Fits the need excellently with quality build and results

Purchased this as soon as I heard about it, as the hope was it was good enough quality to compete with the Canon version - and a worthwhile gamble.

Purchased with the VND for use with wildlife video and Warbird photo/video. I had rented the Canon equivalent in the past and can say the build of this unit meets/exceeds the name-brand, and the quality of the filter superior. I haven't experienced any color casting when using the filter. I also appreciate the "clear" holder being empty and not just a clear filter glass unit. Dust protection has held up with no issues while shooting on trails or next to airport taxi-ways.

The only regret was I didn't purchase the CPL and Spare holder before their prices jumped on those accessories (I wanted to check the optical quality of the VND before ordering and waited a day too long)

Meike does it again! Excellent!!

I had been wanting a drop-in filter adapter and the Canon adapters have been hard to come by and are expensive. I was so glad to see Meike release their adapter as their standard adapter has been perfect so far. This does not disappoint and allows me to use a CPL with all of my Tilt-shift lenses which are normally difficult to mount. The built and materials are excellent quality and it has sharp looks to boot. The filters snap in positively and aren’t loose. And oh yeah…this is fully compatible with Breakthrough Photography, and I assume, since the two are interchangeable, the Canon brand drop-in filters as well. Although I mainly purchased this to use with CPL filter, The VND this came with seems neutral and is great for video on an R5, making adapting my Meike EF Cine lenses even more versatile. I’d recommend this over the other adapters based on build and function any day.
