I don't know if they are acceptable or not because your samples are tiny. Even at that size, your first hummingbird photo is loaded with noise at the low ISO of 400. That's a problem with small sensors. I suspect the FZ1000 will give better results at 400mm than this camera at 600mm because it's possible to crop more and the sensor has a lot more resolution (20mp vs 12). Another thing to consider is Sony cameras have AF superior to Panasonic.
Hi Tom,
I realize small sensor cameras generate more noise, all other things being similar, than larger sensor cameras, and different people view photos differently.
However, the second hummingbird photo, while I'm sure has similar noise to the first one, was recently chosen as image of the day on imaging-resource.com, and has come in the top ten twice here on bird photo challenges, where darn near every other submittal is a ILC crop sensor/ff camera able to produce images with far less noise. My point, to many photographers/viewers, the composition and subject is far, far more relevant than the noise in an image.
I personally view many images on this DPreview.com, recently quite a few on the Nikon Z board shot with $5K Z9s and multi thousands of dollars lenses that I find not nearly as good (subjective, of course) as images shot with small sensor cameras with far more noise. And as we know, if one really cares about noise these days (I don't much at all), just use a good PP noise reduction software and the final image will have far less noise.
Composition and subject is what is important to me, not the amount of noise, which is close to irrelevant, as far as I'm concerned.
Also, if you went to the links I posted showing images shot by a serious amateur photographer using the FZ300 and some PP, I think you'll agree that the camera can hold its own in many situation against 1" sensor cameras, unless one cares more about pixel peeping than the actual photograph.
Best,
TFP
