I'm glad I skipped the D200, stuck with my D70 and spent what I would have done on lenses instead. Don't chuck the D70 just yet: you may find yourself better off using D70 images straight than noise reducing and downsampling D300 images in low light. If Nikon made the D300 with worse noise than the D200, then IMO that's a mistake if the option was to stay at 10mp and improve noise performance. But my guess is that it's going to be good (but no - not a 5d). Take a D2xs sensor and add a few years of development, and it darned well ought to be improved. And no - the D70 has been excellent, but it's time to move on. At about 30,000 clicks, Even if I trashed it now, I've saved more than 5x what it would have cost me in film and processing, and the results have generally been better, sometimes much better than I ever got from 35mm. I shoot raw, and use an R1800 for printing. Viewing my old Cibachrome collection shows me very clearly how much things have moved on in a relatively short space of time. The D70's great for IR photography, whereas the D200 and, I assume, the D300 are not. Keep it if you can afford to. People worry that adding the extra pixels to the sensor will make the D300 noisier, but if DPReview is right, the D300 uses a CMOS instead of CCD, and thus may alleviate that problem to some degree. -- www.mattclara.com |

It's unique in that it has/had 12 MP at a fine pixel pitch. It is one of the noisiest DSLRs made in recent years, though, as far as read noise is concerned. It has more read noise at ISO 100 than the 1Dmk3 has at ISO 1600. It's a camera that works best in controlled lighting; not for action in dark places. -- John P Sheehy |

: ROFL, then every camera used for sports before digital must be a joke, too! And yet they got good photos anyway! Did they, really? Most of the action sports and wildlife photos in low light from the age of film look pretty poor (IQ-wise), IMO. -- John P Sheehy |

I don't remember those shots, John, I remember the 20 x 30 poster of Dr. J. slam dunking it from the free throw line, etc. All excellent shots. What sports were you interested in that they happened in low light? I think you're making **** up, is what I think. Helps your argument, I guess. -- www.mattclara.com |

: [A complimentary Cc of this posting was sent to David J. Littleboy ], who wrote in article : Of course, my reading of figure 5 on this page indicates that there's no point to bothering with a 14-bit A/D converter on either this or the 40D. My hunch is that N-bit converter would deliver at most N-1 or N-1.5 usable bits. If so, then using 14-bit converter makes sense even if only 12bit is needed FOR STORAGE. That's my thinking as well; if there is some benefit in the 14-bit ADC, you might not need 14 bits in the output. Comparing the deep shadows of a 14-bit ISO 100 RAW from the 1Dmk3, and a 12-bit version of it (the 2 LSBs zeroed), with exactly the same RGB interpolation and WB, there is no significant difference, even pushed to ISO 2800. So, even *if* the 14-bit data had less analog noise underlying it, having the 2 LSBs in the RAW is of questionable value, in terms of what you get vs what it costs you. Personally, I think that only the cleanest of DSLRs warrant even 12 bits at ISO 100 (Pentax K10D, Fuji S5, Canon 1D(s)mk*, etc), and that 10 or even less bits are needed at ISO 1600. The D2X could probably get away with 8 or even 7 bits at ISO 1600 - read noise is about 60 ADU at 12 bits, and that would still be almost 4 ADU at 8 bits. I just tried it - zooming in to 640 RAW levels from the shadows of the blue channel of a D2X ISO 1600 file (IOW, pushed to about ISO 5100), mapped to 0 to 255 on the screen, I can see almost no difference whatsoever in the quality of the original 12 bits, and after integer- dividing and -multiplying by 32, for an effective 7 bits of RAW data. At 6 effective bits (read noise is now about 1 ADU), I start to see a slight unevenness in tonalities. At 5 bits, it is obvious, and at 4 bits, the greyscale image becomes severely posterized. -- John P Sheehy |

The D40 is a much better imager for low light at 6MP. Still might not be as good as the D300 downsampled to 6MP, though (not that I recommend downsampling images just to reduce pixel-level noise). Have to wait and see what the new Nikons really do. -- John P Sheehy |

Time marches on, but some people just sit down and mope. Some people are so taken in by new technology that they automatically assume it must be an improvement on older technologies. And once having invested expensively in the new technology, they flat deny that old technologies had anything to offer, for fear of buyer's remorse. Fortunately for the rest of us, these people are totally transparent. |
