I know there are a lot of egos involved in the creative world but even by that standard there are some amazingly 'bitchy' comments coming out here. I loved the less financially empowered one :-D
I make a living in the creative world (have been for 20 years)...and anything that is an improvement on what you were using before is worth looking at. 5D, C300, BMCC it really doesn't matter because we're all trying to do it better for less (money or time). You wouldn't be even on this blog if that wasn't true.
The really smart ones in this industry keep an open mind, look at the developments and explore the options (while still making money doing paid work).
This firmware is less than a week old so even the skeptics among us would have to say it's early days with a long way to run. And yes it's a development in beta phase (not pro ready) but to those saying they wouldn't use it for pro work?...I don't think anyone is suggesting they should, though I am sure there will be the pioneers among us that will tempt fate...but of those, it is quite often 'Qui audet adipiscitur' (and no that doesn't mean 'if I don't agree with you I piss on you' but simply 'who dares wins').
