Slow day at the Walmart, Mercer?

Just remember that if you damage the evf while cleaning it and try to explain it to Canon the CPS lackey will Tell you that you should have sent it to them to be cleaned. With the very gentle cleaning I performed, I never thought I would damage mine. This design is a failure and Canon are standing behind it because, at the end of the day, they would rather lie and take your money again to fix their mistake. Corporate greed.

Quoted from: http://www.dvxuser.com/V6/showthread.php?354171-C300-Mark-II-viewfinder-coating-all-screwed-up-u "... I have to say that that is just F'n ridiculous. Even for Canon... That was just poor engineering. That should be an easily(user) replaceable service part that is $50-$75 max." Right. And if Canon engineering puts a coating on a viewfinder I would never expect it to flake off with just one light cleaning. And as I've said: "... wouldn't it be wonderful if Canon would have coated the 'inside' of the EVF screen with their flimsy luminescent blue coating so you wouldn't have to deal with such an asinine design while preforming a standard cleaning practice that you've done a hundred times before on other cameras?" And if you do scratch this poorly designed (failed) part, the nameless corporate drone at Canon will tell you that you should have sent it to them to be cleaned at your expense. Canon earned 20 billion dollars last year and the CPS rep saved the company 20 cents... bless his tiny heart.

@JCS As I have mentioned, there are many different report on what constitutes the best way and best materials to clean with. With all due respect, this guy says the opposite of what you have mentioned with regards to microfiber cloths.: https://www.youtube.com/watch?v=dAa-cdtildo. To be clear, I am not in the habit of 'scrubbing' Qtips across delicate optics. @ Tugela Good quality lens solution contain methanol, not alcohol. For those who do scratch off the luminescent blue coating on their EVF screen, another owner who had this happen to also has explained that he removed the EVF assembly, took out the screen and polished off the rest of the blue coating so that it is totally clear. Sorry Canon, you don't get my cash a second time. My feeling is that the luminescent blue coating is designed to knock back damaging sunlight that may damage to EVF internals. If so, and with it removed, care should be taken to prevent direct sunlight from entering the EVF. Care should be taken regardless. And finally to all those who will eventually come forward with the same problem, wouldn't it be wonderful if Canon would have coated the 'inside' of the EVF screen with their flimsy luminescent blue coating so you wouldn't have to deal with such an asinine design while preforming a standard cleaning practice that you've done a hundred times before on other cameras?

Hi JCS, thank you very much for your contribution. I found a replacement part here for £119.62: https://cvp.com/index.php?t=spareParts&partSearch=DG3-5788-000&manufacturer=4 One can't just buy the blue screen, but the entire assembly. On a side note, there is a lot of different information circulating on what is the best way to clean lenses (which I assume carries over to other sensitive optical parts like EVFs) and with what materials. Some suggest different kinds of microfiber clothes while some expressly warn against them, breathing on them is not recommended as breath may carry digestive enzymes. This the method I employ, it is informative if you can get past the presenter: https://www.youtube.com/watch?v=nUSUIbhh4TA

Hello everyone, So I'm out in the field a lot and the EVF screen on my C100 MkII eventually got dusty as they normally do. I decided to gently clean the EVF screen with a Qtip and Eclipse Optical cleaning fluid at which point the thin luminescent blue coating began to flake off. It is now difficult to see through the EVF. I contacted Canon (CPS) explaining the situation and and they said that because I cleaned the EVF myself I was at fault because the camera has to be cleaned by their service department which in my view is absolutely ridiculous! How can they expect cinematographers working in the field to ship their cameras to their service departments for a simple cleaning that normally takes no more than a few seconds. This is a serious design fault that reminiscent of Apple's 'Staingate' issue and Canon is trying to hide this by saying that it has to be cleaned by their service department. I'm sure many owners will now be coming forward with the same issue. So I'm curious to know if there are others out there who have experienced the same issue and if so, how was it dealt with by yourself and Canon? I've had many cameras in my day and this is the first one that I've seen that has this luminescent blue coating on the EVF. Has anyone ever seen a luminescent blue coating on an EVF on a camera other than the C100 MkII? Can anyone make a comment on how you normally clean your EFV?
