Understanding the Differences Between Four Thirds and Micro Four Thirds Systems
The Four Thirds and Micro Four Thirds systems are among the most popular sensor sizes and camera systems in modern photography. Both systems offer unique advantages, particularly in terms of portability, optics, and design. However, there are key differences between them that make each system suitable for different applications and photographer preferences. This article will explore the differences between the Two Thirds and Micro Four Thirds systems.
Introduction to Four Thirds System
The Four Thirds System was introduced by Olympus and Kodak in 2003. It utilizes a sensor size of 17.3x13 mm, and it has been a significant player in the DSLR camera market. The original Four Thirds system was designed to be the stepping stone to digital photography, and it quickly gained popularity for its favorable size-to-quality ratio and portability.
Introduction to Micro Four Thirds System
Following the success of the Four Thirds system, the manufacturers eventually transitioned to the Micro Four Thirds system in 2008. This system also features a 17.3x13 mm sensor but narrows the space between the lens flange and the sensor, allowing for a more compact design. This innovative shift enables the creation of ultra-compact mirrorless cameras that are highly portable and lightweight, further enhancing the system's appeal.
Key Differences Between Four Thirds and Micro Four Thirds Systems
The primary differences between the Two Thirds and Micro Four Thirds systems lie in their lens compatibility, design, and use cases.
Lens Compatibility
One of the most significant differences between the Two Thirds and Micro Four Thirds systems is their lens compatibility. Four Thirds system lenses can be used on Micro Four Thirds cameras with the help of an adapter. This compatibility is primarily due to the larger flange distance in the Four Thirds system. The flange distance in the original Four Thirds system is 28mm, whereas the Micro Four Thirds system's flange distance is significantly shorter at 18mm. Due to this difference, Micro Four Thirds lenses cannot be used on a Four Thirds camera, but they can be adapted for use on Micro Four Thirds cameras.
Design and Optics
The shorter flange to sensor distance in the Micro Four Thirds system allows for more creative optical designs. This design freedom means that lens manufacturers can create more compact and lightweight lenses that maintain high optical quality. The compactness of Micro Four Thirds cameras and lenses also makes them highly portable, which is an essential attribute for travel photographers and everyday users who prefer to carry a lightweight camera.
Use Cases and Applications
The Four Thirds system is often preferred for its balance between image quality and portability. It is a legacy system and offers a range of full-size lenses that are optimized for DSLR use. On the other hand, the Micro Four Thirds system is renowned for its ultra-compact design, making it an excellent choice for those who prioritize portability over some of the optical conveniences of a full-size DSLR.
Conclusion
In summary, while both the Four Thirds and Micro Four Thirds systems share the same sensor size, their differences in lens compatibility, design, and use cases highlight why each system has its own unique advantages. The Four Thirds system is ideal for photographers who prefer the features of a traditional DSLR, while the Micro Four Thirds system is perfect for those seeking the utmost in portability without compromising too much on image quality.
Whether you are using a Four Thirds or Micro Four Thirds system, understanding the specific attributes of each will help you choose the best camera for your photography needs and lifestyle.
