I also obtained a D3100 a few weeks ago for 1880RM (S$782) in Penang (with AFS 18-55 VR, 4G SD, Bag). I have previously used A200, 1000D and D60.
I like:
- It provides much more value than its price. I guess Nikon has done a mistake by putting too much capabilities in a very cheap camera.
- I am very very happy about the ISO performance. Noise level on ISO3200 is equal to noise level at ISO800 on A200, D60 and 1000D cameras. The ISO 6400 and 12800 are usable to some extent. You can capture things with a bit light from nearby street lights without flash.
- I am more happy about auto white balance than my previous cameras
- I like the VR performance in 18-55 kitlens. It is 2 times more effective than my canon EFS-18-55 IS (possibly had IS problems?). With VR enabled I can take 1/8s photos without problem while on my canon 1/16s was the best I could do.
- Video mode at least provides a mediocre auto-focus. Much more expensive cameras like 550D do not provide even this.
I don't like:
I don't like a few things. I wish future firmware releases will do something about that.
Autofocus: I have a high rate of our of focus photos with the kitlens AFS-18-55. I am using single point, single servo focus and the shots are mostly from still, non-moving objects. So this cannot be because of incorrect AF setting. I am forced to shot with higher F to decrease the problem.
Out of focus shots are much more than what I used to have with 1000D (with 18-55) and almost equal to A200 with 17-80 and 55-300.
Auto Mode not usable: The other day I was convincing my friend that D3100 is enough for his need and he does not need to pay much more to buy a 550D.
We visited a shop, inserted our own SD cards and put both cameras on Auto and took 30 shots. Later I found that D3100 has taken all the photos with Hi2 (ISO12800) while 550D has selected ISO400-ISO800 exactly in the same situation with an almost the same lens (both with 18-55, F3.5-5.6).
As a result shots from D3100 are terribly noisy. My friend immediately selects 550D. I myself never take photos on Auto-Mode but if I ever want to hand it to an inexperienced user to take photos the problem will hit me too.
Metering with open Flash incorrect: With closed flash in a specific situation, camera would auto select ISO3200. Opening the flash does not have any effect and camera still auto selects ISO3200. Ken Rockwell refers to the same firmware bug in his review.
Underexposure: My camera underexposures a lot of times. As a result I have a +0.3 exposure compensation setting most of the time.
Video laggy: You can easily see lag in 1080p video if you pan the camera. This can also be seen in 720p mode, but in less amount. I guess this is related to the power of the CPU on board. A new firmware might not increase the performance by reasonable amount since this is hardware limitation.
Additional features: This is a very cheap camera and as such I should not expect more. But anyway this is the list I would like to see
- Bracketing
- Swivel LCD
- 1-2 more control buttons on the body
- A bit more powerful CPU
- In-body motor of course
I understand that no camera is perfect (I had different problems on A200, 1000D and D60). But I appreciate if anybody can suggest workarounds to the mentioned comments of mine.
Thanks.
