After poring over dozens of reviews and watching countless comparisons on YouTube, we think we’ve finally landed upon an ND filter adapter and drop-in filter system that (1) is compatible with the RED Komodo; (2) whose solid NDs have remarkably neutral color rendition; and (3) that won’t break the bank. Kolari is asking $224.99 for the EF-EOS R Drop-In Filter Mount Adapter with clear filter while individual drop-in NDs are selling for $129.99. The only catch is that, like most other adapters practically everywhere, they’re on backorder. If it turns out that Kolari’s drop-in filters are compatible with Meike’s $159.99 MK-EFTR-C adapter, you can save an additional $65.00 and get a Meike variable ND and clear filter thrown in. Not only that, but Meike’s website says their adapter is now in stock. Regardless of which adapter and drop-in filter you eventually settle on, it’s always a good idea to confirm that they’re in stock before placing your order.
