Since you're with the company, please think about plugging in a universal card reader through the USB port to load images from CF, memory stick, etc. Then you'll get my business.

If you look at the sample photos on their website, there seems to be a lot of noise in the shadows of the night shots. Buyer beware.

This kind of image compression becomes especially nasty with filters such as Smart Sharpen in Photoshop, which need smooth, accurate image data to work at their best. Good that Sony woke up.

There is some weird moire or diffraction effect on the bottom left light, out of focus in the background. Also the gray roof or window beam just above the light has a pattern of some sort in it, which doesn't look like it's some kind of artifact. Something from the fresnel element? Hard to say.

Send me a Jpeg, I'll manipulate it and send it back to you. Jpeg format can be manipulated without detection as well. It's just a matter of how careful and knowledgeable one is.

Nikon has always done specialty instruments, mostly outside of the camera market. While this camera isn't for me, I can't wait to see the pictures it takes. I'm still waiting for a 5x macro lens. Maybe someday.

Also, I agree with many other posters that it's long past the time to stop putting down photographers simply because there is some fault with their work in the eye of the viewer. We don't need a love fest for everyone Dpreview selects, but piling on to criticize is unprofessional. If one wants to be a critic, join a critique group. Criticism is best done when there can be a relationship and a dialogue between photographers. I've learned much more from belonging to a critique group than I ever did from random comments received online.

The caption for photo #1 appears to be incorrect. The virga shot is later in the slideshow. Nice photos; I've been to some of the locations but not had the time to get the results he's accomplished.

I especially like the way the trees on the left appear in the water, but not in the sky. Nice job with the healing brush and clone stamp! A perfect homage to Lik and well-deserved first place.

"Kakadu" is a C++ closed-source implementation of Jpeg-2000 from Kakadu Software (kakadusoftware.com). I'm not an expert on it, this is the people who wrote it. It seems that the major benefit of BPG is sharper, smoother edge detail at the expense of preserving texture. You get one thing at the expense of another, as is always the case with compression.

Jpeg 2000 is there; it's listed in the dropdown as JP2K-Kakadu.

I took some test shots of this lens down at my local photo store. I was disappointed at the sharpness. It would be fine for web resolution, but not for any kind of print at 8x10 or larger. It also has a plastic bayonet mount. Yes it's cheap, but I was hoping for better quality and would have paid more for good optics and a metal mount. I didn't buy it, hoping for a version 2.

While the DR test does look nice for the Panasonic, look at the other parts of the photo and the G7X really shines (as does the RX100 III.) I'm not sure I'd want to pay the extra for the Panasonic and sacrifice a longer lens and superior resolution of the Canon or the quality of the Sony. The Sony lens looks deliciously sharp compared to the others.

I see it in Raw conversions using Capture NX 2. There's a D800 ad shown in print magazines of a woman standing in a forest with a dress that has a forest print on it. Interestingly, this image has exactly the same issue. All the greens look the same, when there ought to be a lot more hue variation.

I'd like to see some sample images emphasizing green foliage. I've found the D800 to be weak in hue separation of greens, and it would be a help to see how the D750 compares.

It may be the G7X wasn't aligned parallel to the test scene. Look at the color wheel on the lower left vs. the upper right for the G7X. The upper right is much crisper, and actually a bit better than the RX100 in that part of the image. On the lower left, the two are reversed with the RX100 looking better. Both cameras ought to be re-shot with the lens wide open to check alignment before doing the final test image.

Thanks, this explanation really helps. My next question would be, what is the exposure latitude like for that top layer since it receives all wavelengths together rather than just red, green, or blue? It will be interesting to see how the sensor stacks up in that department. Since there's no blue color filter, I also wonder how it deals with yellow since a bright yellow will register high intensity on the top layer as well as the red and green layers, making it difficult to distinguish from white light. I've seen some Foveon tests on color separation, but never seen a white/yellow pattern. Maybe there's a reason for that, because it shows the problem. Admittedly, white/yellow distinction is a fairly rare situation photographically.
