I'm in love

As a good nerd it is a new camera from Nikon that specifications wise as close to perfect as I've ever seen.

Nikon announces new high ISO monster

The D3s. The thing is capable of ISO 102400. The Sample images show amazingly clean ISO 12800. The ISO 102400 I am sure of course is a trick mode (HI 3) that is really ISO 12800 boosted in software. Still the images very impressive as I am sure the price will be. For the rest it is like the old D3. And oh yeah, there is a movie feature which shoots in silly time-limited mjpeg, a codec from the stone age that nobody uses anymore. Why no mpeg4/H264? Now the question is with the D3s and the D3x, where is Nikon's answer to the Canon 5D mk II? The D700x?

Reviews of the new M9

Just a quick ist of reviews I saw looking into the new M9.
Luminous Landscape. He loves it.
Jonathan Slack's review (lots of great pictures)
Dpreview. They also actually touched one.
Focus Numérique. If you read french. They have some 100% blowups of high ISO images.
Ken Rockwell. He doesn't have one yet, but still waxes lyrical.

If you know of any more let me know. Concerning reviews, I just don't understand why Leica doesn't think I am worthy enough to test one ;-) . Of course, I am far from wealthy enough to be able to afford one, so I am decidedly out of the market. Still it is is nice to finally see a nicely simplistic, well designed, rangefinder camera with a full frame sensor.

EDIT: Another nice one here from David Farkas.

Leica M9

The web is abuzz with the (obviously not by accident) leaked specs for a new Leica camera called the M9. Apparently this will be a full frame rangefinder with 18 megapixels. I scoured the (adorned with very enjoyable Cuban street photography) pdf brochure and this looks likie a fantastic camera. If you're asking about the price you are decidedly not in the market for this thing. Expect it to cost as much as a D3x. Even though the brochure is clearly real, there are some strange things. This camera's native RAW format is DNG (hurrah Leica!!!) but Leica claims the format maintains the sensor's total 16 bits per channel? That makes no sense. No current photographic sensors have a 16 bit ADC and if they did, it would be utter overkill. There are simply not enough photons to make the signal-to-noise ratio low enough to warrant more than 14 or even 12 bits considering the pixel size on a 18 MP FF sensor. You're just more accurately imaging noise, which really doesn't help you with anything but create bigger files. Not even the D3 with far larger pixels needs 16 bits as 14 bits is already overkill simply because of basic physics. Anyway, the uncompressed DNG files are supposedly 36 MB, which is precisely right for a 16 bits capture on a 18 MP sensor. Concerning the DNG files, why is there no lossless compression that is standard in DNG (lossless jpeg), but only a gamma trick similar to the one Nikon uses in its lossy compressed NEFs? This seems strange to me. Lossy DNG compression is very much nonstandard and unnecessary as the lossless jpeg compression is just as efficient, but it is lossless. All in all, this is a very interesting camera, with some interesting technology. It is going to be very light and should be ideal for street photography and also landscapes. On the other hand, this thing is going to be extremely expensive. If you need the quality but cannot grok the premium price you'll pay for this Leica and don't mind a little extra volume and weight, consider a Canon 5D mk II or a Sony A850.

Images from the Canon 5D mk II

Photography blog has a review of the 5D mk II that includes RAW and jpeg samples. Check them out. As I said before, if you want image quality, especially for landscapes, this is a great camera and it is borne out by the images. You can load the RAW into Lightroom and Aperture by using Adobe's free DNG converter to convert them to CR2, or by using ACR 5.2 in PS CS4. The detail is very very good, and at least on par with the D3x sample images posted by Nikon. It remains to be seen if RAW from the D3x also results in better detail than the jpegs they posted. Of course, the D3x is going to be a better camera from everything but image quality such as build, autofocus (which is weak in the 5D) and other factors. A landscape photographer, however should care very little about those, but should care about real resolution, color rendition and weight where the 5D mk II scores very well.

The D3x is out

Long a rumor, now it's real. Nikon released the D3x, a 24 MP monster in a D3 body. There are some very nice sample images here and some other ones in a annoying and crappy flash interface here - gorgeous images though. Gorgeous detail and beautiful color. However, the price of $8k! makes it completely irrelevant for me. If you're a commercial studio photographer then of course this is great, but perhaps offers not that much different from medium format digital except for the use of all your nikon lenses. If you're a landscape photographer, you have to be super rich or super successful to afford this and then you'll still get far better quality using large format analog which will set you back far less. Or go for the Canon 5D mk II, which offers basically the same quality (for landscapes) in a much smaller package. Let's hope Nikon comes out with a D700x to compete with that using the same sensor as in the D3X. The D3x is a monster. A beautiful one, but a monster nevertheless.

Update: Ken Rockwell writes "... Nikon dared ask $8,000 for a $5,500 camera that is the same thing as the $4,200 D3.", and "The D3X is Nikon's greatest camera ever; it's just not worth $8,000, except to turkeys." He is absolutely right. Don't bite at this price. You can get the same quality using Velvia 50 in any old 35 mm Nikon you can get for $50 on craigslist if you own a good scanner or use a good scanning service.

Update II. Wonderful analysis by Thom Hogan here.

New tool for pixelpeepers

There is an interesting new website called dxomark that has a very comprehensive database of measurements on the performance of different digital cameras. This allow you to do quantitative comparisons between cameras from different manufacturers. Of course, you have to take these things with a grain of salt as invariably you'll find that the most expensive camera is by far the best in these measurements considering noise at high ISO, dynamic range and such. However, if you go out in the field and shoot an image at ISO 100 of a landscape with the camera you would not see any difference to your much cheaper one. And of course, if in such a situation you would shoot using a 4x5 camera with ISO 50 velvia or so, you would get far higher quality images than even the most expensive Canon 1Ds MkIII or Nikon D3. That said, I was curious for a while about what the actual IQ difference is between my D300 and the very yummy D700. Well, here it is. One example is the signal to noise ratio:

which is a full 4 dB better for the D700 at 200 nominal ISO, which corresponds to over a factor of 2 more noise in the D300. This certainly squares with my observation of noise at low ISOs in the D300. If on the DxOmark website, you roll your mouse over the scalebar on the right, you will see what this means for the image. Giving a very similar image to my examples.
Here is the dynamic range:

As you can see, apart from the base ISO, the dynamic range of the D700 is more than a stop better at every setting. That is impressive!

Now if any of this matters to you enough to spend thousands of bucks extra depends on your priorities. I wish I had the financial means to get a D700 and full-frame lenses but right now it is just lusting. I wish it had better resolution though, as from everything I have seen, the D700 gives exactly the same sharpness as a D300. The full-frame advantage doesn't hold up at all in that parameter. For that, use a 5D mkII, or a film camera I guess.

RAW files for the D3 and D300

Just found these examples of RAW files taken with the new D300 and D3 and compared to the D200. Lightroom and ACR will read all these files, so you can easily compare them yourself. The white balance is wrong in the file, so use the eyedropper on the grey patches in the colorchecker to get good color. Shortly, the high ISO performance of the D3 is absolutely crazy. It is also amazingly sharp. At 1600 ISO, compare it to the D200 file. The D3 has gobs and gobs more detail. Even if you take the ISO all the way up with the D3 and compare that file to the 1600 ISO D300 or D200, you'll see far more detail. This might be the often discussed full-frame advantage. Quite extraordinary. Makes me lust for a D3, however new windows for the house are more important right now ;-)
