No problem whatsoever - for me: I got rid of my F4S because it never auto-loaded properly on the first try; I had traded away my F and F2 Photomic by this time, and to get rid of the F4S I went backwards to the F3 which was better, except that unlike my other, older Nikons, without a battery it was stuck with one useless mechanical speed. I think the F2 was the final Nikon film masterpiece.
That F3 camera was almost never used, and I still have it today, where it lives in the dark beside my Minolta Flashmeter 111. Regarding the consumables: for 135 colour it had to be Kodachrome 64 Pro or nothing.
Those were the days!
Happy New Year, Francisco.
