You can't draw conclusions about sharpness from this comparison. Both cameras are tack sharp, at least the ones I have and the GH4 is every bit as sharp as the Sony A7s. Keep in mind the A7s doesn't come out of the coma until it hits ISO 3200. 3200 and up is where it starts to shine, I love the noise pattern at higher ISO's, those huge photo sites produce a very film like look. Even models have commented on the noise pattern and called it film like.
The real and very visible difference in challenging shooting situations is dynamic range and color depth, something the GH4 isn't great at and even at lower ISO's the A7s looks better and produces more manipulable raw files.

mike kobal: Since I am using the A7s and GH4 professionally, I find it very difficult to compare these two cams. Obviously, the FF sensor is vastly superior for stills, in video mode, the A7s kills the GH4 in HD mode (and most of the competition) the GH4 has the edge when one needs lots of depth of field in good light and internal 4k recording. keeping both.

I haven't looked at the samples, I find it too difficult to draw conclusions from general images. However, I have been shooting with both since they became available. I find the low light performance and dynamic range of the A7s sensor spectacular. I don't pixel peep much these days :) The GH4 produces respectable results up to ISO 1600 and I would not hesitate to use it professionally on journalistic assignments. I think this is where the GH4 shines, it would be my 1st choice for another trip to Africa. The A7s, A7, A7r for controlled shooting environments on location and in the studio.

mike kobal: Sorry, but a sensor size of 44x33mm cannot be called medium format by traditional definition.
This is a APMFS-C sized sensor (Advanced Photo Medium Format System type-C)

@ogl
WRONG is right when you only read half of the first sentence. Learn to read.

Horshack: S-Log2 support indicates this is targeted at high-end video production. I'm guessing the price will land at $3,299.

that was also my guess, around 3K

Jay: over hdmi? does that mean it won't record 4k to an SD card?

it won't -I watched the live stream, only external /:
hopefully this means a reasonable price

the addition of the 50mm equiv officially elevates the X100s into professional hss territory. Bravo Fuji.

zodiacfml: minimal PP and stage? then try this:
http://www.telegraph.co.uk/culture/culturepicturegalleries/9698490/Photo-series-of-the-bond-between-a-grandmother-and-her-odd-eyed-white-cat.html?frame=2407644

another great series, thanks for the link, minimal pp, yes,
not so sure about minimal stage. Not that it matters, both photographers, Elena and Miyoko share very personal moments focusing on the joy of life and love, clearly hitting the nerve of many, surprisingly, even here on DPReview, there are more positive comments the negative, a sign that not everything is lost ;)

Samuel Dilworth: This rampant kitsch (which runs amok on sites like 500px) is destroying our ability to see. It’s like the ‘loudness war’ in music: everything is turned up to eleven to attract attention. More is without exception more in this world.

So it follows that if a dog is good, and a pot-bellied toddler is good, putting the two of them together at sunset on a misty farm is even better. (Duh!) If you formulaically combine:

• fluffy pets
• children
• sunsets
• snow
• backlit mist
• flowers
• bucolic artefacts
• fabrics blowing in the wind
• blurred backgrounds
• very warm, highly saturated colours

… you arrive, as Shumilova did, at the apogee of this aesthetic – the equation can’t be denied! – even though you’ve truthfully created an absurd parody of beauty.

As this garish view of the world becomes normalised, it becomes harder for people to see other, better possibilities.

how exactly does this destroy our ability to see? another non nonsensical comment by a frustrated pixel peeper who has lost his way searching for values at 400% magnification, mtf charts and lens hood calculations.
