Canon Drop-in Clear Filter A Reviews

It's clear. It drops in.

Works as expected. Optically clear, has no effect on image quality. Perfect for when you do not need to use the variable ND filter. Not sure why it's so expensive.

A little bit expensive

For what they do really is expensive. I will prefered a frame with any glass.

Must have but stupid expensive for what it is

Title says it all. It's just a clear glass and unfortunately, this clear filter is ABSOLUTELY REQUIRED for the drop-in filter adapters to work properly. At an additional $130, I think it's absurd to sell this separately from the adapters.

Works As It Should

While this works as it should, it has little utility for me. Because the design of mount adaptor in which this fits requires that adaptor to be removed from the camera and placed upon another lens before re-attaching it to the camera, I find myself either using an adaptor without interchangeable filters, or using the filtered version, rather than the clear insert. I would advise that anyone considering buying this first buy a mount adaptor without a filter, which would cost no more for a Canon and less for another brand, before or instead of, buying this.

It seriously needs a better case

For such an expensive filter, it needs a better case. It comes with a petri-dish kind of screw case that has pads that fall out. It's totally unsuitable for using outside of a studio. I ended up buying a custom made case on Etsy instead which is awesome. Also, the adjustment wheel is so loose and needs some dampening to keep it from moving so easily.

Drops right in and pulls right out with ease. I don't think I;ll ever get RF lenses since these adapters are so awesome

Good job

Timely delivered filter - allows me to use my Astro modified camera effectively. Good job ...

No issues so far

I'm not convinced these seal flawlessly. in terms of keeping out dust when installed. But it seems to be fine. I prefer using this instead of changing the entire mount out when not in need of a drop-in Pola or ND.

I am more concerning about the image quality and autofocus speed when using this clear filter. Does it degrade the image quality of the captured image? Does it slow down the autofocus speed at all?

Why not use a snug fitting $5 rubber lens band over the slot when a filter is not desired instead of using this $130 piece of clear glass?

The drop in adapter is .1 inch thicker than the other Canon adapters. From my test, taking out the filter significantly affects the focus range.

Why does it even need the glass? Should just be the slot cover. More glass = more potential for flare.

Even though seems useless you need it. Don't get the covers sold in amazon since without this your lens will not reach infinity focus below 35mm, as one of the answer says, fixes the optical formula due the thickness of the VND or CPL..

Does this come with a case or pouch for the filter? The ND RF/EF adapter does not have anywhere to place the filter when it's out.
Asked by: Christopher
It does come with a plastic case than it can be stored in, if you want more protection, could always get a mini hard case for these as well.
