Since DxOMark rated the GX7 with the Olympus 75mm having less resolution than the E-P1 (it is not a typo) with the same lens, I don't trust in their judgement anymore.

I'm surprised how much sharper in details is samsung nx1 as gh4. Is this really a 1:1 comparison ( lens, focus, resolution)??

First results for NX1 on DXOmark: http://www.dxomark.com/Cameras/Samsung/NX1

Detailed measurements are not posted yet.

Here's another "serious" review:

Videographers will find a lot to like in the NX1. For starters, internal 4K video quality is outstanding and slightly surpasses the Panasonic GH4, making the NX1 our new reference camera for internal 4K video recording. Add to that a well designed user interface, an effective touch screen with tap to focus, and useful video settings such a wide dynamic range gamma profile and the whole thing becomes a rather compelling package.

Gold Award.

I love this NX1 and truth be told its redundancy with my current gear is what precludes me from placing an order on one myself.

Well darn, I'm certainly not buying anything until NAB is completed! (Am waiting on seeing if the AF200 is real....)

Compares unstabilized (except lens OIS) and stabilized by Power Director 13 (the editor that works with H265 natively) software stabilizer. The first sequence is unstabilized and then the same clips follow that have the stabilizer applied. First day of crocuses, up close. Crocuses are small and close to the ground, difficult to shoot with a tripod.

Not just a price drop to US$1.3k, there was even an eBay seller which sold a bunch of brand new NX1 bodies for just US$1100! (but all sold out, still is nice to see how the prices are trending down)

Adorama has same price, but includes free Rode Pro mike + 64Gb SDHC card

The NX1 is arguably the 'best connected' enthusiast's camera currently available. Not only does it have a sophisticated Wi-Fi system, it also comes with Bluetooth 3.0 and NFC connectivity. Wireless networking connectivity uses both IEEE 802.11b/g/n and the faster 802.11ac networks with bandwidths of 2.4GHz and 5GHz, which are enough to stream 4K video wirelessly to a Samsung UHD TV.

Shots taken at high ISO settings were consistently clean and virtually noise-free up to ISO 6400. Softening became apparent in shots taken at ISO 12800 and increased with rising sensitivity. Interestingly, colour noise was relatively low throughout the sensitivity range and luminance noise remained inoffensive. By ISO 51200, both available light and flash shots appeared both soft and granulated, although they would be usable at small output sizes.

@ B3Guy. I've been playing around with the "calm" picture setting and bringing the colors back into balance and increasing the intensity by tweaking the color, hue, and saturation setting of that picture profile. I'm not going for a flat image. The image is totally baked in, which is something I can live with but others may feel differently. I thought GammaDR would be the end all be all, but like you said the color get messed with. I like an image where the whites are not grey or muddy/off-white and I think that's what draws me to the calm picture profile after I tweak it to taste.
