Well, yeah, I guess back in 1949 they didn't get too bothered about a tiny, squinty eyepiece or the fact that the field of view is only fuzzily defined -- most camera viewfinders of the era being similarly afflicted.
But if you want to see a REALLY nice zoom viewfinder, you've got to dig up the one Canon made. The image is brilliantly sharp (and unlike the Tewe's, doesn't change focus as you zoom) and the edges of the field are sharply masked, like those on a Zeiss turret finder. The eyepiece is reasonably large and has a diopter adjustment.
But of course it's a wildly pricey collectible today, and doesn't cover as wide a range (my Tewe goes from 35 to 200; my Canon only covers 85mm to 135mm. Canon made a wider-range model, but that required two tiny zoom lenses on a turret, and is even costlier now.)
Still, it was a great idea, and something that probably would have a lot of utility for RF users today if someone would produce a modern version. Paging Mr. Kobayashi...?
