Summary: The D3100 is a refinement of the D3000 which now sits at the low-end of Nikon's entry-level DSLRs. The notable changes are a 14 megapixels sensor and 1080p video capability with autofocus. It is a relatively compact DSLR with the most basic feature set.
Pros: Very low image noise, Excellent white-balance, Conservative metering, Accurate autofocus system, Short shutter-lag, Good shot-to-shoot speed, Excellent time-to-first-shot, Generally good ergonomics, Full HD video with autofocus, Good build quality, Easily usable with gloves on
Cons: Slow autofocus, Uneven color response, Slight image softness, LCD glare when settings are changed, Live-View not exposure-priority, Microphone records camera noise, Impossible to setup video framing, Limited interface control, No exposure bracketing, Odd Auto ISO behavior, Exposure steps always 1...
Excerpt: The D3100 is a welcome update to earlier entry-level DSLRs from Nikon, which offered aging sensor technology and limited feature sets. The D3100 sports a 14.1MP CMOS APS-C sensor with very good low-light capabilities for a camera in its class.
Pros: Lightweight and compact; low cost; good low-light performance.
Cons: Body balance feels awkward; limited manual (but built-in guide is useful)
Summary: The D3100 is a compact, feature-packed DSLR from Nikon. It has many useful upgrades from the existing D3000 and is looking to establish itself as the best entry-level DSLR for consumers. This review explores how good it really is, and includes some sample images to show what you can expect.
Summary: With the addition of video and live view, Nikon has given its entry-level DSLR all the features its predecessor seemed to be missing. The result is an excellent beginner's camera that encourages the user to grow into it, whatever their existing level of knowledge.
Pros: Very good image quality, Unintimidating interface, but with plenty of manual control, Easily accessible Live View and Movie controls, Useful drive mode lever (unique on an SLR at this price level), Highly sophisticated AF system for the price, Easy manual selection of off-centre AF points, Unusua...
Cons: Slight tendency to overexpose in contrasty conditions, Buggy Live View / Movie Mode (movies aren't necessarily recorded at set aperture), Crude live view magnification is of little help for critical manual focus, No live histogram in live view, AF still a little sluggish in live view mode, full-t...
Excerpt: This review got off to a bad start: the DX format camera arrived just before a long holiday break… without a battery and fitted with a less than ideal (for review purposes) f4.5/55-300mm lens (equivalent to 82.5-450mm on an SLR).
Summary: Arriving in the marketplace about mid September 2010, the D3100 became Nikon’s new entry-level DSLR. While the D3000 and D5000 remain on Nikon USA’s website at this writing, you can bet those cameras are on their way out of the picture.
Pros: Good color, image quality, Light and compact DSLR, Decent kit lens
Cons: Short video record time, Noticeable rolling shutter
Summary: The new 14 Megapixel sensor records noticeably finer details than 10 Megapixel models, while noise levels are kept in check at high sensitivities – indeed as you'll see in our results pages, the D3100 performed similarly to the pricier Canon EOS 550D / T2i, at least when both were equipped with...
Pros: 14 Megapixel sensor with great quality., Friendly goal-oriented GUIDE mode., 1080p HD video with autofocusing., Decent metering and 11-point AF system.
Cons: Relatively expensive for an entry-level DSLR., Continuous AF in movies can be slow and noisy., No bracketing, DOF preview or AF with non AF-S lenses., Changing multiple settings requires many clicks.
Summary: The basics The Nikon D3100 is the latest entry-level DSLR from one of the nation's most popular camera manufacturers. With the same mini-me styling as proper pro cameras, and stunning photo quality, it's a great step up for those wanting to upgrade from compact cameras.
Pros: Despite sitting at the low end of Nikon's digital SLR range, the Nikon D3100 is an excellent camera. It features similar styling to much more expensive cameras, with an oversized handgrip, and it's a robust and well made solution. The kit lens is particularly impressive. It offers impressive colo...
Cons: The Nikon D3100 is competing in an increasingly crowded market, and it struggles to differentiate itself. It's good, yes, but there are also impressive options available from Canon, Olympus and others. The D3100 also lacks manual controls when filming videos, stopping you from adjusting certain s...
