Nikon have released a new “serious” compact camera, the Coolpix P6000. This camera – at least on paper – competes directly with the Canon G9. This seems like excellent news.

But then I read this:

COOLPIX Picture Control NRW (RAW) files can only be processed in-camera. NRW (RAW) files are compatible for use in-camera, with ViewNX (Windows version only) or with WIC based applications. Capture NX, Capture NX2 and NEF files are not compatible with NRW (RAW) images.

WIC is Windows Imaging Component, a Microsoft API for Microsoft Windows. In other words: converting RAW files to something else can happen only in camera or on MS Windows.

So what does that mean? Not only does Nikon introduce yet another completely useless RAW format (how hard is it to realize that DNG is the present wave and certainly the future?) they clearly think that Mac users are not to be customers of their fine camera.

It strikes me that Nikon seem to be unable to understand a fundamental fact: as a photographer I want full control over my image files. That is one reason I shoot RAW. I do not want encrypted data in the file. I do not want strange and proprietary formats that reduce my software choices and leave me high and dry in a few years when the special software no longer runs on whatever computer I will have.

I do want an open, fully documented format – such as DNG. Simple as that.

So Nikon, you are quite welcome to spend lots of money on advertising this wonderful new camera, but I will not buy it. Too bad, it seems like a really nice camera that would be very tempting otherwise.

Update: At least Adobe know their stuff and Adobe Camera Raw can now read the raw files from the P6000. Nikon still don’t seem to get it … read the review by Thom Hogan for the entire depressing story.

My sensor measurement series (G9 and 5D) continues. This time, I measured a Konica-Minolta DiMAGE A2, a 8MP camera which was introduced in 2004. How does it compare to a modern 12MP Canon G9?

ISO 64 / 80 Konica-Minolta DiMAGE A2 ISO 64 f3.5 1/50 Canon G9 ISO 80 f3.2 1/60s
ISO 100 Konica-Minolta DiMAGE A2 ISO 100 f3.2 1/60 Canon G9 ISO 100 f3.2 1/80s
ISO 200 Konica-Minolta DiMAGE A2 ISO 200 f3.5 1/100 Canon G9 ISO 200 f3.2 1/160s
ISO 400 Konica-Minolta DiMAGE A2 ISO 400 f4.5 1/125 Canon G9 ISO 400 f4.5 1/160s
ISO 800 Konica-Minolta DiMAGE A2 ISO 800 f6.3 1/125 Canon G9 ISO 800 f6.3 1/160s
ISO 1600 N/A Canon G9 ISO 1600 f8 1/200s

Up to ISO 100 there is little difference between the cameras. At ISO 200 and above the 12MP sensor of the G9 shows more noise than the 3 year older 8MP sensor of the A2.

According to dpreview.com the DiMAGE A2 has a 2/3″ (8.80 x 6.60 mm) sensor. The G9 sensor is a 1/1.7″ (7.60 x 5.60 mm) unit. In other words: the pixel pitch is much smaller on the G9. Noise seems to be inversely proportional to the pixel pitch, so it is not surprising that the G9 does worse than the A2.

What happens when the images are run through Noise Ninja?

ISO 1600 N/A Canon G9 ISO 1600 f8 1/200s

Up to ISO 200, there is little difference between the cleaned up images. At ISO 400 there is slightly more noise in the G9 image, but the difference is very slight. At ISO 800 the A2 image seems definitely cleaner than the G9 image.

I am surprised that in three years there is no improvement in sensor noise. Well, there might have been if you where to create a 2/3″ 8MP sensor with todays technology, but unfortunately there is no such product.

I recently decided that a new tool would be nice and that I needed a fairly compact camera that performs well under low light conditions. Both the Canon G9 and the Panasonic DMC-FZ18 seemed interesting from their specs. [I also looked at FujiFilms offering because in the past they performed very well at high ISO. Unfortunately, a camera with the SuperCCD and image stabilization is currently missing from their model lineup.]
Trawling the net for hard information on sensor noise for these fairly new cameras proved to be a frustrating experience. There seems to be very little information available that allows a good comparison of various cameras. Yes, I know there are many snapshots available, but the conditions under which they are taken varies greatly.
The big review sites (I personally prefer dpreview.com) are somewhat better, but none had a review of both cameras online. In fact, dpreview had published a review on neither camera.
So I decided to create my own test setup to determine how the cameras that I have access to perform and to allow a comparison. Because I just got it, I started with the Canon G9.
