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 have 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. 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.
The eyepiece extender fits the following Canon EOS cameras that uses Eg eyecups:
- 7D - Amazon | B&H Photo | Adorama
- 7D Mark II - Amazon | B&H Photo | Adorama
- 5D Mark III - Amazon | B&H Photo | Adorama
- 5D Mark IV - Amazon | B&H Photo | Adorama
- 5DS - Amazon | B&H Photo | Adorama
- 5DS R - Amazon | B&H Photo | Adorama
- 1D C - Amazon | B&H Photo
- 1D Mark III
- 1D Mark IV
- 1D X - Amazon | B&H Photo | Adorama
- 1D X Mark II - Amazon | B&H Photo | Adorama
- 1Ds Mark III
