I've never owned a camera that didn't require a compromise.
the Nikon d3 I gave up detail and more exacting color for high iso and excellent focusing.
The Canon 1dx I gave up extreme detail for robust ethernet tethering and canon color which I find more pleasing than most.
With the Leica S2 I lose high iso and lightning fast focus for a more traditional camera, that shoots a very nice file.
In Motion it's the same.
With RED I give up small portability for a professional cinema look.
With the gh3s I lose log files for a small package and the Canon 70d I lose 4k, for excellent lifestyle mobility and thoughtful and accurate autofocus.
Would I like all the best attributes of the cameras I just mentioned in one package? Sure and of course I'd love it to be $4,000, but life just doesn't work that way.
The point most are missing is Canon has a huge user base, especially in the professional ranks.
They are also the only company (other than Sony) that makes professional still cameras, decent post production software with a lot of cross platform use with a professional cinema line.
Unlike Sony Canon is very deeply embedded in the professional ranks, with rentals or purchase on almost every metro area.
So if you work in advertising and mixed media, a case of Canons will pretty much cover everything I could/would/plan to shoot.
Is it free or cheap?
No, but professional equipment rarely is.
As I mentioned before, nearly all higher end digital cameras are very good, in both still and motion and the shoot budget, or talent of the artist will limit the production much more than a camera.
Internet conversation tends to lean to the negative. Don't know why, maybe it's just the human condition and you see it in this thread and that negative Leica thread, but personally I see things in a much more positive light.
I also know in the professional world, image creators don't grind on about cameras. Most have their preferences, most use what works until it either stops or something forces them to move upstream and if they can't afford to buy, they rent.
But nobody shoots poorly because of the camera and no great image is produced because of the camera.
I have and do own Nikon, Canon, Leica, RED, Panasonic, Olympus, Sonys and I've very, very rarely started production without a case of Canons and consequently rarely produced a project of any size that didn't have some or all content produced with a Canon.
I don't think anybody here needs to worry about Canon, Nikon or Leica's P+E. They're all fine.
IMO
