I am about to take a hack saw to the rail on my 4x5. The only lens I have on it is a 135mm, and don't plan on getting anything longer than 210ish (ever). The rail just basically adds weight, and gets in the way. Now I am going through the process of trying to figure out how long I need it to be. 90% of my shots are shot close to infinity, or a little less. I'm thinking 10" will be plenty long enough, even if I decide to do something close up? am I correct? Can I swing 8"?
