The FZ-1 has a 1/3.2" sensor as compared to the 1/1.8" sensor in
the G3/6. That is a 5mm diagonal vs. a 9mm diagonal or almost two
whole stops of sensor area disadvantage. It is also a Panasonic
CCD and they have fairly consistently underperformed similarly
specified Sony sensors. Granted, it is only a 2Mp sensor so the
pixel pitch isn't horrible. But it is also a sensor that is quite
old (around 2002). So it is no wonder that the E-500 trounces it.
The G3/6 would also.
Well, considering the G3 is a 4mp camera and the G6 is a 7mp camera, I would expect the sensor to be bigger than a 2mp camera. That being said, I'm confused by your criticism of the age of the Panasonic sensor. The FZ1 was announced in September 2002, but was not available in the USA until like March 2003. The G3 was announced in the same year (2002), so since I doubt they could look ahead and put 2003 sensors in a 2002 G3, I'm just guessing that the sensors are roughly the same "age".
The G3 does have much more impressive features than the FZ1, but one cannot argue that the FZ1 has a much better lens with a lot more reach that's faster at f2.8 at the max zoom of the G3, and continues at f2.8 throught the 420mm equiv. range I mean, we are talking about using P&S cameras from the bleachers in a dimly lit gym for action shots. 140mm equiv max zoom isn't going to cut it, especially not a f3.0 with a max ISO of 400. You can put a T-con on it all you want, but it will further slow down the lens and then you also face blur from camera shake above and beyond the motion blur that you're going to get at the shutter speed required for that low of ISO and that slow of a lens combo. Speed up the shutter and your still limited to ISO 400 so your photos are going to be dark. The G3 was also reviewed as having "noise worse than the competition" at ISO 100 (yes, that's ISO 100), so that doesn't sound like a very good low light performer to me. With a firmware upgrade, the FZ1 added aperture and shutter priority modes, as well as eliminated the darkened EVF syndrome that original afflicted it when shooting in dim light. The firmware also lessened the compression significantly to reduce similar "jaggies" that the G3 was criticized for (and not corrected).
So, before this gets off-topic any further into a G3 versus FZ1 debate, my point is that the FZ1 is a very difficult P&S camera to beat, primarily because of the lens -- the reach and the speed. It definitely blows the doors off of the modern day "pocket cameras" with the 25" LCDs (sarcastically speaking), no viewfinder, and whopping 3x optical zoom. Those aren't cameras that are going to cut it at sporting events, just like the meager reach of a 140mm equiv of the G3 isn't going to cut it either.
....and this is why people who would normally get P&S cameras are turning to dSLR, because the P&S cameras simply can't cut it at these types of events. They're great for bright light landscapes, useful at parties for their compact size, etc. I'm not saying that they're without purpose, but they have little to know purpose at an indoor sporting event.
