Sure ... but that underscores that you have not really analyzed what you want in a camera. It's basically a toy ... what feature set will interest me today?
Exactly, it is a toy. I make no money from photography, and I post most of my pictures under the CC license. It's a hobby.
You haven't seen the IQ. I am not sure how many times I need to say it, but until wee see what the cam does in DR mode, there is nothing useful to judge by.
That Japanese site had DR, SR and HR shots of the same scene.
I have no argument there. If the DP1 matches your needs, then the feature set of the F300 was overkill by a long way ...
Most of my shots are landscapes and macro. Both cameras suck at macro (and I have a DSLR with a nice macro lens for that anyway). At landscapes, the Sigma is clearly superior, except for the lack of 24mm (but compensates through noise, color and resolution). I shoot tele pretty rarely, maybe 5% of my shots. Probably less than 1% of my shots are at any FL except for full wide or full tele. If I went for the F300EXR, I'd get no useful macro, decent landscapes, decent telephoto.
However, with the DP1s I get excellent landscapes, no macro and no telephoto.
So for me, both choices were compromises. But I feel I compromise less with the Dp1s.
Besides, the DP1s will still be a great camera even in a few years, while the F300EXR will probably be made obsolete by other models in a year or two.
I am not sure how exactly they measure the DR, but the fact is that overall, the DP1s gives better results in harsh light than the F300EXR (or even than the F200EXR) if you play a bit with the RAW mode.
That statement has no basis in any reality. No head to head tests have been done to my knowledge.
Look on Flickr for Dp1s samples. You will see some high contrast scenes where everything is exposed nicely, and there is no shadow noise. I am talking abut normal high contrast scenes such as landscapes in the evening or at noon, not special occasions, like tunnels.
The way every review I have yet seen of an EXR camera has been shot. Once one has seen a comparison of HR mode against DR mode, HR mode is a waste of time. From what I have seen, most of the sites have shot HR mode almost exclusively.
And that's how you shoot these cams wrong.
Look again at that Japanese site.
The recent Japanese site was a terrible review.
Why? Because the images took a while to load it means the review is bad?
Now, if fighting with the sensor for low light shooting is your cup of tea, enjoy the cam. But despite the APS-C sensor, that is no low light cam.
Obviously. No F4 camera is a low light camera. And there is no IS.
Nevertheless, I think it will do better than other compacts in low light.
I think I could compete with the Sigmas in low light ... fighting the color and tone shifts alone will keep someone quite busy ...
At least you can convert it to a monochrome picture. But fighting very aggressive NR will be even harder, if not impossible. Keep in mind that unlike a Bayer sensor, a noisy pixel will only affect that pixel, not all the nearby pixels
But is has the same features as the F300EXR ... to get the size, they tossed all the features.
Obviously, some compromises must be made. You can't have a perfect camera.
You keep saying that ... but you are wrong. Obviously, you can always dial up the exposure in RAW converters, but all you are doing is applying a digital amplification (we sometimes call that multiplication

) ... that is rarely as good as the analog amplification in the sensor ...
If the sensor A/D converter does a good job, the results are going to be very similar. You still have the same number of photons hitting those pixels.
I hope you manage to control some variables ... the last thing we need is yet another kangaroo court in this forum ...
I am sure we can manage something.
My comment was on the DP2 ... that cam remains about triple the price of the F300 (despite raist3d's insistence otherwise) ...
Yes, the DP2 is at a different price, but I was talking about the DP1s. Not that it changes things, since most things are the same, except for the FL.
Um ... the differences are a little stronger than that ... more like dog vs cat with 1 leg missing ...
For my needs, the difference is pretty small in terms of compromises for both cameras.
