Been in the business for 30 years. Shoot all kinds of events and even shot a few Independent features. Have a film equipment hire business as well.
We had a local film saying "Trent" it basically covers anything to do with prep, organisation, research, having the location organised beforehand. Knowing who you spoke to and letting all know everything. Example being "If the Trent's not right, everything that follows won't be either." "The Trent has to be right." "You have to have a good Trent on your film" It was named after a production manager who was the best organised person you could meet. Everything was alays smooth when he was onboard, no surprises or let downs.
I bought 2 GH4's In May, and boy am I delighted with them. I shoot a lot of fashion events and other events (concerts, corps, weddings, web promos). I hung onto my
2 HVX cameras for more than 6 years and they gave me no trouble whatsoever. Only that after 6 years they were very dated. The reason, Panasonic's promise and no delivery of HVX like form factor 4K Camcorders with a MFT sensor (never happened , never will) I was reluctant to buy GH4's, as I already had Canons and I hate DSLR form factors. In the end I gave in and I have grown to love em. full frame owners will say I can shoot at 4000 iso with a clean picture and have no lights. But I will say well if you never use lights then perhaps you shouldn't be filming. GH4 shoots clean to 1600 iso. with majority of HD camcorders you were lucky to get 500 iso. Even the BMCC 4K only gets 400. When I shoot a wedding on weekends and then go into the studio on monday to dump my footage to the studio who hired me. I while waiting see the other guys filming. The 5D users never use light and everything looks so flat.
I may use a LED bank and a on camera one. But it looks gorgeous.
I seldom need to edit out a missed focus shot (I still bring along my HVX's as wide safety's and as extra angles. But the 5D users stuff has non stop focus pulling and missing.
See where a 5D user maybe on say 3200 iso at f5.6. I can be on 1600 at f 2.8 and have the same D.O.F as he. So my images should be as clean. 2.8 on a full framer in a catch it on the run situation (totally opposite of a scripted, blocked out, acted, controlled situation with a large monitor). Is often a hit or miss. Cannot wait to get the Atomos Shogun to shoot 4K uncompressed.
