The large eye-cup fits the eye area with much more coverage than the original. Great if you wear glasses too. It was a very easy process to buy from Olympus Online. When shooting, this new Large Eye Cup is easier to concentrate on the subject without the annoyance things moving in your peripheral vision. It is very simple to exchange the small eye-cup with the new large eye-cup. The old one snaps off and the new one snaps in.

As a Canon shooter used to large and snug eyecup – this one provides it perfectly. Even in direct sunlight the fit and isolation of the outside light is just prefect. The challenge I have with this product is that the rubber edge is very sharp (from the molding during the manufacturing process) and irritates the skin around my eye. I’m shooting for 15+ years and never had this issue with any camera… I would not expect needing to use a chisel/sand paper and smoothen the product. Come on Oly you can do better!
