某老外在Nikon发布会试机后谈了3点对新机的体会。原文如下:
A brief in-person evaluation: I spent a little time playing with the new cameras, and have three observations to share with our readers:
The D3's high ISO is really impressive I'll remain at least somewhat skeptical until we can get a D3 back in the lab and test it under controlled conditions, but Nikon showed some incredibly impressive prints at the event. They had enlargements that must have been 30x45 inches or more in size, comparing identical shots taken with the D3 and Canon EOS-1D Mark III at ISO 3,200 and 6,400.
After the disappointment of the D2H, I have to say I was taking Nikon's claims of low noise at high ISOs with a rather large grain of salt. When I saw the aforementioned prints though, I was literally flabbergasted. The D3 didn't just surpass the 1D Mark III, it far surpassed it. Well, that may be a little strong; the Mark III is a fantastic camera, but the difference between its images and those from the D3 was anything but ***tle. As I say, I'll remain a skeptic until we can test a production sample of the D3 ourselves, but if the images shown had any basis in reality (and Nikon would be foolish to have doctored them in any way), it looks like there's a new leader in the high-ISO / low-noise derby, and it's the D3.
The optical viewfinder i***ig, bright, and beautiful If you just look at the specs, you might think that the D3's optical VF is a step backward from that of the D2Xs. After all, the D3's viewfinder is rated at only 0.7x magnification factor, vs. the 0.86x of earlier models. You have to stop and take into account the fact that that's 0.7x relative to a full-frame sensor though, so the net effect is something like a 70% bigger view of the world (if my jet-lag-addled brain is doing the math right). However the numbers come out, the D3's viewfinder i***ig and beautiful, something that you won't get by reading the specs.
The new rear-panel LCD is stunning. Nikon's marketing arm has come up with the phrase "Stunning Nikon." I don't know, "stunning" is a pretty strong word. I'd have no problem applying it to the D3 / D300's rear-panel LCD screen though. It's amazing how big a difference the combination of a 3" diagonal size and 920,000 "pixels" makes. Like all LCD specs, that should properly be called "dots" rather than pixels, that's the total number of red, green, and blue points on the screen. Most digicam LCDs have 230,000 dots or less, equating to a 320x240 pixel display. With 920,000 dots the D3 and D300 share a resolution of 640x480 pixels. Images just leap off the screen at you, and the 170 degree viewing angle makes it easy for others to see them as well. (Or for you to see, if you're holding the camera over your head or down close to the ground, in Live View mode.) Stunning.
