Micro Four Thirds system

The Olympus OM-D E-M1 is a Micro Four Thirds system camera.

The Micro Four Thirds system (MFT or M4/3) is a standard released by Olympus and Panasonic in 2008,[1] for the design and development of mirrorless interchangeable lens digital cameras, camcorders and lenses.[2] Camera bodies are available from Blackmagic, DJI, JVC, Kodak, Olympus, Panasonic, and Xiaomi, with lenses produced by Cosina Voigtländer, DJI, Kowa, Kodak, Mitakon, Olympus, Panasonic, Samyang, Sigma, SLR Magic, Tamron, Tokina, Veydra, and Xiaomi, among others.

MFT shares the original image sensor size and specification with the Four Thirds system, designed for DSLRs. Unlike Four Thirds, the MFT system design specification does not provide space for a mirror box and a pentaprism, which facilitates smaller body designs and a shorter flange focal distance, and hence smaller lenses. With adapters, most lenses can be used on MFT camera bodies, including those produced by Canon and Nikon, and lenses produced for cinema (eg, PL mount or C mount).

Sensor size and aspect ratio

The image sensor of Four Thirds and MFT measures 18 mm × 13.5 mm (22.5 mm diagonal), with an imaging area of 17.3 mm × 13.0 mm (21.6 mm diagonal), comparable to the frame size of 110 film.[3] Its area, ca. 220 mm², is approximately 30% less than the quasi-APS-C sensors used in other manufacturers' DSLRs, yet is around 9 times larger than the 1/2.3" sensors typically used in compact digital cameras.

The Four Thirds system uses a 4:3 image aspect ratio, like compact digital cameras. In comparison, DSLRs usually adhere to the 3:2 aspect ratio of the traditional 35 mm format. Thus, "Four Thirds" refers to both the size of the image and the aspect ratio of the sensor.[4] However, the chip diagonal is a half inch shorter than 4/3 of an inch. The 4/3 inch designation for this size of sensor dates back to the 1950s and vidicon tubes, when the external diameter of the camera tube was measured, not the active area.

The MFT design standard also specifies multiple aspect ratios: 4:3, 3:2, 16:9 (the native HD video format specification), and 1:1 (a square format). With the exception of two MFT cameras,[5][6] all MFT cameras record in a native 4:3 format image aspect ratio, and through cropping of the 4:3 image, can record in 16:9, 3:2 and 1:1 formats.

In addition, all current Micro Four Thirds cameras have sensor dust removal technologies.

Lens mount

The MFT system design specifies a bayonet type lens mount with a flange focal distance of slightly under 20 mm. By avoiding internal mirrors, the MFT standard allows a much thinner camera body. Viewing is achieved on all models by live view electronic displays with LCD screens. In addition some models feature a built-in electronic viewfinder (EVF) while others may offer optional detachable electronic viewfinders, or even as an option an independent optical viewfinder typically matched to a particular non-zoom prime lens. The flange diameter is about 38 mm, 6 mm less than that of the Four Thirds system. Electrically, MFT uses an 11-contact connector between lens and camera, adding to the nine contacts in the Four Thirds system design specification. Olympus claims full backward compatibility for many of its existing Four Thirds lenses on MFT bodies, using a purpose built adapter with both mechanical and electrical interfaces.[7]

The shallow but wide MFT lens mount also allows the use of existing lenses including Leica M, Leica R, and Olympus OM system lenses, via Panasonic and Olympus adapters. Aftermarket adapters include Leica Screw Mount, Contax G, C mount, Arri PL mount, Canon, Nikon, and Pentax, among others.[8] In fact, almost any still camera, movie or video camera interchangeable lens that has a flange focal distance greater than or marginally less than 20 mm can often be used on MFT bodies via an adapter. While MFT cameras can only use many of these "legacy" lenses with manual focus and aperture control mode, hundreds of lenses are available, even those designed for cameras no longer in production.

Autofocus design

MFT cameras usually use contrast-detection autofocus (CDAF), a common autofocus system for mirrorless compact or "point-and-shoot". By comparison, DSLRs use phase-detection autofocus (PDAF). The use of separate PDAF sensors has been favored in DSLR systems because of mirror box and pentaprism design, along with better performance for fast-moving subjects.

The (non-Micro) Four Thirds system design standard specifies a 40 mm flange focal length distance, which allowed for using a single lens reflex design, with mirror box and pentaprism. Four Thirds DSLR cameras designed by Olympus and Panasonic initially used exclusively PDAF focusing systems. Olympus then introduced the first live view DSLR camera, which incorporated both traditional DSLR phase focus and also optional contrast detection focus. As a result, newer Four Thirds system lenses were designed both for PDAF and contrast focus. Several of the Four Thirds lenses focus on Micro Four Thirds proficiently when an electrically compatible adapter is used on the Micro Four Thirds cameras, and they focus on Micro Four Thirds cameras much quicker than earlier generation Four Thirds lenses can.

Some MFT cameras, such as the OM-D E-M1 and E-M1 Mark II incorporate phase-detection hardware on the sensor to support legacy lenses. These camera bodies perform better with legacy lenses (eg, focus performance of the 150mm f/2 and 300mm f/2.8 lenses are as quick and accurate as a native Four Thirds body).

Comparison with other systems

For comparison of the original Four Thirds with competing DSLR system see Four Thirds system#Advantages, disadvantages and other considerations

Compared to most digital compact cameras and many bridge cameras, MFT cameras have better, larger sensors, and interchangeable lenses. Some lenses feature wider apertures than those available on many compacts, providing more control over depth-of-field and yielding greater creative possibilities. However, Micro Four Thirds cameras also tend to be larger, heavier and more expensive than compact cameras.

Compared to most digital SLRs, Micro Four Thirds cameras are smaller and lighter. However, the smaller sensors may produce inferior image quality in low light conditions, and may lack features such as viewfinders and built-in flash units. Micro Four Thirds cameras sometimes afford greater depth-of-field than SLRs depending on the lens used.

The much shorter flange focal distance enabled by the removal of the mirror allows normal and wide angle lenses to be significantly smaller because they do not have to use strongly retrofocal designs.

The Four Thirds sensor format used in MFT cameras is equivalent to a 2.0 crop factor when compared to a 35 mm film (full frame) camera. This means that the field of view of a MFT lens is the same as a full frame lens with twice the focal length. For example, a 50 mm lens on a MFT body would have a field of view equivalent to a 100 mm lens on a full frame camera. For this reason, MFT lenses can be smaller and lighter because to achieve the equivalent 35 mm film camera field of view, the MFT focal length is much shorter. See the table of lenses below to understand the differences better. For comparison, typical DSLR sensors, such as Canon's APS-C sensors, have a crop factor of 1.6.

Equivalents

This section gives a brief introduction to the subject of "Equivalence" in photography. Equivalent images are made by photographing the same angle of view, with the same depth of field and the same Angular resolution due to diffraction limitation (which requires different f-stops on different focal length lenses), the same motion blur (requires the same shutter speed), therefore the ISO setting must differ to compensate for the f-stop difference. The use of this is only to let us compare the effectiveness of the sensors given the same amount of light hitting them. In normal photography with any one camera, equivalence is not necessarily an issue: there are several lenses faster than f/2.4 for micro four thirds (see the tables under Fixed Focal Length Lenses, below), and there are certainly many lenses faster then f/4.8 for full frame and no one hesitates to use them even though they can have shallower depth of field than a Nikon 1 at f/1.7, in fact that can be seen as advantageous, but it has to be taken into consideration that a further aspect of image resolution is limitation by optical aberration, which can be compensated the better the smaller the focal lengths of a lens is.[9] Lenses designed for mirrorless camera systems such as Nikon 1 or Micro Four Thirds often use image-space telecentric lens designs,[10] which reduce shading and therefore light loss and blurring at the microlenses of the image sensor.[11] Furthermore, in low light conditions by using low f-numbers a too shallow depth of field can lead to less satisfying image results, especially in videography, when the object taken by the camera or the camera itself are moving. For those interested in producing equivalent images, read on.

Equivalent focal lengths are given, if the angle of view is identical.[12]

The depth of field is identical, if angle of view and absolute aperture width are identical. Also the relative diameters of the Airy disks representing the limitation by diffraction are identical. Therefore, the equivalent f-numbers are varying.[13]

In this case, i.e. with the same luminous flux within the lens, the illuminance quadracially decreases and the luminous intensity quadratically increases with the image size. Therefore, all systems detect the same luminances and the same exposure values in the image plane, and as a consequence of this the equivalent exposure indexes are different in order to get the identical shutter speeds (i.e. exposure times) with the same levels of motion blur and image stabilisation.[14]

The following table exemplarily shows a few identical image parameters for some popular image sensor classes compared to Micro Four Thirds:[15]

Advantages of Micro Four Thirds over DSLR cameras

Micro Four Thirds has several advantages over larger format cameras and lenses:

Advantages of the electronic viewfinder

Though many DSLRs also have "live view" functionality, these function relatively poorly compared to a Micro Four Thirds electronic viewfinder (EVF), which has the following advantages:

Olympus and Panasonic approached the implementation of electronic viewfinders in two ways: the built-in EVF, and the optional hotshoe add-on EVF.

Until the introduction of the OM-D E-M5 in February, 2012, none of the Olympus designs included a built-in EVF. Olympus has four available add-on hotshoe viewfinders. The Olympus VF-1 is an optical viewfinder with an angle of view of 65 degrees, equivalent to the 17mm pancake lens field of view, and was designed primarily for the EP-1. Olympus has since introduced the high resolution VF-2 EVF,[17] and a newer, less expensive, slightly lower resolution VF-3[18] for use in all its MFT cameras after the Olympus EP-1. These EVF's not only slip into the accessory hotshoe, but also plug into a dedicated proprietary port for power and communication with Olympus cameras only. Both the VF-2 and VF-3 may also be used on high-end Olympus compact point and shoot cameras such as the Olympus XZ-1. Olympus announced the VF-4 in May 2013, along with the fourth generation PEN flagship, the E-P5.

As of mid-2011, Panasonic G and GH series cameras have built in EVF's, while two of the three GF models are able to use the add-on LVF1[19] hotshoe EVF. The LVF1 must also plug into a proprietary port built into the camera for power and communication. This proprietary port and the accessory is omitted in the Panasonic Lumix DMC-GF3 design. Similar to Olympus, the LVF1 is usable on high-end Panasonic compact point and shoot cameras, such as the Panasonic Lumix DMC-LX5.

As of June 2012, Olympus, Panasonic, Cosina Voigtländer, Carl Zeiss AG, Jos. Schneider Optische Werke GmbH, Komamura Corporation, Sigma Corporation, Tamron,[25] Astrodesign,[25] Yasuhara,[26] and Blackmagic Design[27] have a commitment to the Micro Four Thirds system.

The first Micro Four Thirds system camera was Panasonic Lumix DMC-G1, which was launched in Japan in October 2008.[28] In April 2009, Panasonic Lumix DMC-GH1 with HD video recording added to it.[29] The first Olympus model, the Olympus PEN E-P1, was shipped in July 2009.

In August 2013 SVS Vistek GmbH in Seefeld, Germany introduced the first high-speed industrial MFT lens mount camera using 4/3" sensors from Truesense Imaging, Inc (formally Kodak sensors), now part of ON Semiconductor. Their Evo "Tracer" cameras range from 1 megapixels at 147 frames per second (fps) to 8 megapixels at 22 fps.

In 2014, JK Imaging Ltd., which holds the Kodak brand, released its first Micro Four Thirds camera, the Kodak Pixpro S-1;[30] several lenses and niche camera makers have products made for the standard. In 2015, DJI provided its drone with optional MFT cameras. Both cameras can capture 16MP stills and up to 4K/30fps video with an option of 4 interchangeable lenses ranging from 12mm to 17mm.[31] In 2016, Xiaomi introduced the YI M1, a 20MP MFT camera with 4K video capability.[32]

Blackmagic design has a range of cameras made for cinematography.

Micro Four Thirds lenses

Nocticron 42.5 mm f/1.2

Because the flange focal distance of Micro Four Thirds cameras are shorter than DSLRs, most lenses are smaller and cheaper.

Of particular interest in illustrating this fact are the Panasonic 7–14 mm ultra-wide angle (equivalent to 14–28 mm in the 35 mm film format) and the Olympus M.Zuiko Digital ED 9–18 mm ultra wide-angle lens (equivalent to an 18–36 mm zoom lens in the 35 mm film format). Furthermore, the lens designers could develop the world's fastest fisheye lens with autofocus, the Olympus ED 8 mm f/1.8.

On the telephoto end, the Panasonic 100–300 mm or the Leica DG 100-400 mm as well as the Olympus 75–300 mm zooms show how small and light extreme telephotos can be made. The 400 mm focal length in Micro Four Thirds is equivalent to 800 mm focal length in more traditional full frame cameras.

When compared to a full frame camera lens providing a similar angle of view, rather than weighing a few kilograms (several pounds) and generally having a length of over 60 cm (2 ft) end to end, the optically stabilized Panasonic Lumix G Vario 100–300 mm lens weighs just 520 grams (18.3 oz), is only 126 mm (5.0 in) long, and uses a relatively petite 67 mm filter size.[64] As a point of comparison, the Nikon 600 mm f5.6 telephoto weighs 3600 grams (7.9 lb), is 516.5 mm (20.3 in) in length and uses a custom 122 mm filter.[65]

Image stabilization approaches

Olympus and Panasonic have both produced cameras with sensor-based stabilization, and lenses with stabilization. However, the lens stabilization will only work together with body stabilization for cameras of the same brand. Before 2013, Olympus and Panasonic approached image stabilization (IS) differently. Olympus used sensor-shift image stabilization only, which it calls IBIS (In-Body Image Stabilization), a feature included all of its cameras. Until 2013, Panasonic used lens-based stabilization only, called Mega OIS or Power OIS. These stabilize the image by shifting a small optical block within the lens.

Telephoto zoom lens Leica DG 100-400 mm

In 2013, Panasonic began including sensor-based stabilization in its cameras, beginning with the Lumix DMC-GX7. Panasonic called the combination of lens and body stabilization "Dual IS," and this function won an award of the European Imaging and Sound Association (EISA) in the category Photo Innovation 2016-2017.[66] In 2016, Olympus added lens-based stabilization to the M. Zuiko 300mm f/4.0 Pro telephoto prime lens and the M. Zuiko 12-100mm f/4.0 IS Pro lens.

Panasonic claims that OIS is more accurate because the stabilization system can be designed for the particular optical characteristics of each lens. A disadvantage of this approach is that the OIS motor and shift mechanism must be built into each lens, making lenses more expensive than comparable non-OIS lenses. Of all Panasonic lenses only few with short focal lengths, and therefore wide angles of view and low susceptibility to image shaking, are not image stabilized, including the 8 mm fisheye, 7–14 mm wide angle zoom, 14 mm prime, the 15 mm prime, and the 20 mm prime.

The advantage of in-body IS is that even unstabilized lenses can make use of the in-body stabilization. This has created in Micro Four Thirds cameras by many hobbyists, especially amongst users of traditional Leica or Voigtländer rangefinder cameras.

Lens compactness and mount adaptability

Since most Micro Four Thirds lenses have neither a mechanical focusing ring nor an aperture ring, adapting these lenses for other camera mounts is impossible or compromised. A variety of companies manufacture adapters to use lenses from nearly any legacy lens mount[8] (such lenses, of course, support no automatic functions.) For the Four Third lenses that can be mounted on MFT bodies, see Four Thirds system lenses. For the Four Third lenses that support AF, see the Olympus website.[67] For those that support fast AF (Imager AF), see the Olympus website.[68]
