But a little you have to rework:
1. Eyecup unscrew (3 small screws)
2. From the holder the "clamping spring part" (these are the two thinner plastic buttons, you immediately see what I mean if you have the part in front of him) cut off (carpet knife - be careful !!!).
3. Then you have to have the counterpart (on the rubber bead is mounted) cut away the "first level" of the plastic ring. Is very light with an attached horizontal knife when taking down the short rubber bead previously. Here you can see the object easily what is meant.
4. Re-assemble and - done.
That sounds more difficult than it is, it took me less than 5 minutes - including recovery of the screws :-)
Perhaps the hint helps yes some Samsung owners! Anyway, for me, a super substitute. It looks really good on the camera and is very convenient. The sensor for switching to the viewfinder will naturally not hidden!
