FS7: Cinema lens advice for FS7 film shoot

I've actually been looking at the Cooke Mini lenses as well. A bit more pricey, but I wonder if the image quality would be worth it.
 
when I tried the Canon primes, I didn't notice any play while focusing.

Here you seem to be in a bit of a mix up. On one hand you want cine lenses, but still seem to think stills lenses would be OK for some shots. And you have not noticed problems with non PL.

As in the post above swapping between work work at the speeds required on a professional set as you may need feet in certain situcations and may be mungled by differing ODs for matte box if you use one.

As for noticing play.

You will see play when the lenses are driven by a powerful lens motor and rapic focus shifts are applied. Or even the calibration program of the FF.
Also you may have jitter if the camera is hard mounted maybe on a vehicle hood.
You wont notice play until you hit the extremes or test for it.

On play.. you need a decent foot for the FS7 to get it onto your tripod plate - zacuto made one I linked to in my 'rebuilding 2019' thread

You wont go wrong with a screwdown PL and a set of cookes - thats for sure - and that is one thing they buy -certainty.
Order them up move on to planning your lighting.

Okay, so I tested out the Canon Cine, Zeiss CP2, and the Cooke Mini, all at 50mm. When using the Canon with the EF Metabones adapter, I got a significantly wider FOV than I did with the Zeiss and Cooke, using the Metabones PL adapter. The images from the Zeiss and Cooke were practically the same, but I favored the Cooke slightly so I decided to book them for my shoot.

That's because you are using a speed booster for the EF lenses.

Yup. It was a tough choice also because the speed booster would have given me an extra stop which would have been great, but I'll deal with a 2.8 and just compensate with more light if need be.
