Top 17 Reasons for the
Compared to Canon EOS 550D
Clearly larger sensor
15.6 x 23.6 mm
22.3 x 14.9 mm
10.80% larger sensor. The larger the sensor the more light the sensor captures yielding in better image quality.
Substantially lower noise at high ISO
46.59% lower noise at high ISO. The maximum ISO at which the device still captures excellent quality images. Source: DxOMark.
Clearly more focus points
2 more focus points. The more focus points the more flexibility in picking which part of the scene to focus on. They also give the image sensor a better probability in identifying the right area of the scene to focus on in more automatic modes.
Significantly faster shooting at highest resolution with AF as JPEG format
33.33% faster shooting at highest resolution with AF as JPEG format. Fast continuous shooting is useful for catching action shots.
Has a flip-out screen
Flip-out screens are useful for doing tricky shots.
Vastly better image quality
14 better image quality. A device's overall image quality score considers: color depth, dynamic range and low light performance. Source: DxOMark.
Substantially higher maximum light sensitivity
2x higher maximum light sensitivity. With a higher light sensitivity (ISO level), the sensor absorbs more light. This can be used to capture moving objects using a fast shutter speed, or to take images in low light without using a flash.
20 g lighter
Reasonably better color depth
6.82% better color depth. The better a device's color depth the more color nuances it can distinguish. Source: DxOMark.
Has a 24p cinema mode
24p is a video format (24 frames per second) traditionally used in cinema. Nowadays, it is used to create film-like motion characteristics.
Has a built-in HDR mode
It can automatically shoot pictures with a higher dynamic range (HDR).
Measurably wider dynamic range
17.24% wider dynamic range. The better the dynamic range the system captures a wider number of values from dark to light leading to more details in low and highlights. Source: DxOMark.
Has continuous autofocus when recording movies
When recording movies they stay focussed and sharp.
A shade narrower
1.80 mm narrower
Explicitly longer battery life
220 shots longer battery life. CIPA is an independent, standard measurement that determines how many shots a camera can take before the battery dies.
More lenses available
7 more lenses available. A bigger variety of brand lenses means that you have more options and can find one that suits your needs.
0.80 mm shorter
Has the same processor
Is quite easy to use every day and the image quality is almost the same due the same image processor. D7000 is more accurate for the focus metering.
