If your filming an important short film keep the camera department single unit. Lighting will be sacrificed if you set up a B cam, and you will need more crew. It can actually be more work not less.
The reason you hear that canon lenses are not sharp is because their sharpness is not very consistent edge to edge and throughout all the apertures. The chances of a photographer shooting at 2.0 with the subject at the far right of the frame is unlikely, but very likely for cinematography. Cine lenses are sharp edge to edge and much sharper wide open. Even the cine version of the canons, at least by my testing, are sharper wide open. Especially when you look at images in 4k, the high pricing of cine lenses start to validate themselves.
This is horrible advice. Maybe you should write a novel, filmmaking is a visual medium, the visuals matter.
Where is are the mindless advocates for 4k? From the look of this thread its 10:1 haters:fanboys. Just saying.
Be respectfully aggressive, and give clear and concise directions. If you gave a direction and you know if your heart that it wasn't easy to understand, address it then and there. Do not let anyone walk away without them knowing exactly what they are supposed to do. Or if you don't know exactly what you want say give me 5 minutes to make a decision or tell the crew member to make the choice themselves. Nonetheless, once a direction is given it needs to be clear for everyone involved
As long as your crew is paid and fed, feel free to ask a lot of them. Get good results and ask for even more. You're the coach and players need to be motivated and pushed if your going to create something victorious. As long as the end product looks fantastic crew members appreciate your high expectations and will bend over backwards for you on the next one. Everybody just wants to be part of good work.
You should not lend a hand to G&E unless you are heavily under resourced and are working with a skeleton crew. If you do have resourced departments, its bad form. A director should never have to touch equipment, if they do they department is slacking.
