Sensor
24 MP FX 24 x 35.9mm CMOS.
6,016 x 4,016 native LARGE (24 MP).
4,512 x 3,008 medium (13.5 MP).
3,008 x 2,008 small (6 MP).
Also crops of 1.2x (20 x 30mm), 1.5x DX (16 x 24mm) and 5:4 professional (24
x 30mm) from the above.
ISO
ISO 100 - 12,800 in in full, half or third stops.
ISO 50 to ISO 204,800 available in stupid modes.
White Balance
Auto (2 types), incandescent, fluorescent (7 types), direct sunlight, flash,
cloudy, shade, preset manual (up to 4 different settings can be saved and
recalled), 2,500 K to 10,000 K in 10K intervals; all with fine-tuning!
Frame Rates
10.5 FPS with full metering and autofocus for each frame.
(11 FPS with locked focus and exposure).
AF
CAM3500FX sensor.
51 AF points (15 are cross-type sensors).
Works with auto- and manual-focus lenses f/5.6 and faster.
11 of these sensors will work with lenses as slow as f/8.
AF range is rated down to LV-2 with any lens. (SLR AF systems have never
used the full speed of lenses; they look through anulii equivalent to about
f/8 regardless of lens speed.)
Finder
100% coverage.
0.7x magnification (50mm at infinity).
18mm eyepoint.
-3 to +1 diopters.
Live-View LCD.
Meter
Nikon invented the Matrix Meter, the color meter and the 3D meter, which is
what really matters.
For the first time, Nikon is wasting their time by upping the resolution of
the meter sensor for marketing purposes to 91,000 RGB pixels.
It also measures flash at this resolution.
Shutter
Kevlar/carbon fiber-composite, rated 400,000 shots.
1/8,000 - 30 seconds in full, half or third stops.
Bulb.
X 250 flash sync.
"Silent" mode.
Flash
1/250 flash sync.
i-TTL flash control using the 91,000 pixel RGB sensor with the SB-910, SB-
900, SB-800, SB-700, SB-600 and SB-400.
Won't meter flash with other flash guns.
Lens Compatibility
Built-in motor and AI coupling feeler, so all AF lenses work, as well as
classic AI, AI-s and AI-P manual-focus lenses all work as well as they do on
all of Nikon's better DSLRs.
File Formats
JPG.
NEF 12 or 14 bit, uncompressed, or lossy or lossless compressed.
NEF + JPG.
TIFF.
Video: H.264/MPEG4 stored in .MOV files.
Storage and Data
One CF slot (UDMA 7), and one XQD slot. (NOT two CF slots).
XQD cards are bogus — Lexar doesn't make them, and I don't know about
SanDisk. Therefore, the XQD slot is largely useless. I'll only use Lexar and
SanDisk cards. Got a XQD reader? I didn't think so.
USB.
HDMI (mini-C).
RJ-45 Ethernet.
Wireless
WT-4 or WT-5A/B/C/D.

1,920 × 1,080 (full or cropped) at 29.97p, 25p and 23.976p.
1,280 × 720 at 59.94p, 50p, 29.97p and 25p.
640 × 424 at 29.97p and 25p.

Size
6.3 × 6.2 × 3.6 inches.
160 × 156.5 × 90.5 millimeters.

发帖数: 3616 | 2 D4s不是应该是高感机吗？D610虽然高感不错，但和D3s还是有差距的。搞D4s不太可能
吧 | J*********n
发帖数: 6974 | 3 我也是这么觉得的，不过把D610的CMOS装到D4机身上，用EXPEED 4 Image Processor，
这绝对是一台很好很平衡的机器，除了价格，秒5D3是没什么问题的。 | J********o
发帖数: 17447 | 4 这样的话1Dx就完全没优势了... 也就因为像素低高感吧, 1dx高感是真bt | J*********n
