my breath. In fact, an interesting thing happens fairly often with my current GX7s: I will get two shots. The shutter button doesn't move when my pressure triggers the shutter and something in the camera design often causes a second shot to fire. Maybe the shutter shock is enough to do this. I don't know. Probably many people do this already, not ever having handled a target pistol, but there it is. A little technique suggestion that will hopefully help someone to have a more stable camera.
