Should I buy a full prime lens kit for my FX6 or build a set over time?

I’m a filmmaker currently rigging out a Sony FX6 as I continue learning cinematography and working toward shooting and directing feature films that I write.

I’ve been considering investing in the DZOFILM Vespid2 T1.9 Prime Lens Kit (18, 24, 35, 50, 85, 105mm). In theory it seems like a great all-around set that would cover pretty much every focal length I’d need for narrative work.

My thinking is that having a consistent set of cine primes would help me learn composition, blocking, and lens language more intentionally rather than relying on zooms.

That said, it’s still a big investment and I’m wondering if there is a smarter way?
