"Yes, it’s F1.2, but it’s transmitted light T1.3, which is what you would use setting exposure. F1.2 is traditionally considered to be a full 1/2 stop wider than a F1.4. While T1.3 is only “.1” less, at this end of the scale, .1 actually matters" T1. 3 is '.1' less than T1. 4, not f1. 4. Your whole argument here is flawed, you're mixing measurements. Its also slightly dumb to pick on them advertising it's f number when literally every stills lens uses that measurement, only the Samyang cine lenses quote the t stop.
I'll throw in another recommendation for a sachtler head, we got the fsb8 for our fs5 and it's an enormous upgrade from the manfrotto we had previously. Not sure what the minimum weight is but I have the counter balance set to 2 for the fs5 and it's pretty light.
We're using a set of Miller cf legs, can't remember the model but they're the four section ones, sits way above my head fully extended or it can drop down to about a foot off the floor. Total price was £1500 but that's not as far away from $1500 as it was a month ago!
For anything under 2gb wetransfer is hard to beat. Anything over that we use myairbridge, up to 20gb for free. I've found it very slow to upload to so I'd avoid it for anything urgent if you can. We tend to send previews with either wetransfer or straight on to vimeo and then send full quality finished stuff with air bridge.
If it's a proper controllable set you could move the light to simulate the sun moving throughout the day, if it's a live location you'd need to composite. Depending on framing and the relative positions of the shadows and talent you could even do it without green screen, you'd just need to have the tripod absolutely locked down.
I'd definitely recommend the Fotga DP500ii, I don't have the hard stop version but the base unit is extremely solid for the price and I entirely regret not spending the small amount extra to get the hard stop version. I'll definitely get one as soon as I can justify it.
I would also highly recommend the Fotga, I bought one a while back and it's a very solid piece of kit. My business partner has a Redrock Micro, it's possibly been updated since (I've no idea when he got it) but the only difference is that it's bigger and heavier. The Fotga is actually better featured, on the cheaper model you can reposition the marking post (handy if you're pulling and operating) and there's a slightly dearer version which also has hard stops. Definitely get the quick release version, I bought the non quick version as it was cheaper and I didn't want to spend extra in case it was crap, I very quickly bought the quick release for it.
