Among the many points with choosing up a mirrorless or mirrorless-style digicam for video is that they lack the house for among the {hardware} that’s widespread on conventional cinema cameras – like inside ND filters.
Now, most of us solved this problem with different varieties of NDs, normally positioned in entrance of the lens. That doesn’t imply that the dream of not having to fret about swapping filters whenever you swap lenses doesn’t stay.
For shooters with Canon RF-mount cameras there could also be an answer. Josh Sattin exhibits off a Meike adapter for EF-mount lenses that options an built-in variable ND filter. That may make life simpler.
The Fundamentals
Already talked about however price going over once more is the essential performance of this machine. It’s a lens adapter for utilizing Canon EF glass on Canon RF-mount cameras.
This does imply it’s not an possibility if you happen to had been planning on utilizing native RF lenses.
Inside this adapter is a drop-in filter holder and it comes with a variable ND filter. When put in you should utilize a dial on the surface of the adapter to regulate the ND energy.

If you’re planning on utilizing EF lenses and tire of swapping out threaded ND filters then that is excellent.
Meike claims that the included filter has a really huge 1.5 to 9-stop vary.
As for worth, it’s on the reasonably priced finish at $160. Examine that to the official Canon providing that runs $400.
Picture High quality
Whereas the adapter itself isn’t going to impression picture high quality, the glass of the filter will. There are some things to be careful for:
- Shade shift
- Vignetting/X patterns
Utilizing an EOS R5 with the EF 16-35mm f/2.8 III he carried out a number of checks. The wide-angle ought to pressure all features of the filter.
He in contrast it to the NiSi True Shade Variable ND Filter examined to be the most effective with reference to paint shift.
Wanting on the samples you may inform that Meike has a hotter tone. It’s not horrible and does look like simply correctable in put up or with a customized white stability.

Impartial Density Vary
Going from 1.5 to 9 stops is an enormous vary for a single ND filter. Most stick between 3-5 stops whole to keep away from the worst points with colour shifts.
Doing a take a look at it seemed like that vary was correct. And if it was inaccurate then it might be that it really has a little bit additional density on the darkest finish.
Autofocus Efficiency
Typically, you gained’t get top-tier autofocus efficiency with an adapter. A part of that’s that EF lenses are a little bit older and never fairly capable of carry out on the pace of the newest R-series cameras.
On this case it doesn’t look like AF is impacted negatively by any severe quantity. Newer lenses will clearly carry out higher although and as with each Third-party adapter, there’s potential for some weirdness.
Clear Filter
The adapter really comes with a transparent filter along with the ND filter. It doesn’t seem to have an effect on picture high quality.
Why would you utilize this? A few causes really. It retains the opening on the facet of the adapter crammed in to forestall mud and light-weight leakage and it retains the sensor coated when swapping lenses.
Construct High quality
Construct is much like the Canon adapter and it’s made out of sturdy plastic. There’s a climate sealing strip on the rear mount.
The variable ND filter dial is tiny although and may make exact changes tough.
In any case of this testing Josh simply recommends the Meike adapter in case you are in search of
