Dimit: So much trouble for m43 ???
Olympus makes great cameras but nullifies itself by not upgrading to ff.
Pitty..

"[...] where else a FF is usable anywhere, anytime, any condition."

Silly. Very silly indeed. FF is usable only in the places and times where/when carrying extra 2-5kg of gear is OK. And in the places where it is allowed to have a pro-looking camera with you. And in the places where taking out your huge camera would not spoil the mood. Basically, only if you have no life, never leave the house, only then the FF is "usable everywhere, anytime".

"m43 is a compromise for portablity and it'll always be."

Which is quite important and not to be underestimated for an inherently portable tool which a digital camera is.

Raist3d: Richard, something is not quite right with this explanation of the high res mode. We were just discussing that over the m43rds forum and the point was brought forward.

Think about it- if you are capturing full color in a spatial position, that gives you an original "Foveon X3" type file of 16MP. If you shift a bit to then do the 4-position dance again, that at best gives you another 16 MP file. So the total is really 32MP, not 64MP, or even 40 MP.

My guess here is that Olympus is doing a clever analysis that gives them the near full color data and bump up to 40 MP. Makes even more sense why it's 40 MP and not 64 MP. The 64 MP file does not seem to me would be full spatial resolution. It also keeps color moire at bay.

And to finish the merge, and get the 64MP image, one simply mixes the color channels of the two images taking colors from the overlapping pixels of the two 16MP images.

What I'm relaying here is of course a generic algorithm I have just "invented", using the 15yo knowledge from the computer graphics classes I took at university. I'm sure that Olympus has imaging experts who can do much much better with all the information available from the 8 shots.

"My guess here is that Olympus is doing a clever analysis [..]"

Raist, it's not "clever", there are old and tried methods in computer graphics dealing with that kind of things. Effectively it is an interpolation.

For information interpolation, you have to stop thinking in discreet units, and go for rational/fractional units. In this case one can simply multiple/divide by two, but since it is 2D image, the factor of two becomes factor of four.

First four images taken, with the steps at 1 pixel size, turn the four Bayer 16MP images into one 16MP true color one, as you say.

Second four steps do the same - but with the step of half pixels. Another 16MP true color image.

Now, we need to merge the images.

Visualize the image as a grid of pixels. Now overlap the two 16MP images/grids, with offset 0.5 - what would you get? Every pixel in the first/second image is cut in *four* parts by gridlines of the second/first image. 16MP * 4 == 64MP.

In reply to:

Donnie G: Seems to me that these 2 new Canons have the potential to further disrupt the medium format market and possibly in a major way. It just seems like a good bet that up and coming architectural and fashion photographers would find a lot of uses for these cameras and their L-lenses that were not possible or even affordable to do with traditional medium format gear. Don't be surprised if Canon winds up taking some serious marketshare away from the medium format makers without having to invest in designing a MF sized body or MF lenses and lens mount. :)

"The 5DS will convert many others still clinging to their MF backs."

IMO, if D800 didn't manage it back then, I doubt 5DS would fare much differently.

Difference between 38MP and 50MP is relatively small.

While the price difference between a used D800 and a new 5DS is huge.

It seems that the people who wanted to move from MF already have. But the remaining few indeed need the MF, and as such are unphased by such releases.

In reply to:

DStudio: Why create a 50MP sensor and then "pre-blur" the image with an AA filter? The applications for the non-R model seem rather limited.

> "Fake Detail" sound like something a Canon loyalist would come up with

It is something used by people who actually understand intricacies and inherit problems of the demosacing algorithms, required to make an image off a sensor with layout, Bayer or X-Trans.

Mssimo: I think this will be a very successful camera. Sony/Nikon/Pentax/Fuji/Olympus/Panasonic photographers have been spoiled with crazy dynamic range but canon shooters know how to optimise the exposure to get the best image possible with 6 year old sensor technology. The big issue with this camera is the price in six months. Nikon and Sony will have 50MP+ super sensors out this year. Those cameras will retail for much less than $3700 US. Canon has great lenses and great body (other than sendor) quality but its time they give in and let someone else create the sensors. The best way I can put this is: Canon is a beautiful, long haired, tan, big eyes, long legged, charming girl with brittish austin powers teeth.

> canon shooters know how to optimise the exposure

"Optimize" means that you sacrifice abundance of something to compensate for the lack of something else. And more fiddling with the settings. Compared to the competition, sensor doesn't give much leeway to sacrifice something.

In the end, Canon shooters may know how. But I doubt many take any pleasure in that.

ThePhilips: Oh. The top LCD.

Another thing I stopped craving, after I went with a mirrorless.

I'm not sure why NX1 has it. Probably because Samsung could do it, and some DSLR users are are simply hanged on the fact that the top LCD is a mark of a premium DSLRs.

Simple truth is that a mirrorless camera doesn't need top LCD. More information is, of course, better and extra display doesn't harm. But all the information is already readily available on LCD and EVF.

The top LCD is a crutch for DSLR where it is still often impossible to have customizable info overlay on LCD and EVF.

bosco1955: Why not going the other way on the ISO....25,50, ?

"Why not going the other way on the ISO....25,50, ?"

Sensors have limited sensitivity range. Last time I heard - 4-5 EV stops. That range is then stretched by electronical and software tweaks to cover the needed range if ISO numbers.

To improve the high ISO performance, low ISOs gets sacrificed.

High ISOs are hard to compensate for, while the low ISOs can still be compensated for by (unwieldy) ND filters.

Timmerdude: After more then 40 years of use Canon products I moved to the Panasonic GH4 because of video.
Canon is not listening to it's customers.
They will be losing more and more customers!

Wait for how long?

Why wait?

YOLO

Miles Lye: If Sony can get IBIS and exceptional high iso performance in the A7RII, then what's the point in upgrading or considering this camera or a Nikon alternative? Why pay more for less? The A7 cameras aren't perfect at all but Sony is making amazing progression in a short amount of time and they listen. After using an A7 and seeing the progression with the A7s and A7II, I don't doubt Sony will make this camera look dated when the A7RII is announced.

"PLUS, the Zeiss lenses for Sony mounts (A/E/FE) are all AUTOFOCUS."

STOP SPREADING THE LIES!

Zeiss Loxia, from the product page: "Revel in the exceptional feel of precise manual focus [...]"

Whole bunch of Zeiss lenses are MANUAL FOCUS only.

But I do not blame you for the confusion. At the price, nobody actually owns them to see what they really are.

Esign: Quotation from the Swedish yacht designer Peter Norlin (1941-2012): “When someone shop for a sailing boat, they look for a very slender and graceful exterior, an extremely roomy interior with full standing height everywhere, and they want it for free”.

And your point is?

The most popular opinion expressed here is that the lines are not so slender, and there is nothing graceful about it.

And it costs more than the one in the neighbor shipyard of competitor.

nicolaiecostel: I hear this again and again and it really bugs me. Pretty please, explain why a wedding photograper need 50 MP ? I shoot weddings since 2008 and I'm perfectly happy printing 25x50 cm album spreads from the 12 Mp D700 or 70x100 cm wall prints. Why on earth would I buy a camera with huuuge file sizes, not that fast, not good in low light and with bad DR, instead of a camera like the D3s/D4?D750/5Dmk3 ?

@nerd2, LOL. Weird choice of language. Do you satisfy your clients with a camera? What lens do you mount for the occasions? :)

Anyway, most displays are 2MP and only now barely reaching 4MP resolution-wise. So, a good 5MP shot would indeed look good to the customer. Because 5MP is still more than 4MP.

4K (8MP) displays are still very very rare among pros and virtually non-existent among customers. But even then, the displays either very huge or have very small pixel. 5MP would still look OK on 8MP because of either viewing distance or the inability to see every individual pixel.

qwertyasdf: If it's really aimed at landscape / studio work, why they don't add a swivel screen?

I can even do a selfie, 50 mega pixels of myself!!!

@Seth, many Olympus cameras (span over decade now) both are weather-sealed and have swivel/fully articulated LCD.

The things are not mutually exclusive. And it was done before many time.

It's just Canon decided not to do it.

I thought they would be at least smart to include 4K to go along with their new video-optimized AF system. I was wrong.

Sirandar: Comparing the standard res Mark II images to the original OMD E5, they just don't look as sharp or crisp with the II. Am I missing something? Look at the green feathers...

Also, the addition of a articulating display is very welcome, but can you turn the display to face inwards when not using it? Since even with a screen protector the display tends to rub against stuff and take damage, turning it in would make shooting a much more carefree experience.

My old Pana FZ30 had this feature and I took advantage of it a lot as I tend to use the viewfinder.

@Richard. How can I know why? This is not the first time complaint about blurry shots with the Oly 45mm is raised. And this is not the first time you simply brush it off.

I understand that the studio scene is a lot of work. Which is even more reasons to use the best lens available. And yet.

In reply to:

brycesteiner: The studio shots on the new E-M5 Mk2 appear to be very out of focus for the standard. Was it shot poorly or has Olympus added no sharpening...?

"Given there are only two 45mm primes for Micro Four Thirds and the Olympus one out-scores the Panasonic/Leica Macro in DxO's test [...]"

Oh not this again. DxO numbers for m43 are at best inconsistent. Just compare the GX7 results with the GM1. The two have same sensor and thus should have the same results - and the same lens resolution.

DxO lens/camera scores for m43 are inconsistent at best and should be simply ignored.

"I'd question the 'poorest 45mm' statement, too."

This is pretty much unanimous conclusion of pretty much all users who handled more than one of the lenses, which was reported in many different posts and blog articles, esp recently after the release of the 42.5mm. The rating of the lenses, from best to just good: (1st) PL 1.2/42.5mm, (2nd) PL 2.8/45mm, (3rd) Oly 1.8/45mm. The Oly 2.0/50mm resolution-wise is up there with the 42.5mm.

Thus, yes, Oly 45mm is a "bad" lens, when compared to its near perfect peers.
