Default Why are non-SRL zooms motorized?

As I said before, I'd love to be able to go back to non-jerky, endlessly more fast and exact framing manual zooms.( Non SLRs)
Are others of the same view?
Why is industry not at least allowing the option?

not sure I understand the question. If you're saying manual focus is faster than autofocus I would say you're not using a good quality lens. Today's AF technology with a good lens that has a quality focus motor is infinitely faster than manual focus. But, not all cameras and not all lenses are created equal in that regard. In poor light, consumer grade lenses will have issues.

I believe he is talking about being able to change the focal length of the lens manually, as most SLR zoom lenses do, and as I can do with my Minolta Dimage 7hi. Having used the motorized zooms, I completely agree that manual is much better.

The funny thing is that one of my very first posts here was to ask for a non-dSLR camera that had a mechanical zoom - I wanted to be able to adjust the zoom as I wanted, rather than having to try to hit the right point with a motorized zoom. The old FZ30 was one camera that had a mechanical zoom. So I can also relate to this topic (though I ended up moving to a dSLR after I didn't get along with the Panny).

There are only three others that I'm aware of that do that and one is no longer being made: The Olympus SP-570UZ, the Fujifilm HS-10, and the Fujifilm HS-20EXR. I could be wrong but as I said... "that I'm aware of".

G'day TP

I think your comment regarding zooms relates to the 99% of P&S cameras where the user pushes the zoom button left or right to zoom in or out ... rather than the SLR lenses where the user rotates by hand the zoom controls

In answer, I would think of 2 things here - a) most P&S cameras have small lenses (in size & weight) and as such a small motor can do the moving, and b) most users of P&S cameras are not serious photographers (like we are) and do not mind if the image is a fraction 'out' ... too big or too small, as they can adjust it during printing if they desire

The small number of non-SLR cameras that do have a manual zoom ring [ie- as listed above by gjt] are the exception, and no doubt the owners of those cameras are serious photographers who like the type of camera without the inconvenience of the SLRs size & weight

Hope this helps a bit
Regards, Phil

I think the reason for this is that entry level SLRs are at a price level to compete with the more advance fixed lens cameras, and more serious photographers opt for the SLR, leaving very little market share for advanced P&S cameras.
Probably the peak of development of the manual zoom fixed lens camera was the Sony R1, with APS-c sensor. This was a manual zoom, as I recall. Would have gotten one at a somewhat lower price.

You are right, I was referring to faster and more exact Framing, not focussing, i.e. manual zooming. Do you think there is a technical reason not to give the option of manual zooming? Because I believe that the vast majority of consumers are getting unnerved by the inability to do any excat framing with a motorized zoom, jerking backwards and forwards until the shot is lost.
In short, do you think camera industry is misreading the consumer in this respect?
