Solaris Camera Edit Aperture Issue Jan. 26, 2024, 9:30 p.m.
I just discovered my focal length was also set to 2400 ha!
Setting that explicitly to a 24 (as in mm) my aperture now also works as expected (36mm H Apt).
Totally correlates with the scene scale behaviour you describe. I do think Maya write did not catch the scale correctly it seems it indeed used cm's instead of dm's.
Many thanks!

Thanks Jsmack
That makes some sense. In my scene currently the prim value is reading for a horizontal aperture "36", and in the edit camera LOP "3600". Sounds like the prim is capturing the value as mm correctly.
The camera was actually created from Maya with a base scale of decimeters, which prompted me to check my asset scale so I think that explains why the Dof seemed off

Hi all,
Im using a camera-edit LOP to explicitly modify a cameras aperture - but the values seems totally messed up. Regardless if I'm defining H/V aperture or H aperture with aspect ratio - the aperture values seem to be bogus and require numbers in the 1000's.
Using values for example like 36x24 (expected unit of size - mm) completely results in broken focal lengths - and only when I use values closer to a 100 times greater, do I get an fov that seem appropriate.
For example:
If I drop a new node down - the greyed out fields state my camera is set to 20.955 x 15.2908. If I "Set all parameter values from USD primitive" using the "initalise parameters" option - It updates the fields to 3580 x 2013.75. If I enable "Control Aperture" those are the values needed to maintain the orginal fov.
What unit is this in and how do I adjust my filmback size to a known scale.
Followup question. What unit is fstop in, because that also doesn't appear to be a photographic ratio value - as it's producing massively too shallow dof imo for the value i'm specifying?!
