Just a little correction about the phrase "Currently there are no other 4K interchangeable lens cameras out there for $799." - the Samsung NX500 is $699 now (was $599 last week). I know that there are a lot of caveats in the NX500, but I'm mentioning just for the sake of correction.

About the high framerates of the smaller cameras: yeah, it is upscaled. Full specs of the 3 cameras are already up in Sony's website. From the RX10 II page, in the HFR section: http://www.sony.net/Products/di/en-us/products/ht7k/specifications.html?contentsTop=1 "<Sensor Readout Number of effective pixels>Quality Priority:240fps/250fps (1,824x1,026),　480fps/500fps (1,676x566),　960fps/1000fps (1,136x384)/Shoot Time Priority: 240fps/250fps (1,676x566), 480fps/500fps (1,136x384), 960fps/1000fps (800x270)"

If a good soul here good make a low light movie comparison between the LX100 and the NX500 with the same iso and aperture, I'll be immensely grateful.

​Heat issues, probably (or just a good excuse for segmentation)

http://www.photographyblog.com/reviews/samsung_nx500_review/ There are some video samples there - but not very conclusive, with kit lens and autofocus enabled. The 4k looks a little bit soft - but again, could be just misfocusing. The 1080p footage looks VERY sharp.

I've used legacy lenses with my GH2 (and with a Olympus E-P1 in the past for stills) without peaking, with very good results. But a shoot a lot in live concerts, with poor lightning, and in this conditions peaking helps a lot compared to using a loupe in the LCD (I have one too).

​I've done it once with my 45-175mm and my E-M10 (just 3 axis IBIS). At least for still, looking in the EVF while framing, the IBIS in the E-M10 looked a little bit more stable compared when I turn off the IBIS and use the lens OIS.

​Never used the NX1, but I use peaking in my Panasonics. For fixed shots (where I don't change de focal distance I think that the enlarged view is ok - even preferred), but when I have to change focus while filming, pressing a button to bring the enlarged view (if you are working with non-native lenses) could introduce some shaking in the camera; I got better results with peaking.

No peaking in 4k/UHD is a deal breaker for me. But Andrew, if you could make some comparison shots between the NX500 / LX100 (I'll buy one of those in 2 weeks), especially in low light, my thanks in advance.

​A lot of cheaper cameras have focus peaking. The 4k crop could be understandable because of processing / heat issues / market segmentation, but no peaking in 4k s a very BIG flaw.

Well, no focus peaking in 4k was the final deal breaker for me - more than the crop factor. A shame, since the first samples that people are putting in youtube have very good resolution.

I'm interested in this new sensor. Since the E-M1 mark II rumours mention a 18mp sensor too, I guess that finally a new MFT sensor is coming.

If the 4k image is generated from a 1:1 3840 (or 4096) x2160 pixels crop from the center of the sensor, and the pixel size from the NX500 is a little bit smaller than GH4's, I guess that the crop is a little bit higher than the GH4's - then the 2,58x crop looks correct.

In other forums people noticed that the Samsung now says that the NX500 have a "DRIM Vs" chipset (the NX1 have a DRIM V). Probably a underclocked version.

At least the 4k crop mode was confirmed in the Korean NX500 site: http://www.samsung.com/sec/consumer/store-only/store-camera/product/EV-NX500ZAMIKR (you can use Google Translate to help) The same site have a formware for download, version 1.0 - that means a defintive first production firmware.

​The low light performance was better than I expected. The softness is present, but worked well with the video. Only the aliasing was perturbuing, when filming the car lights.

Kind a bummer for me too, because I want to buy the NX500 for concert handheld recording - which means that I need OIS. With my GX7 I use the 20mm f/1.7 a lot (with the 2x crop factor it is 40mm in FF), then the 38,5mm with a 16mm (widest OIS lens in Samsung lineup) is similar. But I was wishing the 24mm field of view. But a 1:1 sensor crop probably will eliminate moire, or I'm wrong?

​I doubt it. All these rumors sites only publish compliments for the brands, never criticism.

​Some people said (I guess John was one of those) that you can change the exposure settings...but only using the touchsceen, not the physical controls.

​Vlad, do you have any footage sample made with the Ninja Star, especially about moire, aliasing and softness? Only 30fps was available, not 24p, with the Ninja and the Star? And when using the Star, the LCD display in the camera stays with live feed or an external monitor connected in the Star is mandatory?

Rio de Janeiro, I live here (the last shot was made near my apartment). Brave guy to bring a Phase One to Rocinha (the first shot) and return with the camera back home.

​Thanks, that was exactly the kind of footage that I was looking for.

Good video too. In good light the image is really good, but the dark segments in the begenning are somewhat noisier, no?

​When using adapted lenses, you must dial manually in the focal lenght of the lens that you're using; you can use a adapted zoom lens, but will have to choose a focal lenght, dial in the value and stay with it. With m4/3 zooms, there are no problems, since the focal lenght value is transmitted electronically.

Downloaded the John files (Curiosity is a great video, by the way). One improvement is visible: tree leaves don't became a blotchy mess, like the E-M5 - the bitrate helped a lot. Some doubts about sharpness (because of some other test videos) and low light performance.
