Mine is a class 2 memory card, I don't understand the classes of memory cards and how it affects photos. Could you explain the difference? I assume the higher the class the better, I'm new to all this, the TZ10 is my first camera, despite using the Canon G10 this is the first camera I have ever actually owned!
I have very impressed with the quality of the HD video! Of course it can't compare to full HD but i really do enjoy using it. Would the quality of HD video increase if I had a higher class of memory card?
I would recommend you to buy a SD card reader, I am about to buy one (along with a gorillapod!) for my TZ10 because my desktop computer doesn't have an SD card slot.
I really think the stabilization is brilliant, especially with zoom you notice how good it is. By the way, there are also some tricks to get extra zoom...
I haven't noticed the huge file sizes with 12 MP, but that would please me because it means the photos aren't being compressed.
I will always prefer to use the 12 MP resolution setting as I am always zooming in on the photos to inspect the detail, and if i want to crop a 12 MP image then enlarge it, it will look better than a 5 or 3 MP picture cropped then enlarged
