What, you think it just didn't occur to them? There are reasons why mirror-based DSLRs have persisted, e.g. sucky electronic viewfinders and the slothlike speed of contrast-based autofocus. Eventually the technical problems will be solved adequately, and EVF designs will probably take over (hopefully with something better than Oly's 4:3 sensor). -Miles -- `The suburb is an obsolete and contradictory form of human settlement' |

There are market forces at work that will make this happen, eventually. In the meantime, there's a lot of legacy glass out there, and legacy production lines that can make pentaprism-based cameras very cheaply. This will take years to go away. When it does, digital photography will take another quantum leap in quality, price, and compactness. As an example, consider the advantages of a non-planar sensor that is built into the rear element of a lens, a variable density sensor that provides constant pixel density over a digital zoom range, non-rectangular pixels, or bayer-style patterns with more than three colors - perhaps extending to UV and IR. -- Mike Russell - http://www.curvemeister.com |

And EVFs are for losers. |

When it does, digital photography will take another quantum leap in quality, price, and compactness. you have that backwards. the technology needs to make the leap before optical viewfinders are replaced. evfs are currently too slow, especially in dim light and phase detect autofocus is much faster than contrast detect. you won't be able to have a 9+ fps camera like the nikon d3s with evf and contrast detect autofocus any time soon. legacy glass is irrelevant, that could still be used on any camera, optical viewfinder or not. As an example, consider the advantages of a non-planar sensor that is built into the rear element of a lens, curved sensor? not gonna happen. and where's the rest of the circuitry? a variable density sensor that provides constant pixel density over a digital zoom range, how is that going to be made, let alone work? non-rectangular pixels, nikon tried that, what a mess. or bayer-style patterns with more than three colors - perhaps extending to UV and IR. already been done, and very few people want uv/ir sensitivity. |

Say an interesting article recently that observed that people
with cameras with optical viewfinders and that used them had a significantly less picture failure rate. Why? Because it is not natural to hold something out in front of you when taking a picture and such a stance is inherently unstable. Hold the camera up to your eye and it and you are both more stable, there is less chance of the camera moving when you press the shutter release, and as you will likely hold the camera there until after the picture has been taken there is less likelihood of moving the camera during shutter lag. Ergo, less failed pictures. My wife used a Konica Minolta S2 (IMSMC) which had a screen and an EVF. Her picture failure rate with the screen (the poor resolution of the EVF proved to be annoying) was awful: now she has a Nikon D50 and has yet to have a pic fail. -- Woody harrogate three at ntlworld dot com |
