Absolutely will be sharper in the corners at f1.2:
http://www.imaging-resource.com/lenses/olympus/25mm-f1.2-pro-m.zuiko-digital-ed/review/

This is a function of 2 things:
1) Its a better constructed lens than the Canon with almost double the number of lens elements and...
2) It is easier to manufacture a lens to be sharper in the corners on a smaller sensor

Combine those two, and you get the performance you see in the link I sent you.

No, the Canon 35mm f2 lens is not very sharp wide open:

Chris2210: I find it hard to be excited about this lens and NOT to be more than just a bit annoyed.

I'm sure it's a good lens. But let's just imagine this was going to be your principal lens for the system, on an EM1 II. In equivalence terms [yes equivalence DOES matter - it's why you need faster primes for MfT in the first place], it's a 35[ish]mm f2.4. If an f1.2 is always an f1.2, then a 17mm lens is always a 17mm lens - you can't have it both ways. It isn't just a DoF issue either, the equivalence is a sound principle because it also gives a guide to the total amount of light gathered. It's 2 stops in both instances.

Having got that out of the way you can buy 35mm format 35mm f2.0 [yes, not exactly the same - it's half a stop better in terms of equivalence. The Canon EF 35mm f2 IS USM Lens, is substantially less than half the price and what's more it's a lighter, shorter lens.

@Chris2210
The Canon 35mm f2.0 is not a sharp lens wide open at all:
http://www.imaging-resource.com/lenses/canon/ef-35mm-f2/blur/full-frame/

Compare that to the Oly 25mm f1.2 (don't have the 17 yet, but since the designs of the 17, 25 and 45 are all so similar, they will likely all perform roughly the same):http://www.imaging-resource.com/lenses/olympus/25mm-f1.2-pro-m.zuiko-digital-ed/blur/panasonic-gx1/

Also, there are some great, F2.4 Full Frame lenses that are more expensive than this (Zeiss 85mm), and much more expensive than the Canon 35mm--but then again, they are better lenses than the Canon.

Also, the 2-stops rule is a general rule based on THE SAME technology. In reality, it can be more or less than 2-stops between m43's and Full Frame. With Canon as the example, it is much less than 2 stops, and if you use a 6Dii as an example, its more like 1-stop at best:

sportyaccordy: No sarcasm, I don't see why they are stopping there. Give each color channel and luminance an individual module and combine that info. Do away with the Bayer filter completely. Phone camera modules are cheap... probably even cheaper if they are monochrome with lower MPs (since combining them will equate to higher equivalent MPs). But I'm glad to see things moving in this direction.

Because parallax is a thing and it would be quite difficult to compensate for if your sensors cannot be either:
1) stacked on top of each other or,
2) shifted like Oly/Pentax's pixel shift

I wonder if it is possible to create a GRGB 4 sensor square, each with their own lens all slightly tilted to cover the same view as each other. Would likely make the phone quite a bit thicker if its even possible. Plus software would have to unskew the image, likely resulting in quite a bit of softness that might make this whole exercise not worth it at all.

@HowaboutRAW:
You are insane to think that the Otus isn't optically as good as the Leica. Its the highest rated lens on every review site out there. The Sigma is close to the Otus... not as good, but also a fraction of the cost.

Two99: Wow. I come to this site and all there is is negativity.
So for the record I have spent this amount of money on lenses that were not made by Leica. Are they expensive? Absolutely! Are they worth it? Sometimes I would say yes other times not so much.
But calling people fools and idiots for spending their own money on great glass is pretty much uncalled for. If you don't like Leica fine. Some people do like the rangefinder system. So I just don't understand all the anger and negativity. I assume it is coming from the folks from the USA.
I find the prices too high for the cameras but they are a very good, well made piece of equipment. Bought my only Leica in 2013 and I really do love it. The images from it have produced two different exhibitions.
I'm not a fool or an idiot.

@tkbslc
You see its not that the people spending the money are even irrational, because this type of purchase to them is like us buying a fancy cup of coffee. Its really the insanity of our economic system that a few people have such an obscene amount of wealth, that they can buy something like this sight unseen, without a single thought given. This isn't even anywhere near the worst example.

Or $5,500 more than a Zeiss Otus. Or $9,000 more than a Sigma ART 50. Clearly, anyone considering any of this crap has so much money, that its like upgrading your Starbucks from Tall to Grande.

John G Moore: The problem with Surfaces is that they are limited to 8 bit Geforce graphics and an 8 bit panel so they aren't optimal for Pro's who needs a 30bit (10bpc) workflow. MS are going to have a hard time selling Surfaces against this - https://goo.gl/iU5rZG

@Impulses
Yes it is entirely an arbitrary limit due to allowing OPEN GL support mostly on their underpowered and overpriced Quadro line, and pigeon-holing the GEFORCE line to Direct X. Even still, in terms of additional speed to render something, I find that GEFORCE gets the job done faster in most applications simply by brute force.

@John

Ah I gotcha, its tied to overall color depth that can be rendered by the card and shown on a 10-bit screen (which is what the HP combo can do). That screen in that HP is insanely good. Still, I'm skeptical I would notice a difference between an image on that screen that had the full 30-bit workflow versus an image on that screen that didn't. Plus, I'm not sure how useful that is unless you are consistently making museum quality prints of your images. This would not be a requirement for magazine, or other print jobs besides that. I'd personally rather have more horsepower, but I can see the value as a photo editing only tool with this.

Sc1920: If it didn't run on Windows operating system, it would be compelling. Apple certainly has many annoyances, but none of them come close to the aggravation of using a windows operating system and the endless garbage that comes with it. Apple does things that make me feel like trying Windows, but 5 minutes with a windows machine and I know why I use Apple.

@landscaper1
You got it. The day Linux actually makes a full featured OS with product support like Windows, I'd quickly just boot it up on my computer. I'm not married to the Hardware or the OS, I'm married to the software I can use and the cost/features of the hardware--hence my use of Windows-based machines.

@John Moore
Sorry, an NVIDIA 1050 in the Surface Book 2 is much more powerful than a Quadro M620 in the HP you linked. look them up on NotebookCheck. Hell, all you really need to see is that the NVIDIA 1050 is built on 14nm architecture versus the Quadro M620 on 28nm. For reference, the 1050 is 5% more powerful than the Quadro M2200, and the Quadro M2200 is anywhere between 30-50% faster than the Quadro M620.

The CPUs are the same.. they are both current generation Intel ULV processors. Great for low power consumption, but are MUCH slower than standard Intel M-based Mobile processors (like in the Dell Precision line).

In reply to:

tkbslc: My biggest problem with a $1700 fixed lens camera is the resale. At least with an ILC, while the camera value drops like a rock, the lens retains it's value and can be used on newer ones. With a fixed lens camera, the lens has no value.

RX10 III is already $900 used. That's a big hit in about a year.

Agreed. A Panasonic FZ1000 is what, $700 brand new and likely $600 or less used.

In reply to:

Sergey Borachev: It would be great if Sony puts this in their RX10 V or another 1 inch camera. Hopefully, the smaller sensor and a more conservative approach (4 shots only and less MPs) can actually produce more usable images with higher DR, colour depth, and not just very high resolution and huge files.

@Sergey
I'll never really understand why Oly and Panny are set on using pixel shift for color info AND resolution. Just doing color info would make them both smoke all APS-C senors (save Pentax), and compete with some Full Frame sensors. Plus, it will be more feasible to increase the shooting envelope with just a 4-shot sensor shift instead of 8.

User9362470513: I tested the Hi Res mode on the Olympus em1 mk2 with the 12-40 Pro lens against a Sigma Dp3Merrill.

The Sigma DESTROYED the Olympus.

I took a photo of a bookshelf in gloomy light from about 15 feet. The Olympus was good, but the Dp3Merrill picked up individual threads and dust on the glass front of the bookshelf that were just not visible with the Olympus. The Sigma had incredible fine detail of the texture on the book spines, which were just blur with the Olympus.

If you want to take high resolution shots with a small mirrorless camera and you are going to use a tripod, save time and money and try a Sigma Foveon camera.

Strange, since the Oly seems to beat a D810 in high res mode. Also, even if what you are saying is true, you should try shooting the Sigma at higher than 400iso and doing the same test ;)

@BlueBomber

You don't understand how the pixel shift tech works. Oly's and Panny's pixel shift accounts for the bayer pattern by taking 8 shots and shifting the image one pixel to get all the information AND to increase resolution.

Pentax has a similar tech, but they decided (rightfully IMO) to forgo the other 4 shots that increase resolution, and just do a 4-shot pixel shift to get 100% color info ala Foveon. The result is an APS-C sensor with better resolving power, detail and noise performance than most FF sensors.
