Alphoid: I'm wondering how much the 0.77x crop factor does for you, relative to economies of scale and the type of engineering that goes into a modern, high-end mass-produced dSLR.
I'd love to see an actual, objective comparison to a D800 with a nice Zeiss lens, a Sigma 35mm f/1.4, or similar. 35mm lenses have come a long ways since the days when I last saw someone compare MF to FF.
I hear all about the magic of MF, but I wonder if at this point, it is still real or just psychosomatic.
You can read here an interesting comparison between the Nikon D800E and Leica S2-P:

It sounds almost ridiculous when someone says in 2014 that CMOS sensor is a "major leap forward in camera development". In 2000 the Canon D30 already had a CMOS sensor! That is, the sensor technology of medium format is lagged 14 years compared to other formats. The technology in the MF field develops so slowly that in 2028 Hasselblad (if it survives until then) will be bragging that its MF cameras can shoot 1080i video…
@ Andy CroweNote that there are backs for MF format with resolution as low as 22 MP…In my opinion, what characterizes the MF format is not exactly the sensor resolution, but the quality of the lenses. However, with 35mm cameras with 50+ MP sensors around the corners, and the emergence in the market of lenses like the Zeiss Otus, Sigma Art, etc., the so called MF format has an uncertain future.
Why do you think the amount of MP is so important? Do you know that you can buy a 41 MP Nokia Lumia 1020 for only $ 99.99? And that the Lumia 1020 can record full HD video, something impossible with a Hasselblad? Finally, before you start to disparage the Canon D30, please tell me how many MP a Hasselblad had in 2000…

Frank_BR: For every "pro" shooting with a Nikon D4S at ISO 409600 ISO, there will be 4096 amateurs with a P&S or smartphone shooting at ISO 100. Do you understand now why Chicago Sun-Times fired the entire photography staff last year, to just rely on freelance photographers?
It should be clear to everyone that the most important social events are now better covered by the participants themselves than the traditional press, since almost everyone carries a PS camera or a smartphone. Consider, for example , the dramatic events in Kiev, Ukraine. Have you seen the photos? Tthe vast majority of the photos and videos that will remain as a record of this historic moment, were taken by PS cameras and not by Nikons D4 or Canons 1D.
The PS cameras and smartphones are great for journalistic coverage because the IQ of the small sensors has reached an excellent level, much better than of a ASA 400 Tri-X film, which was widely used by photo reporters in the twentieth century. Furthermore, the small focal distance of those small-sensor cameras ensures a great depth of field, so that the pictures are always in focus. Last but not least, smartphones allow instant transmission of the photos, something that a "professional" D4 doesn't.

Why are the camera manufacturers complaining now? In 2009, 2010 and 2011, the world sank into recession, but the sales of cameras were peaking. Then the world was becoming poorer but camera manufacturers were making money like never before. Was that fair?
Now that the economies of the USA, Europe and Japan are beginning to recover, the sales of cameras are running out of gas. That old book would describe the situation, saying that fat years are coming to the world, and lean years to the camera manufacturers. Isn't that fair?
Most likely, any reasonably capable Japanese optical company can make today a virtually perfect 35mm lens, especially if the aperture is a modest F2.8. Indeed, except for the high price, this "Zeiss" lens does not seem to be an authentic Zeiss, but a Japan-made lens with a Zeiss tag.
The question is, why Sony charges a reasonable price for the cameras, but so much for these faked Zeiss lenses?
In the near future, the prices of FF entry-level models should fall below $1000. Then, it will be clear to everyone that today's prices of most prime lenses are too high.
Frank_BR: It seems that there is a lot of interest, but little information available about how these cuts in half are made. I believe a viable technique could be using what is called "wire saw", where a metal wire impregnated with an abrasive powder (diamond, for example) slowly cuts the workpiece. More information here:

Frank_BR: The Kowa 8.5mm F2.8 is an ultra-wide angle lens with a distortion of only 0.12%. Remarkable!
However, many m43 cameras, Panasonic in particular, use distortion correction by software, so that quality of the Kowa 8.5mm is not very relevant in practice.
For all I know, the GHn cameras do distortion correction even for video, but only when Panasonic/Leica lenses are employed.

I noticed that all the four guys from Nikon wear glasses. In contrast, the executives at Fuji, Sigma and Sony who were interviewed at CP+ 2014 do not wear glasses. Does this mean that to be an executive at Nikon one needs to be nearsighted?

A Zeiss Otus cut in half has an effective aperture equal to 2.0, that is, the loss is a modest one stop. On the other hand, I suspect the bokeh becomes horrible...
I have the impression that there are much more Sony A7s working behind legacy lenses than behind an expensive Sony / Zeiss FE lens. Certainly there is a great opportunity for Sigma, Tamron and Samyang flooding the market with compatible FE lenses.
Size-wise the Sigma dp2 Quattro is a giant. Indeed, it is wider than a Nikon D4! It is even wider than a medium format like the Leica S!
On the other hand, technically speaking the dp2 is a dwarf:1. Maximum shutter speed: 1/2000s2. Maximum ISO: 6400*3. No video4. No interchangeable lenses
(*) The low maximum ISO is a strong indication that the dp2 sensor is noisier than the traditional Bayer sensor.
edvard s5: For me design is simply genial.Imagine how nice it fits to the inner pocket of a jacket, the grip stays outside, you need not to push the whole hand into the pocket to get it out, :). Very fast for every day/street photography.It seems there is a lot of space for camera designers left.
>It seems there is a lot of space for camera designers left.
What about a belt holster? :)
This is not a serious camera. It seems more like an attempt to draw attention. The real business of Sigma is manufacturing lenses.
Frank_BR: LensTip has tested the Nocticron and the resolution numbers they got are simply phenomenal. Compare, for example the corner resolution MTF50 for the Nocticron to other first-class lenses:
Nocticron 42.5/1.2 @ F/1.2 – 47 lpmmCanon 80/1.2 @ F/1.2 – 20 lpmmZeiss Otus 55/1.4 @ F/1.4 – 28 lpmmLeica APO Summicron 75/2.0 @ F/2.0 – 24 lpmm
> 4/3 requires DOUBLE LP/mm of FF lens
Even if you divide by two the resolution of Nocticron, it still beats the Canon 85/1.2, virtually equals the Summicron 75/2.0, and is only a little worse than the Zeiss Otus. Remember, too, that the Nocticron is 1/2 stop faster, has AF and IS, is much smaller and lighter, and costs only 1/3 of the price of the Otus.
According to LensTip the edge resolution of the Olympus 45/1.8 is 46 lpmm @ F/1.8. This number is excellent and on a par with the Nocticron but at the much larger aperture of 1.2. However, remember that it is infinitely more difficult to design a super-fast lens with aperture 1.2 than a lens with aperture 1.8.
