23 Reasons why Nikon D4 is better

Comparing Nikon D4 vs Olympus OM-D E-M5

1.Somewhat more megapixels (photo)
16.2MPvs 16.1MP (Olympus OM-D E-M5)
2.Considerably larger sensor
36 x 23.9mmvs 17.3 x 13mm (Olympus OM-D E-M5)
The larger the sensor the more light the sensor captures yielding in better image quality.
3.Significantly more focus points
51vs 35 (Olympus OM-D E-M5)

4.Measurably faster shooting at highest resolution with AF as JPEG format
11fpsvs 9fps (Olympus OM-D E-M5)
Fast continuous shooting is useful for catching action shots.
5.Faster video autofocus due to a phase detection autofocus when shooting movies
Yesvs No (Olympus OM-D E-M5)
A phase detection autofocus is much faster than a contrast detection autofocus and allows sharper movies.
6.Distinctly faster maximum shutter speed
0.000125svs 0.00025s (Olympus OM-D E-M5)
A faster maximum shutter speed allows taking pictures of fast moving subjects without blur.
7.Has a 24p cinema mode
Yesvs No (Olympus OM-D E-M5)
24p is a video format (24 frames per second) traditionally used in cinema. Nowadays, it is used to create film-like motion characteristics.
8.Higher pixel density
442ppivs 375ppi (Olympus OM-D E-M5)
9.Has a built-in HDR mode
Yesvs No (Olympus OM-D E-M5)
It can automatically shoot pictures with a higher dynamic range (HDR).
10.Appreciably more battery power
2000mAhvs 1220mAh (Olympus OM-D E-M5)
11.Notably higher resolution (screen)
921k dotsvs 610k dots (Olympus OM-D E-M5)
A higher screen resolution provides a sharper image, making it easier to review your photos.
12.Is dustproof and water resistant
Yesvs No (Olympus OM-D E-M5)
Dustproof / water resistant at depth equal to or greater than 1m.
13.Substantially higher resolution

14.Has a built-in focus motor
Yesvs No (Olympus OM-D E-M5)
The focus motor moves the lens in order to autofocus. For system cameras, having a focus motor in the camera's body allows you to use a wide range of lenses, including lenses which do not have their own focus motor. For compact cameras, a focus motor is usually built-in.
15.Slightly bigger screen size
3.2"vs 3" (Olympus OM-D E-M5)
The bigger the screen size is, the better the user experience.
16.Has GPS
Yesvs No (Olympus OM-D E-M5)
GPS enables global positioning, useful in map, geo-tagging or navigation apps.
17.Faster photo autofocus due to a phase detection autofocus when shooting pictures
Yesvs No (Olympus OM-D E-M5)
A phase detection autofocus is much faster than a contrast detection autofocus and allows sharper images.
18.Significantly less shutter lag
0.208svs 0.277s (Olympus OM-D E-M5)
The amount of time it takes the camera to take a photo, without having to focus.
19.Can be controlled remotely
Yesvs No (Olympus OM-D E-M5)
A remote control allows you to control the device remotely. The remote control can be included or optional.

It takes less time for the camera to turn on and take a first picture.
21.Has dual card slots
Yesvs No (Olympus OM-D E-M5)
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.
22.Every pixel has three subpixels
Yesvs No (Olympus OM-D E-M5)
The device has a display with three full subpixels per pixel, resulting in a sharp and crisp picture. Pixels in some displays (like AMOLED) share one subpixel to preserve space. This can result in a less crisp, slightly blurred image.

Yesvs No (Nikon D4)
AVCHD (Advanced Video Coding High Definition) is a file-based format for the digital recording and playback of high-definition video. It's a standard popular among professional cameras and camcorders.
11.Distinctly longer exposure time
60svs 30s (Nikon D4)
