Canon EOS 70D vs Canon EOS 7D
Top 24 Reasons for the
Canon EOS 70D
Compared to Canon EOS 7D
Vastly more megapixels (photo)
10% more megapixels (photo)
A tad larger sensor
15 x 22.5 mm
14.9 x 22.3 mm
1.57% larger sensor. The larger the sensor the more light the sensor captures yielding in better image quality.
Lots lower noise at high ISO
8.43% lower noise at high ISO. The maximum ISO at which the device still captures excellent quality images. Source: DxOMark.
Has a flip-out screen
Flip-out screens are useful for doing tricky shots.
A little bit better image quality
2 better image quality. A device's overall image quality score considers: color depth, dynamic range and low light performance. Source: DxOMark.
Significantly 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.
A bit lighter
65 g lighter
Somewhat better color depth
2.27% better color depth. The better a device's color depth the more color nuances it can distinguish. Source: DxOMark.
A bit higher pixel density
6.37% higher pixel density
Has a stereo microphone
A stereo microphone allows to record audio files or movies in stereo without an external microphone.
The device can connect to WiFi.
Marginally less body volume
5.58% less body volume
Substantially higher resolution
13.18% higher resolution
Has a microphone in
A microphone port allows connecting external high-end or specialized microphones.
9.20 mm narrower
Noticeably longer battery life
120 shots longer battery life. CIPA is an independent, standard measurement that determines how many shots a camera can take before the battery dies.
Has touch autofocus
The autofocus is immediately set to the subject by just touching it on the touch screen.
Explicitly higher resolution (screen)
1040 k dots
920 k dots
120 k dots higher resolution (screen). A higher screen resolution provides a sharper image, making it easier to review your photos.
Has a touch screen
You can operate the device easily, by pressing the screen with your fingers.
6.70 mm shorter
Newer DIGIC version
Newer DIGIC version. Newer image processors are better at processing multiple tasks simultaneously, and can produce higher quality images with better low-light performance and faster AF.
Cross-type focus points
The 70D has 19 cross-type focus points, while the D7100 only has 15
Much faster and more accurate focus in Live-View
Autofocus in Liveview is much faster on the 70D due to the dual-pixel-sensor. It hits the spot nearly every time, unlike contrast-detection.
Canon EOS 70D is better than Canon EOS 7D because...
Top Eight Reasons for the
Canon EOS 7D
Compared to Canon EOS 70D
Measurably faster shooting at highest resolution with AF as JPEG format
14.29% faster shooting at highest resolution with AF as JPEG format. Fast continuous shooting is useful for catching action shots.
Faster video autofocus due to a phase detection autofocus when shooting movies
A phase detection autofocus is much faster than a contrast detection autofocus and allows sharper movies.
A little wider dynamic range
0.86% 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.
Significantly less shutter lag
0.02 s less shutter lag. The amount of time it takes the camera to take a photo, without having to focus.
Faster photo autofocus due to a phase detection autofocus when shooting pictures
A phase detection autofocus is much faster than a contrast detection autofocus and allows sharper images.
Vastly less startup delay
0.05 s less startup delay. It takes less time for the camera to turn on and take a first picture.
5.50 mm thinner
A tad more viewfinder coverage
2 % more viewfinder coverage. With 100% coverage you can compose the image correctly when you capture the photo. With less than full coverage you may have to crop your photos afterwards to get them looking perfect.
