Bluestar Round Extra Small Microfiber Eyecushion (Blue)

I use this to make an otherwise usable C100 EVF quite usable. I thought it would be a temporary fix, but it works well enough that instead of looking for a better solution, I just bout a backup. At this price, why not?

I've been using this for a few weeks now on my Canon C100. It does fit over the EVF which is great but when I first put it on it was tight and now it's a lot looser. I'm really not sure how much longer it will stay on without becoming too loose. My camera case is a tight fit for the camera so it comes off when I put it away. Also, because it's round, it doesn't really block out 100% of the light from the outer edge of the side of my head. Not really surprising but worth noting. OK now the good. The price is amazing, it's really nice, soft, material and it does make looking through the C100 EVF MUCH better. I might actually be the only person who likes the C100 EVF though. I've used the C500 and the EVF on that is obviously much much better but going back and forth between them I still didn't hate the EVF on the C100 even though I thought I would. Bottom line, it's a no brainer purchase for the C100. For less than your camera becomes more usable especially for hand held shots because it still stays small unlike adding an additional monitor or EVF.
