I have seen exposure hunting with the V1073 when I zoom (so I try not to zoom in the middle of a key clip) but not when panning. There is a little white-balance hunting when you get right down to the noise level (panning inside a wardrobe, for example). But panning around a room, going past windows, televisions and bookcases works fine with my V1073. I haven't seen any problems out 'in the field' either.

I have bought a V1253 and when it arrives I will compare the two. Note that there is a firmware upgrade available from Kodak for the V1253 now.

Here is an example of what I mean.
Short video: http://vimeo.com/1043688
2 clicks-flashes in a 6 sec. video.
Second one - frames 138, 139, 140, 141:






Trevmar, could you please try a similar experiment - movie mode, indoor, sunny day, panning (even don't need to record). Listen and see on the screen, watch for simultaneous clicks and flashes. Thanks!

I will do this later in the afternoon, when the sun is directly on the windows

drd403, can you please unprotect the video at http://vimeo.com/1043688 so that I can take a look at it?

drd403,
I was able to replicate this effect only when I opened one window to a slit of direct sunlight.

I have noticed before that the v1073 over-exposes on white surfaces in direct Californian sunlight, which is fixed using an ND4 filter. I just tried a filter, and there is no click/flash with an ND4 or even an ND2 filter. This does seem to be a camera bug. A designer messed up It may be related to the purple lines streaking.

MODERATORS: Is it possible to get Steve's help approaching Kodak to look at this issue? And the 29 /80 minute issue?

Trevmar, thanks, now I'm sure thisis the camera bug. Moreover, looks like this is the Kodak-wide bug. I saw the same when I've tried Z1085, as well as in somebody's Z1085 samples from dpreview forum.
In minutes I'll upload the defective frames from one of this samples.

Z1085 'over-exposure' bug.

http://forums.dpreview.com/forums/re...ssage=27683111
Sample indoor, frames 829, 830, 831. Middle frame 830 is much brighter than neighbours. Very visible 'flash' in the video:

I had suspected it was a lens or sensor artifact. Is it only in the 1/1.63 10Megapixel CCD? I guess it is always possible that sensor is too sensitive for the aperture/shutter control. I am expecting a V1253 to arrive in a day or two, and will see if that has the same problem. Useful to know it is in the Z1085. No point in changing to the x5 lens system, apparently
