otto k: I'm sure additional layer of glass on top of the sensor in no way affects the image quality...

@otto k
that occurs with rangefinder wideangles, that is, with small exit pupil distance. With telescopes such problem doesn't exist

So this does work only with LV, right? What if user accidentally switches to OVF?
I recall in some cameras shutter motor is coupled with mirror.

PeaceKeeper: Nikon used to have removable AA filters WAY back in the day. This is not as huge as concern for the camera and sensor as you are all making it out to be.

which models?

cosinaphile: why didn't they make the flange shorter with a sturdy adapter with electronics .... there are 100,s of thousands of users all over the world who have lens collections that could be used in a legacy fashion but the depth here is like an slr
it reminds me of the pentax mirrorless debacle with the long flange and no vf a few years ago the k-01.... mark newmans regret..... it could have been something with a short flange distance and a corner evf ....

@leonche64
Adapter? Just make it xD and none of Sigma SA lenses are made for CDAF, but most m43 lenses are. And there
What's with EF-M mount? it seems to be wider than Sony E which can accept FF.

@leonche64
Sigma is a participant of m43. They already produce 4 lenses for mirrorless which cover aps-c. Also Oly 25/1.8 and 75/1.8 are designed by them.
Also, EOS M sells an order of magnitude better than any of Sigma cameras. It's not seriously considered by dpreview snobs because it's not 'pro' enough, but it sells well.

ottonis: From ISO 1600 and beyond the PhaseOne is clearly inferior w/r to noise when compared to contemporary FF cameras such K1 etc., even when scaled down to equal resolution/size.
I really wonder why these MF sensors are lagging behind FF sensors in low light performance, considering their significantly larger size. Is that possibly caused by tuning them for highest DR at base ISO? Or are the most recent advancements in sensor technology just too vulnerable in order to provide sufficient (silicon wafer) yield rates?

people shoot medium format all the time... it's called Fuji Instax xD

Samples show very modest improvement over Pentax K-1 in pixel-shift mode.

@WastingTime
the former is true the latter is BS. In pre-merill DPs lenses used to nearly lie on the sensor. Sigma's own 19/2.8 and 30/2.8 DN interchangeable lenses are almost same as those used on DPs with foveon sensors.

Agree, they should have used m43 mount

whyamihere: I'm surprised camera data encryption isn't already a thing. We're talking a few KB of data added to each image & minimal processing power on the behalf of the camera to ensure that information remains secure and/or confidential. The media most cameras use - Secure Digital - supports encryption; a SD card's ROM could probably be modified to secure erase after too many password attempts.

With that said, encryption is only as good as its design and implementation. Companies get hacked all the time, and their cipher data could be stolen and distributed. Backdoors are made because some companies willingly hand the keys over to any government who politely asks. Heck, even the few bits of information passed back & forth between camera & the card could leak enough data for a crack. Nothing is foolproof, and encryption might just wind up being a mild inconvenience instead of a huge detriment.

Before anyone cracks wise: This is part of my job. I think about security in practical terms a lot.

...because camera makers and camera users are very conservative. That is why we have black fake DSLR style.

naturetech: We need to also be naming, shaming and sanctioning the governments that limit the freedom of the press in their nations.

And when a press organization abuses its power and engages in deception and slander, it needs to be held 100% accountable.

Its not just goverments. Even in "liberal" California you might get attacked for wearing Google Glass.

But what about Pentax/Ricoh?

ChroMagnon: I am going to play devilś advocate here, even though I would never have this thing. The Relonch website indicates who the audience is (hint: itś not us, DPR readers). The key traits are: think the SLR is complicated, don´t like to edit photos, have a ton of photos they never review, don´t like the look of a trad camera, don´t think cell phone photos look good. (The CEO calls a DSLR a ¨20-button plastic monster¨! LOL!) So the audience is people who want high IQ but don´t want to do what it takes to get nice images. They probably have market research (shared with their venture capitalists) to this effect. I definitely know a lot of people like that and Iḿ sure you do, too. Relonchś answer (promise) for this audience is to sell the photos, not the camera: to edit, retouch and deliver photos that look great without the user having to do anything. For that audience (not us), that service may be useful. BTW, the fee is $99 to reserve and $1/photo to use, not $99/mo.

@Gazeomon
it appears to be Galaxy NX with 30/2 prime, so I don't see problem from IQ viewpoint.

Hm, how they will protect from stealing the camera?

They managed to make Galaxy NX even more ugly. An accomplishment.

Jylppy: For people with more money than time this might be an interesting proposition. However, sending all photos to "some service" where AI and humans edit the photos is something that may concern people. ("How did that end up in Twitter?")

In film times, minilab workers might copy photos just as well.

marc petzold: Funny thing, someone (the company think they're clever!) have bought all the remaining ressources from the Samsung NX Galaxy Wireless DSLM Stock, and put them with a cheap prime into that kind of "style" leatherette case. Privacy is also gone, since the images are being transfered to the companies server, and being processed to their "liking"....well, something for the hipster or FB generation - which want 101% share their once was before being called "private life" moments then...really rediculous, for 99$, i'd get a cheap analogue Canikon SLR with a nice nifty-fifty prime lens (albeit not digital) and have more fun getting my film rolls being developed...and keep my privacy, too.

This is the Samsung 20 MP APS-C Galaxy NX Wireless, which is running on (an old) Android OS, it matches also perfectly the Siluette from the now being called "Relounch 291" Camera...and being used for this Project.

https://www.amazon.com/Samsung-EK-GN120ZKAXAR-Wireless-Mirrorless-4-8-Inch/dp/B00FB2X0B8

Is it really possible to find SLR with 50 mm prime under $100?
To keep privacy with film you must develop it yourself...
How this adds to cost?

This is even more ridiculuous than Hasselblad Lunar and K.
