I am nearsighted and am 75 years old, so I have several photos that are out of focus. You all must know how hard it is to get a great picture. So, when you try to capture the moment and clarity is not there it's not a good feeling. This snap on to the canon vision correction tool greatly helps the clarity of my images.

I ordered this for my wife with her vision and put this one and now she can adjust to focus for her vision.

I do not shoot with glasses on. The +2 diopter provided ample adjustment should eyesight keep changing. I can use manual focus again. To do over I would have up graded to the one with rubber eye piece.

It works well. I was referred to Adorama by the folks at Canon. They could not supply it. Good job!

Got this when I noticed that the settings info in the viewfinder were starting to look fuzzy and out of focus. After adding the +2.0 diopter to my EOS 80D, everything now looks perfectly clear again.

Not much to say about this device other than to say it works. It was a bit tricky to install. Instruction on instalaltion would have been welcome

I needed a diopter to correct my vision thru the lens for manual focus. My diopter adjustment was maxed out on the + side. My glasses provide a + 1.25 for my right eye. Adding the +2 diopter was perfect. I had to scroll the adjustment toward the -. I had plenty of adjustment room. For manual focusing it is great.

This corrective device will allow you to see the image that will be captured by the sensor without using eyeglasses. Just be careful when moving the camera in or out of a photo bag as it easily slides off and can be lost.
