I agree about Curtis - one of the best, informative, no-nonsense reviewers on YouTube.
Thanks Ed - you were right about Tim's work too!
I owned a Canon 5D Mk III and loved it (great video, even greater stills. Seemed impossible to take a bad picture with that camera).
When the Sony A7S came out I bought it and sold the 5D. I actually made money!
For video - waaay better. Its renowned light performance gives you a lot of freedom to film. Ergonomically it is much easier to lug around.
The A7S is no as good as the 5D for stills, but it's not that far off. Its in-camera colours aren't as good as Canon, but you can fix to some degree in post. Its menu system is a bit intimidating, but thanks-be to YouTube and tutorials.
Finally, the corporate direction of Sony seems far more progressive and exciting than Canon. It just feels like they are more responsive to the modern camera audience.
That's my take and experience anyway.
Amazed no one has mentioned the price difference. The Small HD is a potent little unit but the Video Assist is also 1080p in a small form factor, is significantly more affordable and offers pro res recording.
The only real issue is that Blackmagic Design are yet to release it.
No offence, but journalism 101: Who, what, when, where, why, how?
Who can use this? Sony A7s?
What will the cost be?
When will it be available?
Where can it be purchased?
Why didn't you prepare these basic questions before speaking to this man?
How cna we find out more (nothing on their website)?
I used to own the Canon 5D MkIII and sold it for the Sony A7s.
I loved Canon's pictures but the lure of improved video on a smaller full frame camera was irresistible.
Not disappointed! A7s takes great video and also very happy with stills. Skin tones and colours are not quite up there with Canon, but still look beautiful thanks to full frame goodness.
And the smaller form factor really gives it a "use it anytime" feel. My old 5D made taking awesome pics a breeze, but was a lot more effort to haul around.
Just my opinion.
