Nikon D3100 review – Verdict
Although the Nikon D3100 may stretch the ‘entry-level’ price point (thus its biggest drawback on the score board), it equally stretches the sheer amount of specification you’re getting too. Usually always on the money, it’s only the slightly sluggish autofocus during live view (and, therefore, movie mode) that may frustrate.
Small niggles mean no Depth of Field preview and the burst rate isn’t the fastest. On the plus side though the images are great, Guide mode will see newcomers quickly unleash their potential, and pound for pound there’s essentially nothing else (currently) out there to match the specification head on.
All things considered, the D3100 is nothing less than the best entry-level DSLR available at time of review.
