Can I manually control the zoom and focus? - JVC Cybercam GR-D200US Mini DV Digital Camcorder

If this has a motorized zoom and focus then it will be on the remote listed as zoom and focus or on the hard buttons on the projector itself. If you don't have this feature then you must focus and zoom manually on the lens itself. There will be two tabs or rollers that you make these adjustments with this.

Could be, because most camera's only can auto focus till f/1:5.6. And if 5.6 is reached at the focal length of 200 mm, the camera stops it from going to a part it can't be focused.
Perhaps you try the lens in manual focus, and manual zoom.

Zoomed fully in, the minimum focus is about 20 inches. If you want to focus closer, you must zoom out. See page 72 of this manual.

i was not able to find a manual - this review may help http://www.kenrockwell.com/nikon/3570.htm
The lens consists of

1. Zoom
2. Focus
3. Aperture
4. Macro

1) Zoom - this is by push pull - so you push the lens out to wide angle 2) To switch to manual focus - will need to be done on the camera and then you can use the front control ring to focus - 4) also you can use the button to switch to macro mode - BUT only with the Zoom at 35mm - lens fully extended 3) You have an aperture range of 2.8 - 22 this varies the amount of light allowed into the lens - 2.8 is the most light - F4 to F5.6 to F8 - each change halfs the light allowed in - so changing from F4 to F5.6 half the light

Yes. It's a push pull zoom action.

One touch zooms as used on 35mm film SLRs used to have the same mechanism, the zoom ring twisted as well to achieve focus but now that most lenses are autofocus that's unnecessary. So you have a lens which just retains the push-pull, a far more natural action in my opinion and usually faster than a rotating zoom. Once you get used to it I think that you'll prefer it.

By contrast, most modern zooms have what was considered in 35mm terms to be an old-fashioned twin touch zoom: one ring was turned to zoom the lens and another was turned to focus it. This sometimes meant that after zooming you had to refocus; your push pull zoom will likely have a more technically demanding constant focus zoom action, there will be an additional manual focus control as well, but it's very much a minor secondary control used only when your AF has broken or is switched off.

I hope that my reply has been of use to you, please return the favour by rating my answer.

It sounds like the optics in the lens are no longer calibrated. It needs to be looked at by a professional.

Tom, It's best to do the zoom first, then focus (if you are using the autofocus).
