On my housing the view through the viewfinder is to my mind is more or less unusable. All the screen information is so small as to be unintelligible.
With a mask on I can only imagine this situation will be worse.
I've only had the housing underwater once so far and that was really just a test dive and then I used live view. I think I'll keep using live view with this housing. But, undoubtedly there are going to be disadvantages to this.
What are the disadvantages of using live view? Two that spring to mind are possibly slowing focusing and shortened battery time.
Is there any way I can improve the viewfinder view or is this normal and something you learn to live with?
I don't intend to spend any more money on this housing other than on things that can be transferred to a replacement so maybe a 45 degree viewfinder is out.
Or, are there universal viewfinders that can be easily moved from one housing to another?
