Summary: Video was decent quality but there was so little use support either in the box or online that it was rarely used. Bought this for a work project that I finally wound up using my phone for because I had no idea how to use this.
Summary: Amazon should not have put these three cameras, the M400, M40, and M41 on the same page. The selection buttons imply that the main difference is in the memory capacity and configuration. I purchased the M400, only to discover when I received it that it has no optical viewfinder.
