The Panasonic LX2 was introduced in 2006 as the follow-up to the LX1.
See this link for a review of the camera:
Panasonic continues the same line of cameras: LX3, LX5 & LX7 in 2008, 2010 & 2012.
There has been minor additions with each camera but the camera remains about the same.
All are 10 megapixel, which is good. That is the sweet spot in Megapixels for picture quality.
The lens has gone to a wider angle but maintains about the same zoom levels as yours.
In the LX7, they changed to the CMOS sensors which are faster than the older CCD sensors.
The picture quality has been excellent from the LX2 through LX7.
Video improves each year.
I love this little camera. Where is the best place for me to ask questions about this camera?
