Here is crops in low light(indoor):

left is Panasonic,right is Sony

In low light Sony is producing visible more dinamic range.

Also in this conditions Panasonic(50ISO) is 2 times less sensitive than Sony(100ISO)

1. Wide:

Panasonic A-2.8 / S - 1/15

Sony A-2.8 / S - 1/30

2. Tele (190mm):

Panasonic A-2.8 / S - 1/30

Sony A-2.8 / S - 1/60

Thanks for letting us know. That's would I would have expected to see. If the Panasonic was more sensitive at ISO 50, then I think that they would have marketed it as starting at ISO 100 (to make it look like it was capable of higher ISO speeds). As far as dynamic range, that's to be expected, too. The Sony's larger and less dense sensor uses larger photosites for each pixel.

About ISO - in good light ,I check now ,both cameras is producing same results !!!!

In low light - different !

Why then Canon G3/G5 is much more sensitive in 50ISO than other cameras?

You can check all Fill Askey reviews andcomparisons for this matter.

In low light conditions,Sony is better,but ,have in mind that not enough ))

Right decision in low light is DSRL.

Which one of these cameras would make a better choice for photographing children?

Yes, I am familiar with the Canon's behavior.They test about 3/4 stop more sensitive than their rated ISO speed. So, they are an exception. However, the newer G5 still has higher noise levels than competing models when you increase ISO speeds (even when adjusting for it's ISO speed sensitivity differences), according to Phil's tests.

Phil is in the process of reviewing the DMC-FZ10 now. So, once his review is finished and published, that should let us know how noise levels compare from it in controlled conditions testing.

Of course a DSLR is a far better choice in lower light. However, to get DSLR + a bright lens atlonger focal lengths (i.e., the Sonys 190mm Equivalent) they get quite expensive. So, some users try to "get by" with a model like the Sony DSC-F717 (for indoor concerts, etc.), since it's lens only stops down to f/2.4 at full zoom, and you can use Neat Image to help reduce the noise later when using higher ISO speeds, if only web size photos are needed (where image degradation tends to "blend in" more).

300D + 50/1.8 is perfect for low light fotos..
For long focal lenght + low cost I tested 300D + Pentakon 135/2.8(30usd) and Pentacon 200/4(30usd like new). They are producing very nice pictures,ofcourse if you have some experiance with MF )Good news for 300D/10D is that you can use old 42mm lens,and metering is working.
Also very nice decision for 300D are old Asahi-Takumar lens ...
