Micro four thirds
The micro four thirds sensor has emerged as a topic of controversy within the modern digital camera landscape. Slightly larger than the one-inch sensor, it boasts a crop factor of approximately 2x. Originally developed by Olympus and Kodak as the Four Thirds system, it underwent further enhancements by Olympus and Panasonic, resulting in a more compact and lightweight internal mechanism, subsequently renamed as Micro Four Thirds.
During its initial release, the micro four thirds sensor gained significant popularity, attracting a few third-party brands to adopt the system. However, over time, some of these brands either ceased producing cameras for this system or transitioned to other sensor sizes as alternatives emerged.
The controversy surrounding micro four thirds stems from the fact that many cameras employing this sensor are priced similarly or even higher than those featuring larger sensors such as APS-C and Full Frame. Additionally, prominent third-party lens manufacturers like Tamron and Sigma allocate fewer resources to developing lenses for micro four thirds compared to APS-C and Full Frame systems. This factor makes micro four thirds less appealing to those considering an interchangeable lens camera system for the first time.
Nevertheless, considering the second-hand market, micro four thirds lenses and cameras offer competitive prices, often available for half or even a quarter of the cost of their APS-C and Full Frame equivalents. This makes micro four thirds an ideal system for individuals open to purchasing camera equipment from reputable second-hand dealers or who possess the knowledge to inspect used camera gear effectively.
One advantage of the micro four thirds sensor is its effective sensor-based image stabilization, resulting in sharper images, particularly in low-light situations, without the need for a stabilized lens. When it comes to 4K recording, micro four thirds sensors exhibit slower heat build-up compared to APS-C and Full Frame sensors, enabling longer continuous recording without requiring frequent cooling breaks.
Regarding lens compatibility, as long as a lens is designed for Micro Four Thirds, it can be interchanged between brands while maintaining at least 90% of its functionality. This level of compatibility is not guaranteed in APS-C, Full Frame, or Medium Format systems without the use of adapters.
Other advantages of micro four thirds cameras include their lighter weight, and the available interchangeable lenses tend to be smaller and lighter as well. To illustrate, one could carry an Olympus EM-1 MK II with a 12-40mm F2.8 Pro lens (equivalent to 24-80mm in 35mm terms), a 17mm F1.8 lens (34mm in 35mm), a 45mm F1.8 lens (90mm in 35mm), and a 60mm F2.8 Macro lens (120mm in 35mm). Despite these multiple lenses, the overall weight would still be lighter than a Full Frame Sony A7R IV with a Sony 24-70mm F2.8 GM lens.
Considering all these factors, micro four thirds is suitable for individuals seeking to enhance their photography with an interchangeable lens system, particularly those who do not mind purchasing second-hand equipment and are not limited to Olympus and Panasonic as their only camera body and lens options. Moreover, due to its lightweight and compact nature as a complete system, micro four thirds is an excellent choice for frequent travellers who desire a comprehensive range of lenses.
Olympus OMD E-M10 MK II – This particular camera served as my introduction to the Micro Four Thirds system. Its retro aesthetic, particularly in the silver/black color combination, resonated with me. The satisfying tactile feedback from the dials enhanced my shooting experience. Moreover, its compact and lightweight design sets it apart from other interchangeable lens systems. Equipped with a 16-megapixel sensor and entry-level sensor-based stabilization, along with basic face tracking capabilities, it proves more than adequate for my street photography pursuits. Interestingly, I frequently receive inquiries regarding the camera model or compliments on its appealing appearance when utilizing it for casual street photography. In my view, this camera serves as both a fashion statement and a reliable tool for capturing decent photographs.
Olympus OMD E-M1 MK II – The retro-styled professional-grade camera I possess boasts full weather sealing, ensuring its durability and performance even in challenging conditions. It features an ergonomic grip, providing excellent handling, and offers an extensive range of customizable functions to suit individual preferences. With its swift autofocus capabilities, remarkable sensor-based stabilization, and reliable face and eye tracking, it delivers impressive results. Moreover, it supports high-speed continuous shooting of up to 20 frames per second, while maintaining a satisfactory battery life. The camera also excels in video recording, offering 4K resolution, and benefits from dual memory card slots for enhanced storage capacity. With a 20-megapixel sensor, it captures detailed and high-quality images.
As I have acquired all my Micro Four Thirds cameras and lenses through the second-hand market, this particular camera has become my go-to choice when venturing into challenging environments such as heavy rain, dusty areas, or bushlands. The fact that I obtained it at a reasonable cost allows me to use it without hesitation, knowing that if it incurs any scratches or damage, I can easily replace it without significant financial burden.
Panasonic G85 – There were two primary motivations behind my acquisition of this camera. Firstly, I was intrigued by the widespread acclaim surrounding its 4K recording capabilities. Numerous reviewers had praised its performance, prompting my curiosity. Secondly, I seized the opportunity to obtain it alongside the Olympus 12-40mm pro zoom lens, which the seller offered at an exceptionally competitive price.
In terms of 4K recording, the camera yielded satisfactory results; however, I must admit that its video autofocus did not match the standards I had grown accustomed to with Sony and Canon at that time. This aspect proved to be a disappointment. On the other hand, the autofocus performance for still photography proved reasonably swift.
A pleasant surprise was the camera's user-friendliness when capturing still images. It features an array of buttons conveniently positioned for accessing frequently used functions. Furthermore, many of these buttons are customizable, allowing for effortless adjustment of settings without the need to navigate through extensive menus. This flexibility enables on-the-fly adjustments, significantly enhancing the overall shooting experience.
Panasonic GF3 – Following the sale of my G85 camera, I found myself in need of a device capable of accommodating future firmware updates for my collection of Panasonic lenses within the Micro Four Thirds system. After careful consideration, I opted for the most cost-effective solution available in the second-hand market, acquiring a camera in excellent condition.
While it possesses a modest 12-megapixel resolution and lacks certain common features, it must be acknowledged that, by today's standards, its focusing speed may be considered somewhat sluggish. However, due to its compact form factor, when paired with the diminutive Olympus EZ 14-42mm power zoom lens, it becomes a conveniently pocketable Micro Four Thirds interchangeable lens camera. Consequently, it proves particularly well-suited for food photography, where fast focusing may not be paramount, but a respectable wide-angle lens is desirable.
