Clearly more megapixels (photo)
18.23% more megapixels (photo)
Much larger sensor
15.6 x 23.5 mm
15 x 22.5 mm
8.62% larger sensor. The larger the sensor the more light the sensor captures yielding in better image quality.
Substantially more focus points
32 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.
Distinctly lower noise at high ISO
35.64% lower noise at high ISO. The maximum ISO at which the device still captures excellent quality images. Source: DxOMark.
Vastly better image quality
15 better image quality. A device's overall image quality score considers: color depth, dynamic range and low light performance. Source: DxOMark.
80 g lighter
Considerably better video recording quality
1080 x 60 fps
1080 x 30 fps
2x better video recording quality
Plenty better color depth
7.56% better color depth. The better a device's color depth the more color nuances it can distinguish. Source: DxOMark.
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.
Longer battery life
30 shots longer battery life. CIPA is an independent, standard measurement that determines how many shots a camera can take before the battery dies.
A little bit more battery power
5.56% more battery power
Substantially higher resolution
18.01% higher resolution
Explicitly wider dynamic range
18.10% 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.
Modestly less body volume
4.20% less body volume
Has a built-in focus motor
The focus motor moves the lens in order to autofocus. With it built into the camera, you still have the function when using a lens without its own motor. This allows you to use a wider range of lenses.
Significantly higher resolution (screen)
1228 k dots
1040 k dots
188 k dots higher resolution (screen). A higher screen resolution provides a sharper image, making it easier to review your photos.
A little bit narrower
3.50 mm narrower
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.
A little thinner
3 mm thinner
Sizably less shutter lag
0.01 s less shutter lag. The amount of time it takes the camera to take a photo, without having to focus.
Significantly less startup delay
0.02 s less startup delay. It takes less time for the camera to turn on and take a first picture.
Modestly bigger screen size
6.67% bigger screen size. The bigger the screen size is, the better the user experience.
Has timelapse function
A timelapse shows a long passage of time sped up. A series of photographs taken from the same position over a long period is joined together to create a short video. It is great way to capture things like the setting sun, or clouds moving across the sky.
Has dual card slots
It has two memory card slots, allowing you to store more photos without switching cards. This is particularly useful on long shoots when you need more space.
