Canon EF-EOS R Drop-In Filter Lens Mount Adapter with Circular Polarizing Filter

Well made, and excellent fit. I shoot outdoors often, so the filter is an essential element. My EF lenses work great with the adapter.

does not work on Canon 24 1:1.4mm II L and Canon 8-15 1:4mm L lenses. Does not focus on objects further than 1.5 meters. This is not indicated anywhere in the instructions or description! That's why this thing turned out to be useless for me. I do not recommend buying

Highly recommend if you don't need a locking adapter.

Using my EF 11-24mm F4 lens with polarizer works great, and happy to be able to continue using this lens on R mounts.

The next step in this adapter's development is the ability to use 2" telescope or other filters interchangeably by screwing them in and out of the drawer.

Works great, making it possible to use all of my EF lenses. Also being able to use one filer for all lenses is great.

Very handy way to have a filter all the time. Nice and securely attached, not likely to drop out. Recommend to all that shoot EF glass on R cameras.

I was a bit concerned that the adapter is actually a part of the optical formula, this is because it is a bit deeper in depth than the other two Canon offerings and the added depth prohibits the camera from focusing to infinity without an optical correction. I am happy to report that I have been thrilled with the results I have gotten while using this adapter, of course I also have adapters without the CPL or filter slot. I have read a few reviews where people are complaining about having to purchase an expensive UV filter to use when not using the CPL, my approach was a simple one and not nearly as costly, I just bought an additional adapter without the filter, problem solved!

Worked better than expected and allows for continued use of my older EF lenses on my EOS R series cameras. This adaptor with the drop in filter (allow me to be more creative using my other lens instead o buying different filter sizes and continuously screwing or unscrewing my filters from the ends ends of lenses

This lens adapter works perfectly!! It’s a snug fit and no loss in AF. The drop in filter is a great feature that will come in handy on many of my on location photo shoots. I love it!

Works great with all the EF lenses on the R6 camera. The Circular Polarizer if very useful for all the landscaping shots... switch lenses and the sensor is protected by the drop-in filter.

I just needed an adapter but none of the basic ones were available and I thought the drop-in could be useful some of my EF lenses that I don't have CF or ND filters for. I love the drop-in idea to avoid so many random pieces or different sizes in my camera bag. While it serves its basic purpose of connecting my EF lenses to my EOS R5, there are some issues I would not expect in premium gear. A minor issue is that the CF wheel spins too freely and could use a little more tension to facilitate precision adjustments and prevent accidental adjustments. More frustrating is that you have to have a filter in the unit. There is not a simple cap so you have to buy an extra "clear filter" that serves no purpose what-so-ever and still puts an extra, unneeded piece of glass in the path. At least with a clear filter on the end of a lens, you can argue protection, but as a drop-in this just impacts image quality and costs me more than the price of the plain adapter. The adapter should have come with a cap or blank so you could also use it as a plain adapter with needing to spend a lot more money. Relative to the market for these accessories, it should have shipped with a CF, ND and cap or clear.

I'm confused why this would not come with the clear adapter? Who wants to adapt their lenses and not be able to shoot without a polarizer? Plus, the clear filter is on backorder everywhere, can't get one. Now I have a new camera I can't use, unless I plan on shooting with a polarizer all the time? The product description needs to make this VERY clear.

Gives an added dimention to EF lenses which have a very large diameter filter thread or none at all allowing you to put a neutral density or polarizing filter between the camera body and the rear element of the lens negating the purchase of expensive special filter kits.

Game changer for sure. Love that I now have a filter that will work on any of my lenses regardless of the diameter.

it wasn't the product i had hoped it was. Canon needs to create an ultra adapter that comes with 1 blank adapter 2) polarizer 3) GRADUATED FILTER 3) high density neutral. maybe even a whole line up. I know they have a clear but clear doesn't make any sense when none would be the preferred situation. canon offers a blank holder for the big white lenses. You can put gels in there, nothing or anything.

This adapter is a great solution to not only adapt all of my EF lenses to my newly purchased EOS R, but to also add Circular Polarization capabilities to all of my EF lenses without the expense of purchasing individual filters for my numerous lens collection. The task of removing lens hoods to adjust the Circular Polarizer is also eliminated. With that said, what I find completely unacceptable is the excessively high cost of the clear adapter, which should be included in this combination for no additional charge! $129 for an accessory to an already pricey adapter, that does nothing more than fill the space when not using the Circular Polarizer is obnoxious!

After years of reflexively adjusting a PL filter by reaching to the front of a lens, it will take a little practice to get used to making the adjustment at the very back of the lens & adapter. That aside, it’s going to be wonderful not to have to carry different size PL filters, and even better to be able to use the lens’ hood with a polarizer. The adjustment action is smooth as butter, and the build quality is excellent. It’s not inexpensive, but in the long run will more than pay for itself in terms of convenience.

When I received this piece I was skeptical of its capacity. So I took out immediately to a lake out my back gate. Water is usually a I good test bed for specular reflections. This filter performed better than expected. When I downloaded the pictures I was very pleased. The water was clear and the sky was enhanced. In another note, this piece keeps me from buying multiple filters for use on different sized lenses . . . every EF lens that I own will fit perfectly. what more could you ask?

I use ultra-wide zoom for real estate photography and its always been a hassle to find a way to get a polarizer filter mounted. This is a perfect solution. Only thing left to confirm is that I can get the ND filter without having the purchase the whole adapter.
