Q: Has anyone made a chart of which screw-hole to use (for the front standard) for which focal length lens?
A: I don't know of a chart, but since there are multiple ways of setting up the camera there won't be one definitive chart. I try to push the back forward for short lenses. Each hole is 25mm from the next, so it's pretty easy to pick the correct hole by counting.
Q: What's the longest focal length you can practically use
without needing an extension board?
A: I don't know. It's between 300mm and 450mm. My 300mm works without the extension and the 450mm needs it.
Q: How stable is the camera
with an extension board? (assuming keeping the tripod mount under the main camera)
A: Depends on the lens. With the 450mm f/9 Nikon in Copal 3 it's very front heavy. With the 450mm Fujinon C it's very stable and doesn't feel stressed or unbalanced.
Q: When is it important is it to measure bellows extension and factor it into exposure? Is there a favorite ruler/tape-measure everyone uses for this? (this being a general LF question)
A:
https://www.largeformatphotography.i...ws-factor.html It almost only comes up for me with macro, so I find the
QuickDisk very simple to use. I also keep a rolled up fabric tape in the bag.
Q: When I watch people doing LF work on YouTube, I basically never see them talking about this and/or doing anything about it.
A: It's rarely a concern for landscape or portraiture (except head shots on 8x10 and larger).
