The Micro Four Thirds Sensor
Micro Four Thirds uses a 17.3 × 13 mm sensor with a 2× crop factor. This guide covers sensor size, what the crop factor means in practice, how M43 compares to APS-C and full frame, and every sensor generation from 12MP to 25MP.
Read guide →What Is Micro Four Thirds? A Beginner's Guide
Micro Four Thirds is a mirrorless camera system built around a 17.3 x 13 mm sensor and a shared lens mount used by Panasonic, OM System, and others. This guide explains what that means in practice, without the jargon.
Read guide →Micro Four Thirds vs Full Frame
Full frame wins on noise and background blur. M43 wins on size, weight, cost, and telephoto reach. This guide covers every meaningful difference so you can choose the right system for how you actually shoot.
Read guide →Depth of Field on Micro Four Thirds
Depth of field is the band of your scene that looks acceptably sharp. It is the single most misunderstood part of moving to or from Micro Four Thirds, because the smaller sensor changes it in a way that is easy to state wrong. This guide explains what actually happens, why, and how to use it, including hyperfocal distance for landscapes.
Read guide →Teleconverters on Micro Four Thirds
A teleconverter sits between your camera and a compatible lens and multiplies the focal length, giving more reach without a whole new lens. On Micro Four Thirds, where reach is already a strength, a teleconverter pushes a telephoto setup into extreme territory. This guide covers how they work, what they cost you in light and sharpness, and which lenses accept them.
Read guide →Micro Four Thirds for Astrophotography
Micro Four Thirds is often dismissed for night photography because of its smaller sensor. The truth is more interesting. M43 collects less light per frame than full frame, but the system has fast wide lenses, strong stabilisation, and OM System computational features built specifically for the night sky. With the right technique it produces excellent Milky Way images.
Read guide →Micro Four Thirds for Street Photography
M43 is a strong street photography system because the bodies are small, the fast primes are affordable, and the system is discrete enough to use without drawing attention. The format's size advantage is most obvious when you compare it to a full-frame kit doing the same job.
Read guide →Micro Four Thirds for Travel Photography
A weather-sealed M43 body and one versatile zoom lens can cover 24-200mm equivalent at under 1kg combined. The format's compact size, widespread IBIS, and flexible lens options make it a practical choice for photographers who want a capable interchangeable lens system without a dedicated camera bag.

Most Micro Four Thirds cameras come with a kit zoom. For many people that is enough to start. But a fast prime lens will show you what the system is really capable of. This guide helps you decide what to add first.
Read guide →Are Four Thirds Lenses Compatible with Micro Four Thirds?
Four Thirds lenses can be used on Micro Four Thirds cameras with the MMF-3 or similar adapter, but autofocus is slower and contrast-detect only. This guide explains what works, what does not, and when it makes sense.
Read guide →How to Choose a Micro Four Thirds Camera
There are over two dozen active Micro Four Thirds bodies on the market. Most beginners overbuy or underbuy. This guide helps you cut through the specs and find what actually matters for how you shoot.
Read guide →How to Update Firmware on OM System and Olympus Cameras
OM System and Olympus cameras support firmware updates via the OI.Share mobile app (recommended for OM-1, OM-1 Mark II, OM-5, E-M1 Mark III) or via OM Workspace desktop software (required for older bodies). Both methods are straightforward but require a fully charged battery and should not be interrupted.
Read guide →How to Update Firmware on Panasonic Lumix Cameras
Panasonic Lumix firmware updates are done via SD card. You download the firmware file from Panasonic's support site, copy it to the root of a formatted SD card, and run the update from the camera's Setup menu. The process takes 2-3 minutes and must not be interrupted.

The 'M43 is dead' claim resurfaces every year. The actual release record from 2023 to 2026 tells a different story. This guide looks at what has shipped, what is missing, and what that means for buyers.
Read guide →Micro Four Thirds for Bird and Wildlife Photography
M43's 2x crop factor gives you 600mm equivalent reach from a 300mm lens. Paired with subject-tracking AF and compact telephoto glass, it is one of the most practical systems for bird and wildlife photography without the weight and cost of full-frame telephoto rigs.
Read guide →Micro Four Thirds for Macro Photography
M43 has five dedicated macro lenses covering 30mm to 90mm and a strong focus stacking implementation on OM System bodies. The smaller sensor gives more depth of field at equivalent magnification, which helps with the razor-thin focus planes typical of close-up work.
Read guide →How to Check the Shutter Count on Olympus and OM System Cameras
Olympus and OM System cameras store the shutter count internally, not in image EXIF data. You access it through a hidden service menu using a specific button sequence. The steps are the same across most OM-D and OM System bodies.
Read guide →How to Check the Shutter Count on Panasonic Lumix Cameras
Panasonic does not embed shutter count in EXIF data, so online tools cannot read it from your image files. The count is stored internally and accessed through a hidden service menu - or in recent firmware, through the standard camera menu.

Both brands share the same lens mount and sensor size, but they have different strengths. Panasonic leans toward video; OM System leans toward stills and outdoor shooting. This guide breaks down where each brand wins.
Read guide →What Is Dual IS on Micro Four Thirds Cameras?
Dual IS coordinates lens optical stabilisation and body IBIS so both systems work together rather than independently. It is specific to Panasonic M43 bodies and compatible lenses. This guide explains the difference it makes and how to check your combination.
Read guide →Micro Four Thirds vs APS-C
The sensor gap between M43 and APS-C is 1.6× by area, smaller than the M43 vs full-frame gap. This guide covers noise, depth of field, lens ecosystems, telephoto reach, and who each system suits.
