Indeed. Having seen the Sinar setup, they are obviously interested in getting the very best out of the camera, providing for being able to use bellows as a compendium shade and providing adjustable cropping blades for the front of those bellows.

For GPS benefit, I will reiterate that, without going to the extent of the Sinar system, the Lee hoods are a reasonable compromise, but there have been times when I wished I had a "compromise" compendium with adjustable masking as well.

When using a field camera, there always tend to be compromises, like weight versus rigidity; the length of a compendium is another.

In this LF world, sometimes we have to forego "technical perfection" in favour of being able to carry the camera bag without injury.
