Assuming you need to do camera tracking, definitely shoot lens grids for
every prime lens and if you have zoom lenses try to shoot grids at
regular intervals. If you have the luxury and patience, shooting at
different focus distances will help you assess lens breathing.
Make sure you have a solid tracking solution, lidar scans help shit
loads to camera track things.
Remember that spatial filters like blurs (=glows etc) should be applied
with the respective anamorphic aspect as well. Bokehs are egg shaped
rather than round. I think Nuke's defocus nodes have to be set to aspect
0.5 rather than 2 to produce the correct shape.
I'd shoot out-of-focus reference plates as well to remind yourself and
others and possibly even steel kernels from if you want to build your
own bokeh effect to match plates.
DOF will be shallower than usual, since the horizontal fov per focal
length will be twice as wide, so be diligent with tracker markers.
Again, tracking is harder due to all these things.
I wouldn't flatten the footage to square aspect. Working in true
anamporphic will help remember all of those pit falls and preserve the
lens geometry if you need a decent lens distortion solve in the camera
tracking process. I found in the past that flattening plates, then
tracking them in PFTrack yielded inaccurate lens models, whereas leaving
the distortion and setting up the tracking environment accordingly
produced better results.
Don't rely on nodal moves. An anamorphic lens can only be nodal wither
horizontally or vertically, i.e. for pans or tilts, but not for both.
Have the camera assist mark both of those on the camera rig so the
camera can be adjusted quickly if you need to rely on minimal parallax.
However, in real life there will be lots of focus pulling and because of
the lens breathing nodal moves will be near impossible to get.
Shoot reference for lens flares (mount torch on c-stand and pan tilt the
camera to get a feeling for the flares behaviour.
Enjoy the cooler look ;)

Going to start planning on a 4K anamorphic feature film. And I must
say that I don't have too much experience working with anamorphic plates.
Are there any issues that I should take note of or any other
considerations?
