I don’t talk about this much, but I shoot stock video for Shutterstock, Getty, Videoblocks and Pond5. Lately I have been using the Samsung NX5 and I LOVE this camera! I have always shot with Canon gear and am seriously considering selling it all and switching to Samsung, the trouble is the lack of Samsung lens options. I have been using a Fotodiox Pro EF-NX adapter to run some of my Canon lenses on the NX1. I lose all the electronic communication with the lens so no autofocus, aperture or IS. I can live without those for video work and the results with my long Canon lens has been awesome.
