Other reports say ISO 12500, not 125000.
justmeMN: "US $649 (Canon EF mount)" Yikes! :-)
@dleemans: Of course, but what if you already have the camera you want and neither want to buy nor carry a second one, a camera that would come with maybe just the size and weight because of which you chose to buy into a mirrorless system in the first place?
Mssimo: I wonder if they could make speed booster for Medium format lenses onto full frame (sony a7) cameras.
@ProfHankD: Nice idea, but remember that the MFT Speed Booster was designed for a thicker filter stack and thereby image quality would be slightly reduced especially at large apertures when used on a Sony body...
fmian: I just never understood why people buy into formats that don't have the lenses they want to use, and instead opt to spend more money on compromising performance...
What is so difficult to understand? There are valid reasons for choosing a smaller-format camera, even if it is just the option of having a smaller and lighter setup for everyday applications. Or because of the increased telephoto range and macro resolution. So the decision has been made, the Micro Four Thirds camera has been bought along with a couple of lenses. Now why should I buy and carry another camera just to use the full-frame SLR lenses I still have and like and which significantly broaden the options I have in terms of shallow depth of field?
RPJG: "offering the attractive option of a 25-49mm equivalent F1.3 lens (F2.5 equivalent in full frame terms)."
When describing equivalence for f numbers, I wish you'd separate out the two separate factors, i.e. exposure equivalence and DoF equivalence.
'Exposure equivalence' is not a meaningful concept. When using equivalent ISO settings (instead of numerically identical ones), which of course is what we have to do when 'equivalence' is what we're after, then by using what you misleadingly call 'DoF equivalence' both DoF and shutter speed will be the same across sensor sizes.
If a society wants capitalism, it gets capitalism. Intellectual property and copyright are inherent to capitalism just as plain old physical property and the freedom which is significant in a capitalist society: the freedom to make use of property to extort and exploit.
Henrik Herranen: Dear Damien Demolder,is there a good reason why you don't revise this article and remove the following incorrect statement: "for the specification it is a good deal more compact than a similar lens for a full-frame or even APS-C system".
It is not. In the Full Frame world there are lenses like the EF24mm f/1.4 which both perform significantly better, and have much shallower DoF + much higher total light transmission than this lens.
(Before the I-don't-understand-equivalence-so-you-must-be-an-idiot-brigade trolls in, let me just remind you that because FF has 4 times the sensor area of m43, then the noise over image area, given similar sensor technologies, are similar when FF uses ISO 400 and m43 ISO 100. ISO is just a number without any real, physical dependence. When equivalent aperture (e.g. f/1.9 vs f/0.95) and ISO (e.g. ISO 1600 vs ISO 400) is used, then noise over image area, DoF, exposure time (or in a word: everything) is equivalent.)
Right, and actually there is exactly one comparable full-frame lens on the market, the Voigtländer Ultron 21mm f/1.8. And of course it is slightly smaller and lighter, and less expensive to boot. Don't know whether it performs better, though.
Nice stuff! But who on earth came up with the 'Edelkrone' brand name? It sounds like a really cheap German discount-supermarket beer. Actually, it immediately reminds me of 'Karlskrone Edel-Pils', which used to be sold by Aldi some time ago for 0.29 € a can (0.33 l), before they renamed it 'Karlskrone Premium Pilsener'... ;-)
Hubertus Bigend: "This marks the first time that the AF system of a mirrorless camera can achieve high performance with lenses originally designed for DSLRs."
No, it isn't, it is the second time. The first was the Olympus E-M1 which does it since 1 1/2 years.
Nevertheless, it is of course one of the several features which probably make the A7R II the most versatile camera on the market today.
And it finally is the beginning of the end of SLT and A-Mount, too, with lenses probably staying in production longer than A-Mount cameras.
@xlabsmedan: Right, but the phase detection technology is on the sensor, not in the adapter... Unfortunately, it now seems that the Kipon adapter doesn't even work with the EM-1 and its phase detection AF at all. They've promised a new version which does, but at least until then I'll keep my wallet closed ;-)
@xlabsmedan: Yes, at least with Canon EF lenses it can, thanks to the recently released Kipon adapter (http://petapixel.com/2015/05/11/kipons-ef-to-mft-adapter-has-impressive-af-speed/), which has been reported to be quite speedy even with contrast-detection-only M43 cameras.
I have in nearly four decades of photography never, ever, aspired to owning a Leica M, because I always found the rangefinder to be a poor kludge compared to the SLR finder, making macro and tele photography impossible, which happen to be two of my favorite fields. The SLR was invented more than half a century ago to overcome the shortcomings of the rangefinder, and the SLR did overcome them, and it was for a reason that it went off on its triumphant course to replace it. Yes, the rangefinder camera could still be slightly more compact with short focal lengths and it continued to exist in a tiny niche, but at no time would I have voluntarily have given away my DSLR for a rangefinder camera.
The Q, on the other hand, is no rangefinder camera, it is a technologically advanced EVF camera, a sophisticated mirrorless system camera without the 'system' aspect. Give me a Leica Q with interchangeable lenses and a broad range of lenses to go with it, and, given the budget, I might be in.
"This marks the first time that the AF system of a mirrorless camera can achieve high performance with lenses originally designed for DSLRs."
It's not 21mm, it's either 14 mm or 21 mm equivalent. This is not nitpicking - with such cameras I expect exact numbers, not implicitly converted ones, just like I would with an APS-C interchangeable-lens camera.
Hubertus Bigend: The cameras are still missing the ability to use exposure compensation in Manual mode with Auto ISO on (which Fuji just added to their X-T1 by firmware update), and configurable factors for acceptable shutter speeds in Auto ISO, too.
Right, some manufacturers label that mode "TAv", some label it "M". Olympus and Panasonic are two examples of those who label it "M", which is what I was referring to. I could have made that clearer. (They call it M for Manual because it refers to aperture and speed only. It comes from an era that didn't have Auto ISO, by the way.)
Hubertus Bigend: I wish Olympus would at least add exposure compensation in Manual mode when Auto ISO is active (and a configurable focal length factor for shutter speeds to be deemed hand-holdable by Auto ISO, if they're at it)...
Exposure compensation in Manual mode has exactly the same purpose as it has in Aperture priority or Shutter speed priority mode – to save me from the need to change ISO, aperture, or shutter speed manually, explicitly. If you don't see the point in having it, you could just as well say "why do you need exposure compensation in Aperture priority mode? You can set the wanted shutter speed manually". Not having to set it manually and thereby being able to react much quicker is the purpose and the reason. At least for someone who's been used to adjust built-in light metering with 'exposure compensation' feature of his cameras for something like 35 years. No, I'm not going to use spot metering to hunt and seek spots that may perchance have just the right brightness to give me the exposure I need, while my object is already leaving the place.
The flash speed limit kludge may give me faster shutter speeds, but what I often need is slower shutter speeds than those I get with Auto ISO.

Koray: Capitalism at its best. After benefiting from decades long hot cash flow from "thrifty fifty" plastic junk, Canon decides to release an updated version. Only because a Chinese manufacturer copied the older version and released it at half price. Not that they care about the customer base, or thrive technological development.
Just cash, my friend, hot cash.
Of course, but the STM stuff will probably be a real benefit, especially when used in Live View mode or on an existing or future mirrorless body.
What we don't know, by the way, is whether Yongnuo might even be selling their replica lenses with Canon's approval - and, who knows, Canon might even receive a small amount for each lens sold. If the lenses were not just very similar, but really identical, I would even suggest maybe Yongnuo had been producing all those Mark II Canon lenses in the first place ;-) (Then again, making them slightly different now may have even been part of the deal...)
photo perzon: Still too largeSome cameras bounce their buit in flash Pana GM1 Fuji X-A1, M1, Sony RX100, etc.
Right, but they're not as powerful and they cannot be used as a macro flash, either. The Metz flash is supposed to be more than just a built-in (or, in some cases, separate, but included) flash.
I'd rather critcize camera manufacturers if their built-in/included flash units don't tilt. Olympus, finally, has done it right with the new flash they include with the E-M5 II. Too bad it doesn't work with any earlier camera.
Two more cons, as far as I can see:
* Remote TTL only as slave, not as master* No high-speed sync
Nonetheless very nice, if one can live with the few disadvantages. And now that Metz' flash and plastics division is being acquisited by German electronics company Daum (and the TV division by Chinese TV manufacturer Skyworth), after having filed for bancruptcy In November, I'd expect their business to go on, too...
