The D3100 is built around a 14.2 megapixel CMOS sensor (quite possibly the one seen in Sony’s NEX cameras), bringing not only live view but also Full HD video capture to Nikon’s entry-level model.
The Dpreview announcement says the AF is during Live View, keeping the selected area in focus without needing to press the shutter button. No mention of AF during video, unless I missed that.
With the right price, this camera is a serious threat to Canon and Sony’s offerings. Unfortunately this camera outspecs the A290 and A390 that one would ask: why bother with these two?
Sony is gonna have to play catch up again in this department. Brace yourselves for the A295 and the A395 coming up in 3 months…
Good specs for an entry level cam, but remember not AF with full frame lenses (G or D AF Nikkor). Also, it is going to take a while before the price will drop. So that leaves room for the a290/390. For anyone on a budget, the question will be to either spend £350 on a a290 or £579 on a D3100 (or still go for a D3000 or D5000, which also don’t support AF for FF lenses).
So, it is always about compromise. No need to constantly complain about Sony.
@FreeRadical09 – Original announcement says: “AF-F (full-time servo AF) focus mode for movie recording” right in the headline.
Though it’s contrast AF only.
@emopunk – those “meaningless” cameras overkill D3100 in some specs. Most notably they are bigger, more comfortable (D3000 was poor in this matter, so D3100 will be most likely too, as I don’t see any improvements), cheaper, and can use cheap, legacy glass (Nikon has it’s screwdrive cut off). A290 have notably better OVF than Nikon, and can survive longer on a single battery, while A390 have much much better live view, and the tiltable LCD.
So all in all the entry-level Sony DSLRs still hold the ground.
To me more interesting is that Nikon introduces 24-120mm F4 G ED VR lens for 1000USD. When Sony will do the same?
What impressive over NEX (for example)?
D3100 video limited to 10min.
Nothing mentioned about phase detection AF in video, just servo AF (I think interrupts video during focusing).
Mono-sound.
3-in., approx. 230 k-dot TFT LCD
This camera is nothing special, but an attempt to keep some brand faithful consumers from looking at the rest of the market.
Sure it has HD video, but most other DSLR’s with video do the same, it will only be contrast AF in video and quite frankly is not ideal unless you like to shoot inanimate objects.
I believe they released the D3100 because they felt they needed to, not because they wanted to and its stop gap model to buy some time as they play catch up now.
If Video in an SLR is important, the Sony system would have to be a clear number by a long margin over anything else in the market place.
Q – hehe, funny, cause Nikon fans from dPreview already hyped the camera:
“Nikon has announced the D3100 – probably the biggest refresh of its entry-level offering since it really attacked the low end market with the original D40.”
^ I agree with you, it’s nothing more than a refresh, though dPreview guys found it to be immerse breakthrough… lol
Sadly it is the same story over again… Nikon designs an improved version of the sony version and they end up being sharper, with less noise at high ISO´s, etc….
It has never been a secret that Nikon manufactures the sensors at Sony´s plant, however histoy has always proven that sadly Sony has no idea on how to deal with sensors (A100 vs D80,D200- A700 vs D300,D90)
It is like the so called Zeiss lenses… the ones even Zeiss says in their faqs that aren´t manufactured by them -tip cosina makes them ;)-
The D3100 DOES recording during video. From their press release:
“4. D-Movie for recording and editing full-HD movies and AF-F (full-time servo AF) focus mode for movie recording.
…
When AF-F mode is enabled, the camera focuses continuously during movie recording without the need for holding the shutter-release button down halfway.”

And so Nikon is now an author of first DSLR with AF during video.
Less than a week before Sony. ~_~
IQ and high ISO performance should be excellent on the D3100 considering it’s an entry level model.
AF during movies is also excellent considering this is targeted at first time DSLR users.
The only downside I can see is the lack of stereo audio recording. Mono mic and no mic input 🙁 1080p with mono audio? GRR
same sensor?

says “The camera is equipped with a new CMOS image sensor developed by Nikon”
how sony will sell A290/A390 ? D3100 is really impressive
The ugliest thing I ever saw
from dpreview:

@max, they’ll have to sell them a hell of a lot cheaper lol
I can’t wait to see what Canon’s response to this will be. The 1000D looks like it’s from the stone age now and is due for a replacement.
wow,Full HD 1080p 24p
This shows once more how meaningless A290 and A390 were when they hit the market. I hope they disappear very soon from the shelves.

SonyAlphaRumors Nikon advertises. Buy it, because in addition to Sony a290 and the A390 does not make anything out of the APS-C.
???
looks impressive but why did Nikon remove AE Bracketing?
@Me,
Correction: No AF with D lenses. Full frame G lenses will do fine with the 3100.
To me more interesting is that Nikon introduces 24-120mm F4 G ED VR lens for 1000USD. When Sony will do the same?

nikon used same wording to describe their D200’s sensor. But we all know where is the 10MP ccd sensor came from
Sadly it is the same story over again… Nikon designs an improved version of the sony version and they end up being sharper, with less noise at high ISO´s, etc….

D3100 sensor: 23.1 x 15.4 mm
NEX sensor: 23.4 x 15.6 mm
The D3100 is equipped with a new Nikon DX-format CMOS image sensor and a new image-processing engine, EXPEED 2, both developed by Nikon.
