What will my Sinar F2 4x5 do that a Chamonix 4x5 or Ebony 4x5 won't

[Ed Richards]

While it can cost as much as an f2, a Sinar pan-tilt head makes the Sinar really fast to use.

I'd rather do macro work any day of the week with a monorail rather than with a folding field camera, but I have learned how to successfully do it with any of em.
Same goes for architecture.

You could also consider the Arca Swiss F-line. It is very portable and has all the benefits of a monorail :-)
