Top positive review

This adapter cost more than my first Canon camera

Reviewed in the United States on May 28, 2023

I got this for my EOS R and it fits and works perfectly. I thoroughly enjoy the variable ND filter being able to adjust it on the fly without having to switch screw-on filters which is frustrating and-time consuming. It is much easier, more convenient, and such a time saver.

The quality of this unit is typical Canon quality and works very smoothly with just a turn of the dial. You can also remove the ND filter completely and replace it with another, or with the clear glass filter if you prefer no ND filter at all. I with this unit came with the glass (neutral) filter as a standard so you don't have to purchase something just to fill the hole if you don't want to use a filter at all. This is really the only negative thing I have to say about it, other than the high price. I was shocked to see the price tag for this simple little adapter, which is more than I paid for my first Canon DSLR camera (a refurbished t5i).

Blue color cast, and adjustment wheel too loose

Reviewed in the United States on February 16, 2023

If you've read any reviews at all of this, you will have heard complaints of the dark blue color cast at max setting and an adjustment wheel that's so loose you'll be tempted to insert a piece of cardboard or something to make it stiffer. Believe these reviews. They're all accurate. You'll also have heard that it's unforgivable that Canon did not include a clear filter in a product of this price range. You can believe that, too.

So what you're left with is a deeply flawed product and a bad taste in your mouth, since you know that Canon is well aware of these defects but can't be bothered to fix them, which from a manufacturer's perspective would not require a great engineering effort. It would, I suppose, require a "Mark II" release and, with it, a tacit acknowledgement that the company released a "Mark I" version with such obvious flaws that they call into question the competence of Canon's engineering and quality control processes in the first place.

So would I recommend buying this? No.

Very good, but slight over-priced

Reviewed in the United States on September 25, 2020

Aside for the cost of entry, this is one of those things that just needs to work as expected to be very good. The image quality is excellent and build quality is very good. The only physical thing I would change is, I would like to have a detent or friction set into the rotation wheel to help it hold a position. As it is, it is very easy to rotate. Also, the final step on the ND stop range really plays with the color balance. I'd suggest staying away from the end stop (which is somewhere around 9-11 stops). Otherwise it has VERY neutral color. The last gripe is the cost. However, it gives you something that no other system gives you so there is a value to it. You just have to decide if this convenience is worth it to you.

Fix for blue shift

Reviewed in the United States on April 12, 2022

Verified Purchase

As other reviewers noticed there is a considerable blue shift on the denser settings. I found that a simple grey reference card to set a custom white balance fixed the issue for me. Of course you can also fix in post, but this solution is really easy.

Excellent Canon EF-RF adapter

Reviewed in the United States on June 20, 2022

The drop-in filter adapter by Canon comes with a variable ND filter already installed. The adapter works seamlessly with my EF lenses on a Canon R5c, and the variable ND filter works well, although it could benefit from click stops. AF and OIS all function without issue.

Game Changer

Reviewed in the United States on June 14, 2021

I love that I’m able to use the new mirror less canon bodies without having to buy all new glass. The built-in ND filter has been a game changer since I’m now able to have way more control over brighter areas without having to sacrifice the shallow depth of field. 10/10

Blue color shift *FIX*

Reviewed in the United States on July 23, 2019

First off, awesome idea by Canon. It's amazing and I love it for video. Makes life so much easier on all my lenses for run and gun stuff.

However, that horrible blue tint. For 399 you'd think canon would up the quality control. But for those of you who had bad luck but really need this product, I found the fix.

It's a simple matter of realigning the gear. In the picture I have the screw circled. Mark the spot on the filter part where the blue shift is gone, then unscrew the gear, put the filter case on max, then re insert the gear and screw it in. Now your max is set before the blue shift so you won't accidentally hit it anymore.

For Variable nd beginners, blue shift is generally common in variables with a wide range. It seems canon chose one of these but their qc would mess up on the gear stop that keeps the nd within its useable range. With his fix, you can now use your nd safely without worry.

Great Filter

I'm really not sure why the mount adapter and Filter together cost exactly the same as the filter alone. I bought it this way just to have an extra mount, but I really only needed the filter since I bought one with the polarizing lense.

Not worth it

Reviewed in the United States on November 21, 2023

This is Canon’s EF to R-mount adapter taking drop-in filters. I ordered it before remembering I had a similarly-functioning product from Benro. The Canon adapter came with just the polarizer and no clear filter as a placeholder when no filtration was wanted. Worse, I couldn’t get the included filter to fit in the adapter. So I returned it.

Decent Buy

Love the adapter & filter but i wish the clear filter was cheaper. If you have this and plan to shoot at night, you may find yourself doing what ive done and removing the filter and applying some kind of tape over the space to avoid dust entering. At minimum the filter seems like around 2 stops.
