I would try it
However the last electronic viewfinder I looked through was ... so very artificial.
Like a tiny TV that was too close and too bright. But I'm sure if manufacturers wanted too they could make very nice electronic viewfinder
Opposite of that, I have tried an external finder on top of an AF camera and that was surprisingly nice, with 200% coverage (approximately) but at closer than 4 feet (approximately) parallax becomes a real problem.
Ultimately manufacturers need to take interest in viewfinders again, they are so concerned with megapixels and face detection they shelved they've got us looking through little keyholes to compose our shots.
I am convinced that sucky viewfinders encourage thoughtless composition, or impair thoughtful composition. I really enjoy using the old manual film SLR's with their big bright viewfinders. How could we have lost that? How did technology march forward but get worse? That's a rhetorical question but I still think about it
It looks like for now we'll be squinting through our little keyhole finders and composing on the LCD like Moms do it
That's my 2 cents
Cheers,
Craig
