OM SYSTEM OM-3 Overview

Technology for Evolving Creatives
The OM SYSTEM OM-3 arrives to deliver flagship-level performance, customizable creative tools, and robust video capabilities, making it a great all-around camera for diverse scenarios such as cityscapes, street scenes, and urban nature settings. Adopting the 20MP Stacked BSI Live MOS MFT Sensor, TruePic X engine, and the 1053 AF points native to the OM-1 Mark II, this compact system proves to be a giant in capabilities.
Timeless Elegance and Innovative Design
The OM-3 prides itself on conserving the timeless elegance of the SLR camera. Its design repurposes the traditional dials to provide valuable access to customizable tools, such as a creative dial that allows easy transition between color and monochrome profiles, an intuitive button that unifies computational features such as Live ND and GND, focus stacking, and more.

With easy access to the computational photography button, the user is allowed to harness a wide array of creative tools, such as capturing light trails free from urban light pollution or combining various focus points to capture the wonders and details hidden in the world of macro photography.

5-Axis Image Stabilization
The OM SYSTEM 5-axis image stabilization provides up to 6.5 shutter speed stops of compensation for the center and 5.5 stops for the corner. When paired with compatible lenses, the camera supports Sync IS delivering even more powerful image stabilization at up to 7.5 shutter speed stops at the center and 6.5 stops at the corner, ensuring blur-free images in a variety of scenarios.
Video Features
Optimized for video creators, the OM-3 allows for 4K video recording at up to 60p, seamless mode switching, heat management for extended recording, and new OM-Cinema video profiles. The dedicated video dial makes switching between still, video, and S&Q mode a breeze, easily recording slow or quick motion videos at frame rates ranging from 1 to 120 fps.
OM Cinema Mode
The OM-Cinema Mode welcomes new video color profiles meant to help the user achieve cinematic quality with advanced settings tailored for professional storytelling.

Are high resolution images also 14 bit?
Asked by: mark
High resolution images are not inherently 14-bit. The bit depth of an image is independent of its resolution. High resolution images can be 8-bit, 12-bit, 14-bit, 16-bit or even higher, depending on the camera's capabilities and settings.

Will my old OM-1 lenses fit and be used with this camera?
Asked by: David
Thank you to Lucia, Charles, and Matt! Yes, just for clarity, the lenses to which I was referencing are the "old" OM. type from the 1970s and early 1980s (later-acquired lenses). It's good to know that there are adapters, and I will definitely look for them, now with your help. Thank you again!!!
