Sizably more megapixels (photo)
18.23% more megapixels (photo)
Reasonably larger sensor
15.6 x 23.5mm
15 x 22.5mm
8.62% larger sensor. The larger the sensor the more light the sensor captures yielding in better image quality.
Appreciably 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.
Substantially 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.
Distinctly 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.
Considerably better video recording quality
1080 x 60fps
1080 x 30fps
2x better video recording quality
Much better color depth
7.56% better color depth. The better a device's color depth the more color nuances it can distinguish. Source: DxOMark.
Longer battery life
30shots longer battery life. CIPA is an independent, standard measurement that determines how many shots a camera can take before the battery dies.
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 tad more battery power
5.56% more battery power
Significantly higher resolution
18.01% higher resolution
Noticeably 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.
A little less body volume
4.20% less body volume
Explicitly higher resolution (screen)
188k dots higher resolution (screen). A higher screen resolution provides a sharper image, making it easier to review your photos.
A tad narrower
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.
A tad thinner
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.
Significantly less shutter lag
0.01s less shutter lag. The amount of time it takes the camera to take a photo, without having to focus.
Distinctly less startup delay
0.02s less startup delay. It takes less time for the camera to turn on and take a first picture.
A little 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.
