  • was this recorded at night? does it do night vision too?

  • @0575anna Recorded in the evening on an overcast day. No, it doesn't do night vision.

  • does telephoto lens make youre camera zoom faster?

  • It doesn't affect the mechanics of the camera, as far as the zoom drive motor.

    However, you can zoom almost 2x "faster".

    The stock lense zooms from 1x to 10x. With the teleconvertor it becomes 2x to 20x across the same zoom range. So technically speaking, zooming from 2x to 10x is faster with the telephoto converter because it is going from 1% to 50% of the zoom, whereas the stock lense is going from 20% to 100%, which takes longer.

    Don't know if that was what you were asking or not.

  • As a very late followup, the 1.6 lense gives us an operational range of about 60-99 on the zoom scale without vignetting. That gives us the zoom range we need (about 9.6x to 16x). It would be nice if the camera's computer had a zoom range lock, so we could restrict zooming to the effective range. Currently the camera operators have to watch the zoom value to make sure they don't cause vignetting by zooming out too far.

  • i'm considering buying a cheap teleconverter for a Sony HDRFX1 and am wondering what zoom-through is and what types of quality issues I might have using a cheap teleconverter instead of an expensive one like you used.

  • thanks

  • We ordered through Full Compass. It was around $1350. It doesn't have as much zoom-through as we had anticipated, so Schneider is exchanging our 2x lenses for 1.6, which should allow at least 50% zoom-through.

  • Wow what a difference! How much was the adapter & whered you buy it? Too bad panny didnt make the dvx with a 20x zoom eh.
