Impressions of the d300
Yes I bit the bullet and bought a d300. It was $1995 on ebay, how could I resist that? my main reason was I have been dabbling more in portraiture these days and I have to manually focus everything, which is a pain. I wanted a camera that could focus better.
Though I have only had the camera a few days and not had much time to play with it, I have taken a couple of test shots with it that I will upload.
My first few pictures were taken to see if the high iso is as good as people have been saying.
Below is the same image taken at f1.8 with the nikkor 50mm at night under tungsten light. Note the differences in colour, they were all taken with the camera's auto everything, however I manually adjusted iso and shutter speed. I've cropped the original as they would of been too large, click on the images to see a larger version.
iso 3200, f1.8 1/10
iso1600 f1.8 1/5
iso 640, f1.8, 1/5
iso200, f1.8, 1.6 secs
Note there is slight noise visible at iso200, though the shutter speed was 1.6 seconds.

ISO Setting in Digital Cameras
What happens when we select a certain ISO value in our digital camera? What is the best ISO setting for our particular camera? Can we change it light-heartedly or does it deserve a more careful consideration? Read on to learn how we can improve our photographs through the right selection of the ISO setting.
Let me give you the bad news, first. Camera manufactures do not disclose strategic and sensitive information such as what happens internally when the user select a certain ISO value. Anyway, through sound reasoning and a little of reverse engineering we can speculate on it and come to meaningful conclusions. In particular, reverse engineering is best performed on RAW file format, rather than JPEG, because JPEG compression introduces artifacts and algorithms complicating the process.
For starters, we need a definition. Image sensors have a so-called native sensitivity. This is the innate or natural sensitivity of the sensor when compared to a standard film. For instance, if the native sensitivity of a certain sensor is 100 ISO, it means that it gives comparable results to a 100 ISO rated film when both are used at the same aperture and shutter speed. Native sensitivity cannot be changed, because it is inherent to a certain sensor. Therefore, when we change the ISO speed setting, something must occur involving the circuitry serving the photosensitive sensor. More specifically, things play out differently according to whether an ISO greater or lower than the native sensitivity is selected. Let us see...
