Just ask and they shall do it for you! But of course, you will have to buy at least two cameras to gather all the features you need, since omitting feature is a commercial trick to cover more market.

Funny Canon rep confession: (http://www.slrlounge.com/canon-rep-looks-back-dslr-video-revolution-couldnt-funnier/)

For me, I finally went the Sony A7R route for landscape photography and couldn't be happier. Combined with very sharp lenses from other brands, and image stitching, this 36Mp CMOS beats anything I have seen from Canon so far and flirts with MF systems.

OBI656: CaptureOne is a great application for pro photographers however to install CaptureOne and specifically do an upgrade it is absolute pain.

I have NOT seen application in history of Mac computer being so terribly difficult to install and upgrade.

Why they are doing this so difficult for end user is beyond to comprehend.

Perhaps at least some of the difficulties you are experiencing come from the OS. I'm told that if you don't perform a clean install of Yosemite and a fresh reinstall of all the programs, but use the older system files with the migration tool, you are heading all sorts of subsequent problems, some of them nasty. That's why I am holding to OS-10.8 and CaptureOne 7 for as long as I can.

I wish they had made it compatible with Mac OS-10.8. I can't keep up with Apple's constant changes.

d2f: Referencing the comparison table above: Can someone tell me in detail what "self cancelling" means under optical low pass filter for the 5DS R?

It looks as though the 5dsR RAW samples have been withdrawn, but Imaging Resources still have crops of the JPGs from the beta prototype in their test and review page. Comparing AA cancelled 5DsR to no AA Pentax 645Z and Nikon D810, is edifying. However, they mention that better detail should be attainable with proper in camera sharpening settings (RAW or JPG only?) and with an optimized RAW converter. So let's wait and see.

Some JPG samples from 5DsR are now available on Digital-Imaging.com. RAW samples can be downloaded as well, but none of my 5 programs can process them at the moment. They are in camera JPGs, but it's edifying to see how they compare to their Nikon D810, Sony A7R and Pentax 645Z siblings. It looks to me that image size put aside, the Sony 36Mp CMOS pulls out just as much information, with leaner files.
The next big step in Full Frame image quality will come from the 50Mp Sony A7RII, which is to be announced very soon. Another sensor technology and definitely a better option for landscape photographers.

That is likely correct. One way to be convinced of the ill effect of the AA filter with effect cancelled is to download RAW samples from Imaging-Resources.com, and then to process them with identical parameters in a side by side comparison. I did this for the D800/E/D810/Sony A7R/Pentax 645Z. If you watch an area where clarity is obvious, like the Greek bottle sticker, the difference between with AA filter, AA cancelled and no AA is very obvious. If then you add the 7DII sample in the comparison, you understand why the 5Ds/R samples had to be over-sharpened to look sharp. It's like placing a blur filter in front of the lens and later trying to regain the clarity by means of algorithms. It thickens the edges but does not recover lost patterns. …My 5 cents.

alpshiker: (…) Will the 50 MP be useless? They will certainly be precious when it comes to re-framing and cropping into images. Those cameras will be awesome tools for wedding photography for instance, and even some portraiture style, every aspects where a soft and very subtle haloing effect is a welcome feature. But for landscape or architectural photography, both miss the point. How many years will we have to still wait for a mature, well thought, non AA filtered 50 MP Canon camera? Nikon learned the lesson well and developed the D810 with no AA filter as a successor for the D800/E.

I was trying to be kind to Canon when I wrote that. Not only do we need good glass, though many of Canon's L series will already benefit from higher pixel counts as they are, but we need a CMOS that can do justice to the resolution. I'm sure Canon will eventually get there once Sony will have paved the way, but for now they are still under threat from medium format systems manufacturers. Take that with a grain of salt!

(...) LightRoom includes a moiré removal tool. Also, the higher the pixel count, the less prone to moiré the sensors are. So there is still room for a better camera in an upcoming (?) AA filter free Canon 5Ds à la Nikon D810.

I dug into this myself some days ago...
To avoid moiré phenomena, manufacturers place on the surface of the sensor a device called an optical low-pass filter or anti aliasing filter. It consists of a blade of a material having birefringent properties. The slight blur produced by the diffusion of the light rays prevents moiré. In the low pass filter with effect cancelled, a second blade is oriented so that it will invert the effect of the first blade and "to some extent", cancel its effect. This technique allows manufacturers to keep the same arrangement of the sensor in different version of cameras (800 / 800E, 5Ds / 5DsR). The problem is that there is a slight degradation of the image quality (haloing and false colours in highlights and shadows) resulting in less clarity. Anti aliasing filters are perhaps useful for HD movies and JPG shooters who don't want to edit their photos, but high end photography can live without. Most medium format backs have none, the Nikon D810 has none. (..

Well, the 1Ds series used to be Canon's flagship cameras, with regard to image quality. The 5D's II and III were essentially functionality oriented upgrades, but sensor-wise, we haven't seen anything significant since 2007. That's what I meant by 5Ds being the next upgrade. I gather from Canon's statements relayed over the Web that there should be other iterations of the 5Ds, which makes me think that hopefully one of them will be specifically targeting applications where maximized clarity and acutance are sought, such as for landscape photography. But this will probably take another year or two, which as a faithful Canon user really pushes my patience beyond what is reasonable.
