The Only current Sony A7s Review vs GH4 Review shot entirely in 4K!

The Opening Music is “They Hit Without Warning” by Epic Score - They make seriously awesome music - Music was licensed through SongFreedom.com, and you can find them on iTunes here: https://itunes.apple.com/us/artist/epic-score/id440316841

Article on Equivalence: http://www.dpreview.com/articles/2666934640/what-is-equivalence-and-why-should-i-care

Please read it carefully, probably twice before making a comment or question about equivalence. There is some mis-information out there on the topic, I get a lot of comments about it, but there is a lot of misunderstanding- that article sets the record straight.

Thank you guys for all your shares of this video as well as the comments and feedback. I can’t tell you how often I get great input which helps me learn about what I can do better. I am sincerely trying to do my best to provide to you the most accurate information you can get about both of the top end mirrorless cameras in the Panasonic GH4 and Sony A7.

This Epic Shootout took a significant amount of work and resources, and there is also a lot of information I left out for the sake of time. I actually performed a series of Dynamic Range tests that will support much of what I listed, and I will add a link to my blog when it is all confirmed and organized. That test is more scientific and easily repeatable by anyone who owns these cameras.

The Opening Sequence was shot almost entirely with the Panasonic GH4, please support our sponsor BHPhoto.com who lent us some very expensive gear to get the 4K tests out of both cameras:

- Nicolas Pappagallo From PAC: http://www.photoadvclub.com
- My Good Friend Brandon for his help with the Bow and Arrow Shooting and other support with certain reptiles (none were harmed in the shooting btw)

Production Notes:

- Sony A7s 4K video was recorded to the Aja Ki Pro Quad Recorder, we used the same recorder for the 10-Bit GH4 4K video and were unsuccessful recording 10-Bit through the HDMI port.

- GH4 was a joy to use. The internal 4K recording and $800 less-in-price are really what made it stand out. Whatever magic is happening inside that little camera is special. The A7s takes more time to learn to navigate.

What are all those weapons about you carry there?
SANDE049 (2 months ago)
Outstanding review! You are truly rewriting the way to do a comparative
test. No pixels-peepers obssesions, clear conclusions, serious
presentation, comercial distance about tested gear, objectiv results and
all it just really matters - with an overall excelent image. Thanks for
your work. You've got a new reader, from now!

Great review and well balanced but whats with the guns? Spoils the whole
review getting 10/10 can only can give 9/10.
Lose the guns IMHO and concentrate on the photography.
Just found you channel, subbed ya.

the begining totally gay. Also buffer is not when camera writes to memory
card. it;s when it writes to internal memory - ram, NOT memory card.
Peter Kelly (2 months ago)
I have to congratulate you on a well balanced and sensible comparative
review; a difficult thing to do at the best of times. You managed to avoid
the endless, time-wasting drivel that most seem to fill their videos with
too!

However, I have one very minor observation. The issue with moire is going
to depend entirely upon spatial frequency, which is why you get differences
between the cameras and the output resolutions.
When the frequencies are 'resonant', you will get interference patterns,
otherwise known as moire. Change the frequency of one, either shirt,
sensor, or output, and it can disappear entirely. Unfortunately, it is one
thing that is almost impossible to avoid in every situation and the reason
why newscasters are asked not to wear clothes with fine patterns.

Test results 100% A7s. Thanks +MichaelTheMentor I wanted to buy GH4, but
today i looked A7s, i was watching a lot of movies and compares, and
couldn't decide. You made it clear for me. I'll buy A7s. Thank you! You've
got a sub.

Great video, great intro, and I love guns. This guy puts all this time
into the videos and you bitch about his intro and act all weird because he
had guns? Ah, the internet.
Takeonparis (4 months ago)
This is the greatest camera review I've ever seen. I say that as a very
angry, bitter man who doesn't give away compliments for free. Especially
not for photography or writing. You answered every question I had about
both cameras without coming off as a jackass or looking, sounding, and
being like "Roger" from American Dad. I think I've probably seen about
4000+ video reviews since I first started shooting. This was the best by
far.

A7S: 8
GH-4: 4

I found I like Fujifilm, Olympus, Canon, Nikon and SONY color more than
Panasonic and Samsung. Maybe this explains why Pana and Samsung have poor
JPEG.

Awesome review of both camera. I'm very tempted by the Panasonic GH4 for
traveling.

for that intro.... Fuckin awesome

Hello everyone, I just have one question regarding the MFT 'crop' factor.
When You're talking about Depth of Field and that a MFT f/2.8 is going to
have a DoF equivalent to f/5.6 on a FF, are you JUST taking about the Depth
of Field, or does that mean that the MFT lens F Stop 2.8 is actually
brought down to 5.6 in terms of how much light enters the lens? Than You!
Alexander Levit (21 days ago)
Loving your unbiased, straight facts shootouts! Excellent in depth, rugged
tests - thank you. Can you consider doing a photo shootout (Dynamic Range,
Auto Focus) between the Sony A7ii vs whichever FF cameras you feel are top
contenders. Thank You. I understand that the a7ii's AutoFocus isn't quite
there yet. Silly question, through a firmware upgrade can Sony improve the
AutoFocus? Can a FirmWare update increase the Burst mode (continuous
Shooting FPS)? Thank you and Keep up the EXCELLENT work you do! 
Carlos Oraison (13 days ago)
I enjoyed your in depth review. I didn't understand the beginning of the
review with the gun. I appreciate the time and effort you have put into
this review. I have subscribed and look forward to watching more videos.
Thank you.
Tim Pek (6 months ago)
Very helpful review, best of the best.
Richard Altenburg (22 days ago)
76 people have no idea how much time and effort it takes to produce a
review video of this high quality. I respect your work and will continue to
enjoy your videos.
Mark shirley (10 days ago)
Thanks one of the best camera reviews going - I'm with the other post tho
on the gun thing - it might be my European sensitivity coming through :-)

30:00 lol show zeiss 24-70 F2.8 ZA SSM for A-mount, but said nothing about
the adapter Sony LA-EA4 or LA-EA3 =)
Sony have nice FF Lenses: Zeiss 135mm F1.8, Zeiss 85mm F1.4, Sony 135mm
STF, Zeiss 16-35mm F2.8 ZA SSM and many Minolta lenses. They all work with
AF nicely
