Canon EG Eyecup (1 Viewer)

I am currently looking to replace the rubber eyecup on my canon Eos1d mk4 and believe the correct eyecup is the EG version.
However when looking to place the order I notice 2 different options available.
The first approx £9.99 being what I assume is a std rubber eyecup.
The second approx £29.99 looks identical but is sold as a Dioptric adjustment lens for those (like me) that normally wear glasses etc.
While I understand the need for Diopter adjustment I am a little unclear as to what eyecup to buy as the camera itself has the facility to adjust the diopter underneath the eyecup anyway !
This being the case I would have thought that the std eyecup would suffice but I guess I'm missing the point regarding the more expensive option.
It may be that the diopter adjustment on the camera doesn't allow enough adjustment for some users maybe ?
I would therefore appreciate any feedback before placing my order for a replacement.

Thanks

Hi Eos9

A quick reference to page 40 of the User Manual shows that there are 2 Eye Cups. The standard one works as normal and uses the camera dioptric adjustment button. The second one, the EG, is used to provide additional adjustment if the standard set up cannot provide a sharp image.

Have a look at the following for an explanation of Canon's Dioptric Adjustment lenses www.eos-magazine.com/articles/viewfinder/dioptric.html

Having read the article its pretty much as I suspected with the more expensive eyepiece being used only if the 'in camera' adjustment isn't sufficient. Answers my question perfectly so I'l opt for the std eyepiece in this instance.

Thanks for the info Shane - much appreciated
