Co-linear dual tripod mount for huge lenses I hear you, and that was the answer given in the other question, but the difference seems to me to be an important one: I'm not connecting the camera to the lens. I'm connecting lens -> T-ring -> teleconverter -> FT-1 adapter -> camera. That many components meaningfully lengthens the apparatus and alters the profile of the forces significantly, where the weight-bearing design considerations of each element are questionable to begin with. |

Co-linear dual tripod mount for huge lenses Oh good, so only 6x overpriced. Thanks, that diagram is exactly what I want. Not too keen on setting up a metalworking shop though... |

Is higher ISO noise evenly distributed, or does it affect colors differently? Andrew, I'm going to go out on a limb here, but I think the ISO ratings do indeed work that way: since each doubling of ISO doubles the sensitivity of the "film", an ISO of 3200 has been doubled 5x from 100, so the noise has also doubled 5x over, from (let's say) 1000:1 to 1000:32. Noise, blurriness, or darkness: pick 1! |

Why do the Nikon V1 lens' websites seem to give different f-stops than the lenses? Yes, thank you. Of course "aperture" is way beyond the scope of any question :) - I didn't consider that it could be controlled independently of zoom and the fixed glass of the lens; I now realize there is an iris within the lens to adjust the actual aperture diameter. |

Why do the Nikon V1 lens' websites seem to give different f-stops than the lenses? When is the minimum aperture used, if the maximum is used at all levels of zoom? |
