System Information
Operating system: Windows 10
Graphics card: NVIDIA GeForce GTX 1070

Blender Version
Broken: All Blender versions
Worked: None

Short description of error
When Alembic camera with "focal length animation" is imported into blender - there is no animation for focal lens - it stays same as first frame focal length mm
Same goes for Focus Distance (Depth of Field)

Temporal solution
The solution is to use Side program like Maya:

Import alembic with camera into maya;
Export camera as FBX from Maya;
Import Camera FBX into Blender;
Copy Animation of Focal Length and Focus Distance from FBX Camera to Alembic Camera.

A great solution would be if whyle importing Alembics - there would be an option to import it Localized, and also with desired framerate to chose.

This unfortunately is still under discussion in regards to how this should be implemented properly, see #54050 (Alembic: Camera properties (focal length, focus distance, ...) animation not importing), will merge reports.
