Olympus E-M10 Mark IV Review: Compact and Powerful Camera

The Olympus E-M10 Mark IV, a compact and lightweight Micro Four Thirds system camera, showcases impressive features such as a 20MP sensor, 5-axis image stabilization, and 4K video capabilities. With its sleek design and advanced technology, this camera promises to deliver high-quality images and a seamless shooting experience.

After replacing my older Sony system with the OLYMPUS E-M10 Mark IV, I have been thoroughly impressed with its performance. The camera is incredibly easy to use, and its lightweight design makes it convenient to carry around. The 20MP sensor produces sharp and vibrant images, while the 5-axis image stabilization ensures that my shots are steady and blur-free. I particularly appreciate the flip-down monitor and dedicated selfie mode, which make capturing self-portraits a breeze. Additionally, the 16 art filters add a creative touch to my photos, and I love the nostalgic feel of the new Instant Film filter.

During my initial use, there were a few minor drawbacks that caught my attention. Firstly, the charging process stops when the camera is turned on, which limits the option of using an external battery for long exposure shots. Secondly, the EVF (electronic viewfinder) is activated by eye contact, which can be a bit inconvenient when switching between reviewing images on the LCD screen and using the EVF. Additionally, the battery door lacks an automatic lock, requiring manual adjustment. However, these issues did not significantly impact my overall experience with the camera.
