Features explained

Nikon’s affordable, compact and lightweight, the D3100 is an entry level DSLR from Nikon featuring a DX format 23.1mm x 15.4mm CMOS sensor. It offers a healthy 14.2 megapixels that should be more than enough for any type of photography.

ISO Range

The D3100 has an ISO sensitivity range of 100-3200. At Hi-1 and Hi-2 modes it is further sensitive to ISO 6400 and 12,800.

Auto-focusing points

When comparing between the D3100 and the entry level offerings from Canon such as the 1100D or the 550D and the 650D, they have only a 9 point auto-focusing system. The D3100 has a 11 point auto-focusing system. Technically though there is a difference, the extra 2 point does not make that much of a difference.

Viewfinder & coverage

The D3100 has an eye-level pentamirror SLR viewfinder. If you’re confused as to what is a pentamirror, then it is a cheaper variety to a more professional option of using a pentaprism. The brightness of the pentamirror viewfinder is less compared to a pentaprism viewfinder. The D3100’s viewfinder gives 95% frame coverage basically it means you capture more than you see through the viewfinder.

LCD Display

The back of the camera is dominated by a 3” 230,000 dots resolution TFT LCD monitor. This is probably where the D3100 really loses out on other entry level DSLRs. While other competitors have migrated to a brighter 921,000 dots or even 1,040,000 dots resolution, this leaves a lot to ask.

AF motor

However the D3100 has a definite disadvantage in the lack of auto-focusing capability with some of the older Nikkor lenses. These lenses don’t have an auto-focusing motor built in and rely on the AF motor of the camera which the cheaper entry level DSLRs like the D3100 does not have. If you’re planning to use a modern G type Nikkor lens or anything else which comes with a built-in auto-focusing motor then this camera is just perfect for you.

Stills & movies

The 14.2 megapixels sensor produces the largest image size (by pixels) of 4,608 x 3,072. The D3100 captures full HD movies in 24 fps. At 720p HD it can capture videos in 30 fps. The built in microphone can capture monaural sounds.

What’s missing & wish list

The camera can surely do with the option for plugging an external microphone jack. Also it does not have a built-in AF motor which makes it impossible to use older AF lenses.

Similar products

Two cameras immediately comes to my mind first is the Canon 550D/Rebel T2i and the 600D / Rebel T3i. They are both available at a similar price of $699. Another camera that should be mentioned is the Sony Alpha a65 which retails also at $699 but has one of the fastest continuous drive of 10 fps.

Should I buy it?

The D3100 is a very light DSLR something that should appeal to first time DSLR users. Although it’s more powerful and much younger sibling (D3200) has been out for a few months, the D3100 is still going strong. I hope Nikon keeps it going for some more time as it is a great camera. The D3100 is a lot lightweight too (455 grams without lens and battery). Comparing with some of the older models such as the D90 or the D40, the D3100 has certainly lost a lot of bulk. A good thing too, if you’re migrating from a compact / point & shoot and the thought of a big bulky DSLR intimidates you. Unless of course you have the money to indulge in a full frame DSLR or your definition of better photography begins with more megapixels then the D3100 is a perfectly good DSLR to begin with. Available at Adorama | AmazonB&H
