Lens Compatibility
The D3100 has no AF motor of its own, so just like the D5000, D3000, D60, D40 andD40x, it only autofocuses with newer AF-S (or old professional AF-I) lenses. With traditional AF lenses, you'll have to focus manually, which is a pain. There is no metering with manual-focus lenses, except with oddball AI-P lenses.
11 points.
95% coverage.
Lightweight, smaller pentamirror.
0.45x magnification with standard 28mm (for DX) lens. (0.8x with 50mm lens, which is a telephoto on a DX camera.) 18mm eyepoint.
-1.7 to +0.5 diopters.
Trade name of screen: "Type B BriteView Clear Matte Mark VII screen." Wow!
420-segment 3D, full-color Matrix meter, center-weighted or spot.
Canon's best cameras still only see in black-and-white, and Canon's newest 7D only sees in two colors, not full-color as have most Nikons since the F5.
Built-in flash, GN 12 meters (39 feet).
Nikon says that "Advanced Wireless Lighting supported with SB-900, SB-800, or SU-800 as commander," which implies by exclusion that the built-in flash will not work as a remote commander for external flash. Nikon is weaseling out of just saying it won't work. Maximum shutter speed with flash (sync speed): 1/200. Nikon also shares that Flash Color Information Communication is supported with the built-in flash and all CLS-compatible flash units.
PC (Prontor-Compur) Sync Terminal for studio strobes: No, but Nikon will sell you aSync Terminal Adapter AS-15 to add it, but heck, I use an old Nikon SB-30 flash on my cameras as a remote trigger for my studio strobes instead of a PC cord.
1/4,000 to 30 seconds in third stops and Bulb.
2s or 10s self-timer.
Single, Continuous (3FPS) and Quiet advance modes.
"Tested to 100,000 cycles."
14 MP CMOS DX (23.1 x 15.4 mm) 4,608 x 3,072 pixels native, also 3,456 x 2,304 [M] and 2,304 x 1,536 [S] settings.
Sensor cleaner.
ISO: Auto, 100-3,200 in full stops, also ISO 6,400 and ISO 12,800.
White Balance: Auto, incandescent, fluorescent (7 types), direct sunlight, flash, cloudy, shade, preset manual. All except preset manual offer fine tuning, which is a bit of a bummer, since I like that my D3 offers trims on gray-card balances. I'm unsure if there are five gray-card memories as on more advanced Nikons.
Picture Controls: Gen 2: Standard, Neutral, Vivid, Monochrome, Portrait, Landscape; selected Picture Control can be modified. Adaptive Dynamic-Range Control: Yes, ADR is as expected in Gen 2.
1,920 x 1,080/23.976p, only. (no 25, 29.97 or 59.94 ability.)
1,280 x 720/29.97p, 25p and 23.976p. (no 59.94 ability.)
640 x 424/23.976p, only, which is a useless 3:2 aspect ratio.
It's interesting to note that Nikon just can't keep up with the video resolution of Canon's DSLRs like the 7D and 5D Mark II. At 1,920, the Nikon can't run at the faster 25.00 and 29.97 fps rates, which is OK since Hollywood shoots at 23.976 anyway. At the faster 25 and 29.97 rates, this Nikon can only shoot at 1,280. Canons also shoot at 59.94p in 640 and 1,280 for fluid motion. Maximum Recording Time: 10 minutes.
.MOV files holding H.264/MPEG-4 data.
Audio: Internal mono microphone, linear PCM recording.
In-Camera Editing: Can clip from the beginning or end of a movie.
3."
Lower-resolution 230,000 dots (not 920,000 like the D90, D300s and D3s).
SD, SDHC or SDXC card, up to at least 64GB today.
USB.
Type C mini-pin HDMI connector.
NTSC and PAL.
EN-EL14 Battery.
EN-EL14 Li-Ion battery, which is, at least as of October 2010, unique to the D3100 and the P7000. Cells made in Japan, assembled into a battery in Indonesia.
The great news about the charger is that Nikon finally got smart and gave it a folding plug, not another cord we need to carry.
It's rated for use worldwide: 100-240V, 50-60 cps. Just bring the right passive plug adapter, plug it in, and you're good to go, without any cords!
Optional AC adapter EH-5a and EP-5 power connector
