I'm hoping that as you're someone who genuinely has used the TZ20 and now owns a TZ30 you can offer correct comparison info as I've found reviews often miss out details eg the USB connector style changes from the TZ10 to TZ20, but no 'official' reviews mention it !
I had a TZ10 and upgraded to the TZ20 recently.
The big feature I use a lot is 'Panorama Assist'.
On the TZ30 it's now a sweep method as opposed to the previous take-photos-manual-one-by-one-then-stitch
Have you used that feature on the 20 and then the 30 much to compare the practicalities of each please ?
I'm not bothered about the new ability to see the panorama stitched together on-camera, but I've seen a demo video of it in action and what I can't quantify is how easy it is to lose the subject in vertical framing - something you can ensure remains constant with the picture-one-by-one method....
Also, does the 30 still have the 1s-or-so 'blank screen' after pressing the video record button (an annoying 'feature' which both the 10 and 20 have !) before it shows what the lens sees again or does the display constantly show the lens view (ie like my Panasonic camcorder does).
I often find that dwell time means I've moved the lens view during it and the subject is not in frame any longer - especially pertinent when zoomed-in.
[I hope I've explained these 2 very specific aspects well enough for you to understand them !]
As an aside, I'm disappointed that Pana are moving their photo products to charge-in-the-device when previously it's via an external charger. Have you had any problem getting /considered an external charger or spare battery please ?
Thanks in advance for any info/opinions.
