SLRs Make Less Sense With Digital ?
The SLR was a great idea when needed to have a seperate path for
viewing and film exposure, but with digital, the sensor can be the viewing as well as the recording medium so perhaps less need for a seperate path via flip up miror ? |

With the FF MILCs it is also a market Nikon, and Canon have finally entered even though they did so 5 years late. They still have a way to go to catch up with Sony in that market, and they are not even contesting the APS-C, or M43 MILC market. -- Regards, Savageduck |

Thanks for good info.
Like I suspected. |

It depends. First, to drive two digital outputs (display + data recording) requires the product to have more power ... both computational power and literal power (battery). Second, an LCD display isn’t always a good thing to view through, as there’s lag for example, which degrades tracking performance of moving targets. The classical optical path operates at 186,000 miles/second, which is a few femtoseconds, whereas the digital display replacement requires photon to electron reception on the CCD, followed by a data read, then data transmit, data processing, another transmit, & finally to be redisplayed. Even with current technology still takes bunches of milliseconds...and try to see where this metric even listed in product reviews: it’s already been found that in 3D VR simulators this delay often causes nausea in human subject research volunteers (and thus, limits/ affects experimental designs). Similarly, in pragmatic field use, one classical photography principle is to put the sun at your back ... but this means that the sun is now positioned so that it will illuminate your LCD display & degrade its readability unless it’s shaded - such as being designed with the same eyepiece cup as classical SLR’s. FYI, shooting during Golden Hours results in a much lower sun angle which can accentuate this as a problem...the outcome is that the photographer needs to have a big fat head to make shade to see what he’s framing. -hh |

The Panasonic G1 was launched in 2007. Nikon and Canon let others do the ground-work. Sony released the F707 in April 2000. That was a mirrorless through the lense view camera. -- Regards, Eric Stevens |

Before that Nikon had their pathetic *1* cameras which were MILC. -- Regards, Savageduck |

What are you trying to say? We are not discussing 3D VR simulators. Have you tried one of the latest MILCs such as the X-T2, X-H1, or the Sony a7III? ...and then there are the latest releases such as the X-T3 where there is no blackout even at 30fps. Similarly, in pragmatic field use, one classical photography principle is to put the sun at your back ... but this means that the sun is now positioned so that it will illuminate your LCD display & degrade its readability unless it’s shaded - such as being designed with the same eyepiece cup as classical SLR’s. FYI, shooting during Golden Hours results in a much lower sun angle which can accentuate this as a problem...the outcome is that the photographer needs to have a big fat head to make shade to see what he’s framing. You do understand that MILCs have an EVF which is used in much the same way the traditional OVF is used on a DSLR. Try one some time you might be surprised. -- Regards, Savageduck |

See http://www.letsgodigital.org/images/..._F707_back.jpg See that funny thing at the top-left of the back of the camera? It's an eye-piece. -- Regards, Eric Stevens |
