WORK PERFECT

I have had zero issues with this adapter & filter. Zero! I compared it to a friend of mine who has a really expensive one and I honestly can't tell the difference. I'm so glad Mike came out with this. It literally saved me so much money and works great!
great accessory

As you need an adapter for EF lenses to RF mounts, this is a great accessory that adds a lot of 'value' to using the EF lenses, since the VND filter allows you to do long exposures for blurring water e.g., w/o having to use a large diameter VND on the front of the lens. Plus the polarizer works similarly. The 'fit' with the red ring seal is very tight, which I hope does not wear out or cause problems in the future, so giving this a 4 stars.

Is there a way to secure the adapter when using larger (cinema) lenses?
There's no screw-in lens support, so use rails with lens support to secure lens to lens adapter/camera and hope for no wiggle. Test focus before hand of course. It locks tight, but it's not a secure locking lens mount for cine.
