NEX FS700 April 2
This isn't really April 1 joke since this rumor has been out for several days.
Even though it's not still camera, it's 4K camcorder with Nex's E-mount. We will find it out in a few more hours. What that means is that Sony is fully invested in E-mount, but there is a conflict of interest too. The camcorders require higher quality lenses (size is irrelevant), but the still cameras users want pancake lenses.
