The OM-D E-M1 MARK II is the new flagship from Olympus. The new camera has a 20.4 megapixel Live MOS sensor, more than its predecessor. Olympus are promoting the benefits of its speed and compact size.
The digital sensor is still the slightly quirky four thirds format and is considerably smaller than a full frame sensor, with a crop factor of two. The smaller sensor and mirrorless design allows Olympus to produce a compact camera body and lenses making it easier to carry. While the camera is classified as mirrorless, it does have an electronic viewfinder. This has advantages when photographing with telephoto lenses or in low light conditions of being able to hold the camera securely and minimise camera shake.
The Olympus OM-D E-M1 MARK II has the five-axis sensor shift Image Stabilisation system to reduce the effect of camera shake. Some of the new Zuiko telephoto lenses also have Image Stabilisation in the lens. Olympus say they work with in conjunction with the system in the camera body to produce even greater stabilisation.
Fast autofocus for mirrorless cameras was an issue due to the lack of space in the camera body. Normal DSLRs use part the mirror box space for an Autofocus sensor array. In a mirrorless camera, especially the Olympus where the aim is small size, there is nowhere to put one. The Olympus answer is to include the AF sensors in the image sensor chip.
In the Olympus OM-D E-M1 MARK II there are 121 points of cross-type on-chip phase detection and contrast detection for the AF system.
In the DxOMark lab the new Olympus acquitted itself well against a leading APS-C camera, the Nikon D7200, with comparable noise performance. Naturally, against the much larger sensor on a full frame DSLR it has slightly more digital noise, but horribly so.
In continuous shooting mode the OM-D E-M1 MARK II uses the electronic shutter to capture full-resolution RAW images up to 60 frames per second with AF and AE locked, and up to 18 frames per second with continuous AF and AE tracking. This underlines the continual advances in camera processing power and speed in reading the image information from the digital sensor.
This mode further illustrates the processing power of the OM-D E-M1 MARK II. In this mode when the shutter button is half depressed the camera starts taking a continuous stream of photos and stores them in a temporary 14 shot buffer. When the shutter is fully pressed that photo and the last 14 images are permanently recorded. So you can take the photo just after the event happened, great for capturing unexpected action photos.
This combines two of the main strengths of the Olympus OM-D E-M1 MARK II, the on board processing power and the in-camera Image Stabilisation system. A higher resolution image is created by using the 5-Axis Image Stabilisation System to precisely shift the sensor in half-pixel increments while capturing a total of eight shots. The camera then automatically combines the shots into a single 50-megapixel equivalent ultra-high resolution image.
In the stacking mode the camera takes 8 shots at different focus points and combines them into one image with exceptional depth of field. Ideal for macro photography, although only some Ziuko lenses are compatible with this function. Focus bracketing is similar except the individual shots are saved for external processing.
Lenses compatible with Focus Stacking Mode:
M.ZUIKO Digital ED 7-14mm f2.8 PRO,
M.ZUIKO Digital ED 8mm f1.8 Fisheye PRO,
M.ZUIKO Digital ED 12-40mm f2.8 PRO,
M.ZUIKO Digital ED 40-150mm f2.8 PRO,
M.ZUIKO Digital ED 300mm f4.0 IS PRO,
M.ZUIKO Digital ED 30mm f3.5 Macro
M.ZUIKO Digital ED 60mm f2.8 Macro.
Not all DSLRs have this high quality video capability, they mostly make do with HD video. So if you want a compact DSLR style camera with professional standard video then the Olympus is a contender.
The major drawback for the Olympus OM-D E-M1 MARK II is the odd size digital sensor. The four thirds sensor is half the size of the increasingly common full frame sensors in other top of the range DSLR format cameras. Olympus have compensated by packing a load of technology into a compact easy to carry package.
