Well, I fitted the viewfinder last night.
It's very easy to do.
Just a matter of unscrewing the original, unscrewing a locking collar and pushing out the viewfinders holder.
Then inserting the Inon viewfinder and screw on its locking ring.
First off, this viewfinder is really good. It's a massive improvement on the original Sea and Sea one.
The view through the viewfinder
with a mask on is the same as putting your eye to the camera's viewfinder!
I took it in the pool last night, no leaks... The Inon viewfinder has double o-rings on it, whilst the original is a single o-ring.
It might take a little while to get used to the 45 deg, but Inon do make a straight one too.
The only issue I had is the length of the delete button on the DX80 housing prevents the viewfinder rotating to the right. The viewfinder is designed rotate through 360 degrees, indexing every 90.
What I've done today is remove the button, and cut about 4mm off the end of it to give clearance for full 360 degrees movement, however I'm sure lots of DX80 owners would be happy with the 270 with out this slight mod. If your normal portrait orientation is right hand down it's fine.
I'm very happy to have got this!!
