The manual suggests that you can take a RAW image on the card and use it as the starting point for a multiple exposure when using the 'overlay' setting, but I just get a 'Cannot merge using this photo' message. If you start a multi exp with overlay off and exit after the first shot, then this image can be used with the overlay setting, but will not write to the card at the end of the sequence, requiring the camera to be turned off and on again to clear.

I thought this worked okay when I first tried it, but I've had no joy since. Anyone else experienced this problem?

I don't actually want to create a multi exp, I simply want to use the overlay to align individual shots to create tracking movements of larger objects like buildings. This is where I think Panasonic missed an opportunity, with what would make a useful creative feature.

If there was an onion skinning preview that just engaged an overlay with the previously taken shot, it would open up some really interesting opportunities.

"Our system can be used with commercially available DSLR cameras and photographic lenses without modification to either. We leverage the fact that defocus blur is a function of scene depth and f/# to estimate a depth map. We demonstrate several applications of our multi-aperture camera, such as post-exposure editing of the depth of field, including extrapolation beyond the physical limits of the lens, synthetic refocusing, and depth-guided deconvolution."

Interesting tech, the lens Is CRAZY!!!
