Is the leica m ev1 good for video?
Honestly, the site doesn't tell you much about the Leica M EV1 for video. Its page covers the 60-megapixel full-frame sensor, the electronic viewfinder, and the lens list, but nothing on video modes or a flip-out screen. The one relevant spec is that the body has no stabilisation, so handheld footage will shake unless you use stabilised lenses or a gimbal.
Our video guide covers what matters most for filming: audio, a screen you can see, and a wide lens. Check the body's video specs and screen before you buy. If you do film with it, a wide lens such as the Leica Elmarit-M 21mm f/2.8 ASPH gives a useful view, and the audio section explains how to budget for sound.
