Pentax Eyecup EC107 Digital Camera Review

Annoyed that the 645z only has one eyecup option and it's quite a loose fit (hence the replacement) but very comfortable to wear even for long periods of time. Without them, the camera is dangerous.

I prefer this style of eyecups on all my cameras. They are much more comfortable and make it much easier to focus in the viewfinder. Another benefit is that any extraneous light is blocked as it matches your eye. I use them on Pentax 645N film cameras and they fit and mount easily. When inserting the film holder, only hold the bottom edge of the cup. never mind
