What Buyers Say
OM System OM-1 OM-1 Mark II
This user switched from the Lumix G9M2 to the OM System OM-1 Mark II for "run and gun" shooting and found it excellent, especially for mountain bike races. They praise its fast sensor readout, highlights exposure mode that improves shadow detail in raw files, and 10-bit video. However, the reviewer notes the lack of a true auto mode and the inability to edit previous forum posts, while also pointing out that custom modes can save configuration changes. The Q&A section contains numerous unanswered questions and a complaint about inaccurate product specs regarding integrated flash and included memory card.

- 10-bit video recording
- custom modes save configuration changes
- 2x crop assignable to lens button
