If you are moving from one DSMC2 body to another, your filters remain compatible. Only the VV upgrade requires a change of OLPF size.
If you have upgraded from DSMC1 to DSMC2 your filters will need to be replaced.
There is a strong secondhand market for all RED accessories, however we can offer loyalty discounts for those wishing to trade-in and upgrade. Contact us directly for a discount code.
