It says on the B&H product page that "weather and dust sealing ensures this system can stand up to all environmental conditions professionals find themselves in". IDK about focus peaking though.I'm really into the concept overall. Couldn't care less about putting it on an Actus or adapting Canon lenses etc., but if the AF is sluggish and/or the EVF is average it'd kill it for me. It needs to be fast, fast, fast to be viable as a reportage camera. Does anyone know if it has focus peaking? Weather sealing?
