FZ20 Lens Movement
Hi,
Just been playing with my new FZ20 and noticed that there is a noticeable radial lens movement - laterally and vertically (in fact in all directions) when the lens is extended after switching on. This movement is in the order of 2-3mm. It is not a lens movement in or out of the camera. The entire lens, with all the lens elements, seems to move at the same time can be moved with very little force - I noticed it with the briefest of touches. Pictures appear to be OK. Is this a normal movement??? - or should I take the camera back to whence it came from??? TVMIA |

You do not get this with film SLR lens. Much more precisely built.
Almost all lens of the new cameras ,which extend from the body, do that. I think it is just free play needed to let it move. This is the price for being light and small.

I think not. The sensor size in ZLR cameras is a lot smaller and the tolerances consequently smaller, probably calling for greater absolute precision during manufacture. Cheers, David |

I think not. There are film ZLRs such as the olympus IS-3 that have such a lens that extends (although not all the way) at power on. However, the lens was designed to support teleconverters (such as the tcon 1.7x) and is much more stable. |

They are somewhat battered and scratched but in good working order. It is clear that none of my digital cameras will ever reach this condition. Why is this? Building a camera to use digital capture does not mean that it has be to fragile. Robert R. |
