Hi
I've been using the RS2 with a BMPCC 6K, but this will now be used almost permanently with a handheld rig.
I have an up to £3K budget for a camera to use specifically with the RS2.

Ideally, it would be a little less cumbersome than the BM, be at least 4K, a decent sensor size and capable of using EF lenses (or be cheap enough to buy with a decent non-EF lens).
I have some legacy lenses too so maybe even something with an adapter

All suggestions considered.

Thanks!

Have you considered an canon R5 with the EF adapter?

Thanks.
Had a look and out of budget.
Currently looking if I can stretch to a Sony FX3 with adapter.
