A bit more megapixels (photo)
2.53% more megapixels (photo)
Explicitly more focus points
12 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 faster shooting at highest resolution with AF as JPEG format
20% faster shooting at highest resolution with AF as JPEG format. Fast continuous shooting is useful for catching action shots.
Modestly better color depth
0.83% 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.
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.
Substantially longer battery life
350 shots longer battery life. CIPA is an independent, standard measurement that determines how many shots a camera can take before the battery dies.
Measurably faster maximum shutter speed
2x faster maximum shutter speed. A faster maximum shutter speed allows taking pictures of fast moving subjects without blur.
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.
Has a microphone in
A microphone port allows connecting external high-end or specialized microphones.
Sizably higher resolution (screen)
1228 k dots
1037 k dots
191 k dots higher resolution (screen). A higher screen resolution provides a sharper image, making it easier to review your photos.
Device is protected with extra seals to prevent failures due to any kind of weather.
Considerably faster flash X-sync
25% faster flash X-sync. Flash synchronization is defined as the firing of a photographic flash coinciding with the shutter admitting light to the image sensor. In general, faster flash sync speeds are better if the photographer needs to flash-fill subjects that are backlit and wants to avoid motion blur, or wants to increase depth of field by using a high aperture.
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.
