elgerber: We LOVE this camera (Panasonic FZ10k). It's amazing. I don't know what the FZ20 will be like, but I wanted to "play" with it quite a bit before our vacation and wanted it NOW. I'm not sure how much you know about the FZ10, but here's what I like...
It has a 12x zoom (plus a 3x digital for a max of 36x). I'm not into the digital zoom, but it has it. You can review pictures one by one or look at 9 at a time. You can record movies (around 30 minutes on a 256 panasonic SD card). It has this cool "flip animation" feature where you take single pictures of an object (up to 100 pics) and then play them back like a "flip book". It's sort of a fun game type thing, doubt if I really use it other than to play with. You can record pictures with 10 seconds of sound - very cool. Don't know what I'll really use that for, but it's fun to play with (just like the movies - don't know that I'll ever use it, but it's fun)
The pictures are GREAT. It has an image stabilization that is NECESSARY with the high zoom and it works well.
It takes pictures extremely fast - seems to me it might be faster than my 35 mm!!! It has a "burst mode" that takes several pictures in a row (choice between 5 fps or 2 fps, I think). That will come in handy and help me prevent the "just missed the shot" situations.
Also, highly recommend the panasonic SD cards - VERY fast write speed - 10 mb/sec. Some off brands are as low at 2 mb/sec. BIG difference.
This is a 4 mp camera with a 12x zoom and I LOVE IT!!!! (can you tell?)
Here's a tip... I ended up buying off of B&H Photo. They had the panasonic card, xtra panasonic battery (don't know if we'll need it, but I wanted the piece of mind of having extra in the bag at wDW), and the camera for a good price ($499). To get the $499 price, you have to add the camera to the "shopping cart", but you can always decide not to "check out". I was between this place and buydig.com, but B&H had everything I wanted. The camera arrived in a never opened box, in perfect shape and VERY quickly. They sent confirmation emails with tracking numbers and there's a phone number to speak to them if needed.
The only negative thing I could possibly say about this camera is the size, but what can we expect from a camera with a 12x zoom and a great lens. Honestly, it does everything that I used my 35mm (with zoom) for and I will probably never use my 35mm again. Oh, one more "negative", the lens cap is not attached by a string, so they tell you a zillion times in the manual - don't lose lens cap!!! (but it's only $7 to replace) I plan on getting a stick on lens cap string from our local camera store (also need to find a good camera bag for it).
If you have any specific questions, you can post again or PM me.
