Filter Systems: trying to standardize

[r.e.]

On the B&H site someone asked if the Sensei adapters are compatible with the LEE system and the response was”no”. See here for example: https://www.bhphotovideo.com/c/product/1119082-REG

Ha! I should have read more carefully. I didn't know that Sensei makes its own filter holder, which it calls a "100mm universal holder". Sneaky marketing, for people like me who aren't paying attention
