Microphotography
I am looking for a DSLR which has a mirror lock up. I want to reduce
vibration when using the body with a microscope or telescope. For the same reason, the metering must be shutter priority and this must function with only a T2 mount in place to connect the microscope / telescope to the body. Any suggestions please? Robert |

o.uk... I am looking for a DSLR which has a mirror lock up. I want to reduce vibration when using the body with a microscope or telescope. For the same reason, the metering must be shutter priority and this must function with only a T2 mount in place to connect the microscope / telescope to the body. Any suggestions please? With shutter-priority, you're asking the camera to adjust the lens aperture to get the right exposure. But you have no aperture connected to the camera directly or indirectly to be adjusted. Perhaps you mean aperture-priority where the camera assumes that the lens is already set and it chooses the correct shutter speed? Norm |

Robert The 20D has a neat mirror lock up feature where if you use it with the timer it will lock the mirror up on the shutter push wait 3 seconds and then take the photo. If you don't use the timer it will lock the mirror on on the first push and the take the photo on the second push. Scott |

I just bought a Nikon D200 which meters excellently with all sorts of weird manual lenses, bellows, etc. I am using some extreme Olympus micro lenses with RMS mounts on bellows, which is basically the same as microphotography, and it works great--plus mirror lockup. For telescopes, however, you probably want excellent high ISO performance--go with the full frame Canon 5D for that (but it is expensive). Toby |

I just bought a Nikon D200 which meters excellently with all sorts of weird manual lenses, bellows, etc. Glad to know Nikon have improved this - what I said yesterday related to the D100/D70 series, which my Nikon-using friend had problems with.

Also, be aware that some DSLRs are less happy to meter without a "proper" lens in place. My EOS 10D does just fine, as do other EOS models, but I know others who use Nikons and they say it is less satisfactory - there is a workaround, but it's more fiddly. I don't believe that's the case with any Nikon DSLRs that have mirror lockup, or with the new D200. -- Regards, Matt Clara www.mattclara.com |

You're restricted to using M-mode with these cameras. The D200 finally removed this restriction. "Pro" Film bodies like the N90, F100, F5 & F6 also allow A-mode metering with any lens but the Mass-Market cameras like the N75 and it's cousins are as incapable as the D50/D70 in this regard. Norm |
