Strobist: WARNING!
For any of you that are using software that are heavy on the RAM side, the dinky 64GB maxed out ram on Apples so called macbook "pro" model, is not even close to get the job done.

I.e for composing, the Vienna virtual sample library *alone* (nothing else active) clocks in just north of 140GB in active state (not purged/frozen).

There are still great alternatives from Apple for these types of tasks, the iMac can be configured with 256GB memory, and this is sufficient for performance productions.

I honestly feel that limiting storage at 64GB is both way and far to little in the year 2021 for a "pro" model.

And for you that say "just use diskswap", clearly you have never worked with virtual instruments.

Probably the 2022 version of Macbook pro vill adress this glaring major flaw, and be able to be configured with 256/512GB of Ram, making it a *real* pro 2022 model.

BR Strobist.

Where can you find a laptop with 128, 256, or 512GB of *RAM* ?

Charlie Jin: I think that one of the many reasons why Apple wanted to move to M1
Chip is that Hack’Intosh may not be possible any more (or at least extremely difficult even with the best possible Intel hardware) so that just buying an M1 macbook is cheaper than trying Hack’Intosh.

Apple could not care less about the Hackintosh. They did not even consider it. It is not part of the equation, of the reason to move to the in-house M1. Nobody doing serious work from which their income depends works on a Hackintosh, unless they are complete idiots, and the Hackintosh has never made a dent in Apple's sales.

Antisthenes: Modern, powerful desktop CPUs and GPUs can require, together, /several hundred watts/ of electrical power.
That electrical energy consumed will, ultimately, become heat. Suitably sized cooling solutions — e.g. large radiators and fans — are then required to remove that heat.

For example, for an AMD Ryzen 9 5950X desktop CPU:

... and here's what the radiator and fan combo on a NVidia RTX3090 graphics card looks like:

...so, the "laptop vs. powerful desktop" comparison results shown in this video are quite amusing:

Most of that heat is caused by bad architecture.

Andrey K: How it compares with a good Windows desktop - such as Puget Systems with Ryzen 9 5950X, 128G memory and RTX 3090? Or Threadripper Pro workstation? The price is similar, and for those who do not need mobility that could be the closest Windows machine in performance.

Andrey K, where can you buy than M2 laptop? I cannot find it on the Apple website ;-)

Joe Phelps: I hope this doesn't throw a wrench into smaller FOSS app developers in being able to support new Apple compatibility. Apps like Rawtherapee, Hugin, Siril can be very useful tools, even in pro environments, (as I speak, I am finishing editing a wedding photo set in Rawtherapee, 10/10 would recommend).

However, they have very small teams of volunteers, and have already been hit hard by things like the new Catalina OS with security restrictions forcing them to pay fees to become "authorised installs".

The developers just need to recompile.
Otherwise these apps will run under Rosetta2.

pentaust: My mobile phone does 20Mpixels. I don't spend money on a large camera system for 20Mpixels. 20Mpixels is a thing of 10 years ago. Given state of the art of lenses and image processing / computing power in 2020, my full frame baseline is around 40Mpixels ( approx . 4um pixels). In 2020, I'd never buy a new camera for 20Mpixels, the image results are simply is not worth the money spent on the system (camera+lenses).

Want the versatility of an ILC camera for 20Mpixels images: get an apsc camera, it's quicker operating, smaller and costs half the price of that 20Mpixels full frame camera system.

Remember: 2020 full frame baseline = 40Mpixels.

Dear @Baron_Karza, of course people do that. Most people want to simplify things to just a number, to grasp them better. So, MP. Resolution, both for pictures and video, and also for displaying devices. There are phones with 4K displays, which are a total waste of processing power and battery. People do not want to think, they want simple answers (look at populism, religion, etc). Cameras are no exception.

I would happily take the 20MP of the R6 over the 108MP phones by Samsung. But, hey, 108MP!!!

Right, because the 20mp on your phone have the same quality of a full frame sensor. You are either completely ignorant or a bad troll.

sev7en: It's always a welcome but let me say... R6 looks good but expensive and without any remarkable innovation with what already on the market. I pass, thanks.
R5 is crazy for specs but... What exactly is? Camera for still? Hybrid but camera? Something like a cinema camera?
I mean... This camera is top notch for what? I see it is like a top of specs without really a good engineering.

@sev7en, Just off the top of my head I think IBIS and in-lens IS working together is a remarkable innovation. So there is something wrong in your post AFAIK. 8 stops combined sounds ground breaking. Can similarly priced cameras get 20fps? For the combination of all features the price does not sound expensive. yes, I would prefer the camera to cost less myself. But It is also significantly cheaper than the 5D with a sensor resolution I can actually work better with so...

(unknown member): specs would have been fine in a € 999 EOS RP Mk. II.

but € 2699 ... no way. wont sell a lot in Europe.

Well, xeppelin, they buy a R5. I do not see the point in having a 32" 8K display since one cannot already see the pixels in a 32" 4K display unless one gets very close. And if you can afford a 85" 8K display to put at home to watch slide shows, then the R5 is pocket change for you.

And, well, I do not think the 3218 will go from 4K EUR to 1K EUR in the next 18 months. You are borderline trolling, even though you may not be doing that intentionally.

Xeppelin, just to be clear, why do you think you need more than 20 MPix?

Are you a professional photographer doing portraiture or landscapes?

Do you want to do pixel peeping magnifying the pics like crazy on a 5K screen?

Do you do extreme cropping because you are incompetent at framing?

Do you want to just brag?

I am happy it does not have 32 or 45MP. I want a FF camera, I want IBIS, I want to use my Canon glass. I want to print the pics at a reasonable size (no A2 billboards!). Anything more than 20MPix would be too much for me, a waste of storage and processing power.

nerd2: The display panel is nothing special.. it is sourced by LG display

This does not mean anything. It may be manufactured by LG for Apple but it does not mean it is the same as in a USD 400 or USD 1200 monitor. As for it being "nothing special" please back it up with facts, i.e. data.

apocalypse55: Thank you so much DPreview for this help with Canon ( HOWEVER) the Canon 90D VIEWFINDER focusing ??? Is there a Huge issue with this Model ? I love the Canon system i had 70D skipped the 80D but the 90D will be my next purchase if there's no issue with viewfinder focusing ???

Nothing wrong with Canon's viewfinder focusing. They had a single test and they probably do not know how to delve into the menus and fine tune it.

Azathothh: " Canon's Raw image quality is a hair better than Sony's"

Ouch! Sony fanboys are now in panic.

MikeRan: "No they aren’t. Did you read about the AF performance"

Because they tested with a lens that is know for being slow at tracking.

MikeRan: Clearly Canon did something with the sensor technology here. Yeah, maybe the video performance is the same old Canon but if the DR and noise performance is substantially improved over what they have previously been capable of, then this is big news indeed.

And very good news for Canon..

"Clearly Canon did something with the sensor technology here"

And apparently without going the BSI route. I can only imagine what a BSI sensor from Canon could do.

In reply to:

Nobby2016: DXO is not making it public how exactly they reach the score.

the 1DX MK2 is nearly everywhere better than the D5 and only gets the same score.

what is the reason that DXO does not make it public how exactly they weight the scores?

also DR only seems to be really important at low ISO, why?

sony for example has worse DR at high ISO than canon cameras.... yet sony scores always better at DR.

There is a -8 point adjustment for Canon, simple as that ;-)

Link | Posted on Jun 30, 2016 at 15:24 UTC

ThomasSwitzerland makes a very important point: DxO is a small company and they fight against a giant that has near monopoly on RAW conversion.

But another interesting aspect of DxO is that at some point the quality and robustness of their SW degraded - SW was very unstable, crashing constantly... and they managed to turn around and make their development lifecycle more robust, they even improved the user interface. Their SW is now of much, much higher quality than a few years ago. DxO 9 is a pleasure to use, it is fast, and the quality of the conversion is very high.
