Ultra Primes and Zeiss Standard Speeds - mix

I've recently shot some more home movie footage and mixed Zeiss Standard Speeds with Ultra Primes. All natural light and different time of day and two weeks apart.

Has anyone shot properly lit narrative using both and can you get away with it? ? I'm asking because I've got a short film in the planning and I am missing two focal length from my Standard Speed set but have those as UPs.

I think it may well be fine, at least based on these images. I think in a perfect world you might want to shoot some charts and audition some diffusion in front of the ultra primes if they are reading too sharp when compared to the standard speeds

Thanks Robin, good idea, I might just do that. I recently watched Fargo and considering that the film was shot with Standard Speeds, it looked extremely sharp to me.

I would set up a good digital camera with vectorscope and waveform monitor and charts and switch the lenses back and forth without changing camera settings. Record some footage (ideally prores for easy and reliable post processing) and compare afterwards with scopes if needed.

You should get good idea if lens is warmer or colder than the other, how the contrast differs and can compare the edge falloff etc too. 

If you have mirrorless stills camera with pl adapter you might be able to use it for tests if that is easier to arrange.

But the point being, digital camera always for comparison tests to get immediate test result with scopes and to make sure film processing does not affect the results
