The Nikon D300

Everyone who had followed the Nikon and Camera brands of SLRs over the past several years expected that Nikon would bring out models to compete with the new Canon models. So it is no surprise that they have with the Nikon D3 and Nikon D300. The D3 is the first full frame (that is, the sensor is the size of a frame of 35mm film) that Nikon has produced. And that is all I am going to say about it, because lusting after it (price $5,000) will not get me one, and the D300 has many features that make it interesting and desirable in its own right.

Features of the Nikon D300
It has 12 megapixels compared to the 10 megapixels of the D200, so the change in image quality from the pixel count is so small as to be discounted. But the sensor uses CMOS technology, unlike the D200, which has a CCD sensor. And it is a proprietory Nikon sensor. And the image processing is 14-bit.

These three features imply that the image quality will be substantially improved over the D200, that the high ISO image quality will be tremendously improved and that battery life will also be improved.

14-bit
The extra bit depth of 14-bit technology (rather than the 12-bit that Nikon and Canon employ at the moment) should mean fewer blown highlights. Blown hightlights occur where an overdose of light hits all or some of the microlenses and reduces the image on those parts of the image to blank white, from which no detail can be recovered.

Small areas of blown highlights are often not a problem, but it’s a different story if it affects all the white petals on a flower, or the bride’s white dress, or the side of someone’s face that is turned to the sun. Compact cameras are notorious for blowing highlights, mainly because each microlens in the array is so small that it is easily overcharged in a high contrast scene.

14-bit technology means more steps are capable of being read between dark and light, which should result in a smoother gradation from dark to light areas.

Whether this increase in bit depth translates into images that looks good depends on the processing technology within the camera. That is something we will have to see when the first images are taken and the samples posted. I hope to post some samples. The potential is there – it remains to be seen how well Nikon (and for that matter Canon with their offerings) translate this into images that have the pzazz of a well-converted 8-bit jpeg.

Thankfully, photography is still at the mercy of the light striking the sensor chip. Which means that attractive lighting – early morning light on a dull day, late afternoon winter’s light, gentle north light filtering into a room – still drives the photographer’s quest for what will make a good image.

CMOS and CCD technology
With a CMOS sensor chip, the electronic charge generated by the light hitting the microlenses is amplified via transistors on each microlens and the values are read individually. With CCD technology, the charge across the whole array of microlenses on the sensor chip are read at one corner of the array. Both technologies are capable of making high-quality images but Canon, using CMOS technology, has shown that this seems to have a distinct edge at high ISO.

And this for me is the real break with traditional 35mm photography, because the ability to shoot at ISO 3200 and get clean images, takes the opportunities for where and when one can photograph, into a place that was unknown to film photography.

With a fast lens – say something between f1.8 and f2.8, one can think of taking atmospheric portraits in low light that were not possible with film – at least not without flash (which changes the scene completely) or without using very high speed film that had its own limitations.

One of the other advantages of CMOS technology is that it is less demanding on power. This should mean improved battery life for the D300.

More features
Add to the features of the D300, a self-cleaning sensor, an LCD that has an astounding 922,000 pixels (the D200 has 230,000), liveview in the LCD (so you can see what you are going to shoot, rather than just what you have shot), and dimensions and weight more or less the same as the D200, and Nikon have probably held on to their lead. The lead they have built over the past six months is that they have outsold Canon SLRs.

D300

Whether it is the big guns like these cameras that are making the difference, or whether it is the D40 that is giving Nikon its lead, I don’t know. One thing that is clear though, is that both manufacturers are still in the game, which benefits consumers of all stripes. It would have been a pity if one or the other failed to make advances in technology, for that would only mean the market would stagnate.

And as for images of the new cameras from Nikon, well Nikon is kind enough to supply a whole page of web-ready images for people to use. Which strikes me as a sensible sign of the times when a manufacturer gets everyone who wants, to be an ambassador and advertiser for its products.

  1. It will be out ‘soon’. Probably in the shops in the U.S. within a week or two, or three…

    I have found the D200 to be very good indeed at keeping clean, without sensor cleaning.

    So it is hard to know how much people will notice the improvement with the D300. The D200 is weather-sealed.

    Of course if you change lenses there is always a risk of dirt getting in but I suspect a bigger opportunity for dirt to get in is from mounting cheap lenses that have poor internal sealing.

  2. I am looking for my second camera and did check out this D300! I am very glad to see that this camera is using the Compact Flash Card! Only wish the price was down but maybe the D200 will get cheep enough that I might be willing to get that instead!

  3. I am going to put a couple of shots on this site, taken with the D200 with the Nikon 105mm f2 DC lens, which is very sharp.

    It is a hard lesson to learn, but if the D300 is too expensive, spend money on good lenses.

    Another good ‘long’ lens is the 180mm f2.8 ED. It is a great lens and images really ‘pop’.
