Looking to upgrade to the sony a7s of the 5D mkIII.
Whats peoples opinions on the A7s, is it just a band wagon camera or is it really that special.
Will be shooting for Video only.
With all that I've seen and read, The Canon 5Ds have and somewhat still are the bandwagon cameras.
They've been the Go-to because they were the first real DSLRs to be used for serious filming purposes back in 2007. The A7s, however, is one of the first DSLR's specifically designed for use in Indie film productions because it allows for incredible low-light performance, and its picture quality is one of the best in the DSLR market.
But you absolutely should do research into it and actually look at everything that people are saying about it.
My consensus, however, has found that the 5DmkII and mkIII, while being a favorite of photographers, has been the absolute last choice for many people looking into new cameras, in terms of both picture quality, noise size, ISO range, and overall versatility. People have either moved to the Micro-4/3rds range with the Panasonic GH4 or the Black-Magic Pocket Camera, or they've gone to the A7s. Or they've bought 2 or all three of these cameras, because of each camera's useful benefits.
Besides which, 4K picture is an extremely helpful and useful aspect that I would consider it unwise not to invest in at this point. 2015 really should be the point where we put straight HD behind us when it comes to shooting raw footage if we want to get the most out of our filming experience. 1080p I think is okay for phones and more special circumstance shooting, but your principal photography will look so much better if it can be shot in 4K.
The GH4 shoots 4K internally, the A7s shoots 4K with an external recorder, the Go-Pro HERO III shoots a form of 4K internally, and many other cameras will soon follow. Hopefully the BMPC will get 4K soon enough, and then people won't have to get the awkward BMCC, with its bulky and lofty footprint.
