 An Interesting Discussion, with Real People!
Good morning;
In looking at the "thread," it is obvious that there are some real people out here, with a sizable accumulation of knowledge, and some strong opinions. I admit that it has been interesting sitting in retrospect looking at the exchanges.
Soeren, thank you for the comment about using a laser pointer on the camera as an optical lever to show any mirror and shutter induced movement. So delightfully simple; so effective. One of those "so obvious" things that gives you that "slap-on-the-side-of-the-head" feeling along with the predictable comment; "Why didn't I think of that?" (Also, please accept my apology for the spelling of your name. I do not have the Scandinavian font set enabled on this keyboard.)
The comments about tripods I also found to be interesting. The lightest one in stock here is an old Husky Hi-Boy IV that weighs 7 pounds. There are also a couple of Bogen-Manfrotto and a venerable Davis-Sanford. All of them have the physical characteristic of "mass." I do agree with the comment about the light weight carbon fiber tripods not really being up to the task. As someone pointed out, you cannot get around the foundational laws of physics. By definition, something that is larger and has more mass will have a lower frequency natural resonance point and probably will be less suceptible to vibration problems. I tried to explain this concept to engineers specifying the poles for mounting television cameras used with vehicle detection systems for traffic signals, but had extremely limited success. As with some other comments, there is also the point that you can use the money you save, by not buying one of the carbon fiber tripods, for other things. A "win-win" scenario.
Guys, I think I have found a group that will be a very useful resource for someone who was given a 2 & 1/4 Square Medium Format camera a few years ago, and just recently has been able to drag out of storage and is now starting to get to know the camera and how to use it.
Enjoy;
