Mark I think a used FS7 is a think to take seriously. Maybe not Dougs shiney one with all the bits but there are ones around 4k
Mirrorless suck bigstyle with the poor ergonomics and lack of ND.
Certainly - another FS7 should be on the radar for Jason's purchase. And I don't disagree that mirrorless can "suck bigstyle".
I'm an "old-school" shooter myself, and have always preferred the ENG style shoulder mount, balanced camcorder to the palm-corder, DSLR, etc. But this old dog has learned a few new tricks. The original post from Jason talked about "8 hours running around" and not keen on the size & weight. And because of that same scenario, I have thrown my Sony 18-110, etc on my little a6300 for a day or two of fast-paced (and extremely down & dirty) shooting. And the client did not see a difference between the shots I got with it (using scene file I created on it) and shooting log on my FS7. They cut together very nicely - and I got many shots I wouldn't have with a bigger rig. It's not for every shoot certainly - but for very little $ - adds to the package. And the newer, better AF is certainly impressive.... and I personally would prefer great AF for my stills / gimbal cam then my FS7, FX9 (or A cam) in general.
