Micro Four Thirds system

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

The Micro Four Thirds system (MFT) is a standard created by Olympus and Panasonic, and announced on August 5, 2008,[1] for the design and development of mirrorless interchangeable lens digital cameras, camcorders and lenses.[2] In 2014, JK Imaging Ltd., which holds the Kodak brand, released its first Micro Four Thirds camera, the Kodak Pixpro S-1;[3] 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.[4]

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. Virtually any lens can be used on MFT camera bodies, as long as an adapter exists. For instance, Four Third lenses can be used with auto focus using the adapters designed by Olympus and Panasonic.

Sensor size and aspect ratio

The image sensor of Four Thirds and MFT is commonly referred to as a 4/3" type or 4/3 type sensor (inch-based sizing system is derived from now obsolete video camera tubes). The sensor 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.[5] 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 1/2.5" sensors typically used in compact digital cameras.

The Four Thirds system uses a 4:3 image aspect ratio, in common with other compact digital cameras but unlike quasi-APS-C or 24×36 mm DSLRs, which usually adhere to the 3:2 aspect ratio of the traditional 35 mm format. Thus the "Four Thirds" refers to both the size of the image and the aspect ratio of the sensor.[6] Note that actual size of the chip is considerably less than 4/3 of an inch, the length of the diagonal being only 22.5 mm. 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 calls for being able to record multiple formats, 4:3, 3:2 (traditional DSLR formats with origins with 35 mm film still cameras), 16:9 (the native HD video format specification), and 1:1 (a square format). With the exception of two MFT cameras, 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. This multiple recording format flexibility is a MFT system design standard, which also incorporates seamless integration of HD video recording in the same camera body.

The 2009 introduction of the Panasonic Lumix DMC-GH1 camera extends the 4:3 format image aspect ratio recording capabilities to native 16:9 and 3:2 image aspect ratio formats, rather than crops of a native 4:3 image. The GH1 uses a bigger sensor matrix that uses the full diagonal of the image circle in all three formats. This is called multi-aspect capability. To date, the multi-aspect sensor is common only to the Panasonic GH1[7] and its successor the Panasonic Lumix DMC-GH2.[8]

In addition, all current Micro Four Thirds cameras have sensor dust removal technologies, but this is not exclusive to the format.

Lens mount

The MFT system design specifies a new bayonet type lens mount with a flange focal distance of slightly under 20 mm – half as deep as the Four Thirds system design. 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 (though when using FT lenses, the speed of the autofocus may be slower in certain conditions than when using dedicated Four Thirds body, because of differences in type of the AF system).

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. One example is the Panasonic Lumix 14-45mm lens. Aftermarket adapters include Leica Screw Mount, Contax G, C mount, Arri PL mount, Canon, Nikon, and Pentax, among others.[9] 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 that survive for cameras no longer in production.

Autofocus design

The MFT system design specifies the use of contrast-detection autofocus (CDAF), which is a common autofocus system for compact or "point-and-shoot". By comparison, virtually all DSLRs use a different autofocus system known as phase-detection autofocus (PDAF). The use of separate PDAF sensors has long 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 latter Four Thirds lenses focus on Micro Four Thirds proficiently when an electrically compatible adapter is used on the Olympus and the later Panasonic Micro Four Thirds cameras, and they focus on Micro Four Thirds cameras much quicker than earlier generation Four Thirds lenses can.

At the announcement of the MFT system design standard it was suggested that the powerful focusing motors required for contrast-detection autofocus by compact cameras and MFT may not operate properly on at least some of the existing Four Thirds lenses designed for phase-detection autofocus.[10]

Many PDAF Four Thirds system lenses, when using adapters with proper electrical connections on Micro Four Thirds cameras, do focus much more slowly than "native" designed MFT lenses. Some Four Thirds bodies do not focus as quickly as others, or as accurately as does contrast focus. This is a downside of phase focus, which can shift focus to the front or behind the calculated focus position for each lens. Micro Four Thirds also focus Four Thirds lenses faster than a Four Thirds camera focuses using the Four Thirds "Live View" focus. Most Four Thirds lenses still work on Micro Four Thirds, and the relative speed depends on the camera model and lens. Overall, native Micro Four Thirds lenses focus much faster than the majority of Four Thirds lenses.

An advantage to the newly introduced MFT system designed cameras is the already-existing family of very high quality, large aperture, automatic exposure, autofocusing, and sometimes even optical image stabilized Four Thirds lenses made by Olympus, Panasonic and Leica.

Olympus claims their Pen cameras (the E-P5, the smaller E-PL5, and its less expensive "mini" version E-PM2) are the fastest focusing removable lens cameras, including those that use phase technology (DSLR cameras). Comparative tests and the basis for all the speed improvements and whether the technology can track like a phase focus designed for sport applications are not yet known.

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, Micro Four Thirds cameras may 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, they also have smaller sensors (and therefore may have inferior image quality, especially in low light conditions), and often 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. They are not necessarily less expensive than SLRs.

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 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. Practically speaking, this means that 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. Said another way, normal lenses on MFT cameras would be only 25 mm. 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. Typical DSLR sensors such as Canon's APS-C sensors, have a crop factor of 1.6, compared to full frame's (35 mm) 1.0, and Four Thirds 2.0.

Equivalents

Equivalent focal lengths are given, if the angle of view is identical.[11]

The depth of field is identical, if angle of view and absolute aperture size are identical. At the same image resolution also the relative diameters of the Airy disks are identical. Therefore, the equivalent f-numbers are varying.[12]

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).[13]

The following table exemplarily shows a few identical image parameters for some popular image sensor classes compared to Micro Four Thirds:[14]

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,[16] and a newer, less expensive, slightly lower resolution VF-3[17] 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[18] 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.

Micro Four Thirds system cameras

The Olympus E-PL5 was announced on 17 September 2012 at the photokina 2012 trade show

As of Jun 2012, Olympus, Panasonic, Cosina Voigtländer, Carl Zeiss AG, Jos. Schneider Optische Werke GmbH, Komamura Corporation, Sigma Corporation, Tamron,[24] Astrodesign,[24] Yasuhara,[25] and Blackmagic Design[26] 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.[27] In April 2009, Panasonic Lumix DMC-GH1 with HD video recording added to it.[28]

The first Olympus model, the Olympus PEN E-P1, was shipped in July 2009. In January 2014, JK Imaging Ltd. launched its Kodak-branded model S-1.

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.

Blackmagic design has a range of cameras made for cinematography.

Micro Four Thirds lenses

A promise of the Micro Four Thirds standard is reduced lens size and weight. The reduced flange focal distance of Micro Four Thirds lets most lenses be made significantly smaller and cheaper than for a traditional DSLR, because the retrofocus optical schemes can be avoided or made less extreme. 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). On the telephoto end, the Panasonic 100–300 mm and Olympus 75–300 mm zooms show how small and light extreme telephotos can be made. The 300 mm focal length in Micro Four Thirds is equivalent to 600 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 an 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.[58] 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.[59]

Further, both Panasonic and Olympus manufacture an adapter[60] to enable use of any Four Thirds lenses on Micro Four Thirds cameras. While many Four Thirds lenses accept firmware updates to enable contrast autofocusing, some are slow to autofocus, and some others are manual-focus-only.

Image stabilization approaches

Olympus and Panasonic approach image stabilization (IS) differently. Olympus uses sensor-shift image stabilization, which it calls IBIS (In-Body Image Stabilization). IBIS stabilizes the image by shifting of the entire sensor. Panasonic uses lens-based stabilization, which it calls Mega OIS. Mega OIS stabilizes the image by shifting a small optical block within the lens. In August 2013 Panasonic also introduced a camera (Lumix DMC-GX7) featuring a built-in IBIS.

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 each lens physically larger, heavier and more expensive than a comparable non-OIS lens. As of mid-2011, of the available and announced Panasonic lenses, the 8 mm fisheye, 7–14 mm wide angle zoom, 14 mm prime, and 20 mm prime are not image stabilized.

Whilst none of the Olympus lenses have built-in IS, all Olympus Micro Four Thirds cameras have in-camera IS, and therefore all Olympus M.Zuiko Digital lenses benefit from the camera's stabilization system. The advantage with Olympus' in-body IS is that Olympus lenses are smaller and lighter than comparable Panasonic lenses, and even vintage manual focus lenses can make use of the in-body stabilization when used with an appropriate mount adapter. This latter fact has added to interest in Micro Four Thirds cameras by many hobbyists, especially amongst users of traditional Leica or Voigtländer rangefinder cameras. Olympus introduced in 2012 a new leap forward IBIS technology: Olympus "5 Axis" IBIS system, initially only available on "OM-D" generation Olympus cameras.

Lens compactness and mount adaptability

Since most Micro-Four-Thirds lenses have neither a mechanical focussing 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[9] (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.[61] For those that support fast AF (Imager AF), see.[62]

As of November 2013, the following Micro Four Thirds system lenses, which can be used by all MFT camera bodies, except as noted, have been released or announced with availability within 3 months of announcement:
