I was shooting the 8x10 for the first time in about two years yesterday. I should say I was trying to shoot. I got one shot off when I realized, even with my cable release the whole camera shook. I am using a 300mm schneider something which is one hell of a big piece of glass (It is in my bag and I am too lazy to go look) but I have never seen it flop like that. Clearly this shot is toast. I spent a lot of time trying to figure how to make it not flop. I was shooting in our boat repair shop so I finally ended up with an outdrive jack lifting up a stool with a boxed gear set on the stool bracing the rail. I used the gear set because I found I needed some heft to steady the box on the soft seat of the stool. That was one sturdy fully adjustable rail brace but completely impractical for field shooting. There is no way the last shot will be messed up due to camera shake. Is this a problem with the tripod head not being built for the camera. It has a weight rating that should not be a problem with the camera? It is a bogen 3029 on an after market heavy duty tripod. I was not shooting at infinity so the bellows was out a ways. Anyone have any thoughts on how to keep this sturdy. Like I said, I have never seen this before but then again I never used it closer than infinity.
