  I suspect larger viewfinders are perfectly possible within the
  current prism dimensions (the prism does not magnify per se).
  However the higher the magnification the less bright is the
  resulting image in the viewfinder. The total amount of light
  entering an APS sized SLR is less than half the light a full frame
  SLR gets. The difference must be compensated somehow by smaller
  viewfinders but comparable in brightness. Even so I think the
  manufacturers have more stringent demands in optimizing light path
  to minimize light loss in an APS DSLR - and this could contribute
  significantly to the price.

  Servus,  Alin

And that's another plus for *istD - despite having the greatest
magnification of all APS-sized CCD DSLRs, its viewfinder is undoubtly of HP
type with 21 mm eye point.

AW: *ist D finder magnification

2004-01-04 Thread keller.schaefer
I don't know about the Canons but neither a Nikon F100 nor F5 would be an
alternative - they both have a .7 finder magnification.

Does anybody know how cameras with digital viewfinders (like the Minolta A1)
compare to this?

Hi Sven,

Yes, but the ME Super has no built in flash ;-) Those small viewfinders
are not a DSLR problem but a problem of modern SLRs with loads of
electronics and/or flash components in the prism housing. Actually you
have to buy a Nikon F100 or a comparable EOS if you want to get a modern
SLR with a "real" viewfinder.

I'm very satisfied with my *istD's viewfinder but it is also the
absolute minimum. I'm wearing glasses and maybe I would have bought a
Nikon D100 which is a great camera, too. But I wouldn't pay 1500-1800
Euro for a great camera with a viewfinder that I cannot use.


Cheers, Heiko
