Canon EF-RF Lens Mount Adapter List for EOS R Series Mirrorless Cameras

With the release of Canon's new full-frame mirrorless cameras, the EOS R5 and R6, the EF-RF lens mount adapters extend the range of compatible lenses designed for attaching any EF or EF-S-mount lens to the EOS R-Series mirrorless digital camera. Canon offers four different version of the adapters:

• Canon Mount Adapter EF-EOS R (MSRP $99)
• Canon Control Ring Mount Adapter EF-EOS R (MSRP $199)
• Canon EF-EOS R Drop-In Filter Lens Mount Adapter with Circular Polarizing Filter (MSRP $299)
• Canon Drop-In Filter Mount Adapter EF-EOS R with Variable ND Filter (MSRP $399)

These adapters are either hard to find, have a long back-order whether it be from Amazon, B&H Photo, Adorama, Canon's online store or even price gouged on eBay.

However, if you are in need of an EF/S-RF lens mount adapter immediately for a project or vacation, there are other alternatives from 3rd party manufacturers. The adapters retains full auto-focus and image stabilization capabilities and contains no optical components, thereby maintaining the original optical quality of the mounted lens. The only difference between OEM and 3rd party is the material quality and added lens/tripod collar (if applicable).

We've compiled a list of brands and where you can purchase them. They don't break the bank like the Canon or the price gouging from 2nd hand markets but it will hold you over until you're able to find an Canon version or if you feel the need to get OEM. You never know...you may end up liking the aftermarket ones and save some money.

If you find any additional adapters that we may have missed, please let us know.

BACK IN STOCK: 3D Print Canon Eyecup Eg Eyepiece Extender for 7D 5D 1D Cameras

One of the most popular/visited reviews on our site is the JJC EC-6 Eyepiece Eg Extender. If you're not familiar with the eyepiece extender, it extends the eyecup 5/8" (15mm) from the camera body. This is useful for eyeglass wearers and others to keep the tip of the nose from touching the camera screen. Canon does make their own EP-EX15 and EP-EX15 II eyepiece extender but they don't fit any of the more recent EOS cameras.

We have been getting emails on where the aftermarket eyepiece extender can be purchased from. Unfortunately, they are discontinued and no longer being made even though the Canon eyecup (Eg) is still being used on current and new Canon cameras.

To help other photographers out who are searching for this extender, we created a CAD file (from scratch) of the eyepiece extender which will allow us to print a 3D model of it. The 3D printed version is almost an exact duplicate of JJC version but with some slight improved modifications:

• Aftermarket : The 3rd party extender came with its own eyecup with a flat back which is slightly different from the Eg eyecup that comes with your camera.
• 3D Printed : Grooves were cut out so that the OEM (Eg) eyecup that came with the camera can be used without have to buy new ones. If you lost or need replacements, you can purchase from Amazon, B&H Photo and Adorama.
• Aftermarket : The 3rd party extender came with a cheap plastic lens to "help" magnify your view.
• 3D Printed : Sole purpose of this is to extend the eyecup so that your face is not near or touching the screen. Also, the plastic lens only made your view even more distorted.

One thing that will still be the same is that some of the corners may be cut off when looking through the viewfinder because your view is now further away. Also, the viewfinder and OEM eyecup is rectangular while the extenders opening is a square. So this will require you to make slight adjustments to the positioning of your head when looking through the viewfinder.
