Sigma, PLEASE come up with a FULL-FRAME camera - under $2000 if possible! (Sigma's, compared to Canon, considerably smaller size of) APS-H is still a far cry away from FF.

(Also, while I know we'll never return to the Merrill sensor architecture with its superior color resolution, I do ask for it again.)

Kabe Luna: Apple would benefit from the realization that these are creative tools not art objects. At the end of the day, these things need to be practical.

@dark goob: "So I suspect we will see something modular where the GPU is external (but I pray not built into the monitor). Ideally this eGPU can work with any Thunderbolt 3 Mac."

Given that Apple hasn't ever even tried supporting eGPU's, I don't have high hopes. That is, if it's at all possible to use eGPU's with any future Apple desktop,

- it won't be officially supported
- it won't be hot-plug
- it will require a complete shutdown to be removed (to avoid kernel panic)
- it WILL require considerably hacking - for example, Apple has removed the 9500 drivers from 10.2.4, making AMD RX 480 users' considerably harder.

Mark Banas: Well, let's hope they addressed the overheating/fogging issues as well.

Yup, overheating in 4k mode is pretty much a PIA with the old model. Can't record more than 20-30 minutes at a time; after that, have to wait for 5-10 minutes for the globe to cool down.

Petrogel: So a "German company Porsche Design" has teamed up with industry giants Intel, Microsoft and Quanta Computer to copy a 10 year old (f not more) macbook pro design.
That's good NEWS

@sts2: "Under OS X, it does certain Lightroom processes faster than my Windows desktop which has a much stronger i7-6700K with twice the RAM"

That's because of Windows. Is your desktop Hackintosh'able? The best of both worlds: a kick-ass desktop capable of significantly better results than any Macbook, running OS X.

munro harrap: Its a very expensive executive toy, basically, a ladies powder compact. If it worked adequately you would not also buy a PC would you?

The MacBook Pro with a discrete card and good quad-core processor can replace an i377K unlocked PC, because we checked with mine and it is faster on some things, as long as its plugged in, you dont need a proper PC anymore. At the same price the same cannot be said of the Poor Porsche at all!!

"discrete card"

You can't be serious. Even the best discrete Macbook GPU's are orders of magnitude worse (slower and more inner heat-generating) than even a mid-priced RX 480 in a PC, let alone for example two or three GTX-1080's in SLI...

Yes, I do know what I'm speaking about - this is why I've purchased a Thunderbolt eGPU for my own Macbook...

"one USB 3.1 Type-C/Thunderbolt 3 port which allows for wired image transmission in accordance with the DisplayPort standard"

WOW! At last a sensible PC manufacturer! Now that I have an external GPU, I just *love* Thunderbolt on my Macbook for both image editing / exporting acceleration in Capture One (two-fold speed increase with the RX480!) and, of course, gaming.

Menneisyys: ALL previous Sony Android phones had mediocre cameras. They haven't even bothered putting in OIS. Hope this time they have produced something better. No, 960 fps hi-speed video isn't itself sufficient.

@bloodycape: the lack of OIS in 2017 is plain inexcusable, particularly because for example Apple's implementation is so darned good.

RichyjV: Portable, sleek, high quality screen, and with no dedicated graphics capability you can watch in amazement as it takes a mere two minutes to apply some filters on your 36mp images. For non photo processing needs however, looks quite convenient.

Powerful GPU-wise, too bad these new models don't support any kind of external PCIe connections (via for example ExpressCards or Thunderbolt). External GPU's would speed up a lot of image processing operations tremendously - also according to my own eGPU tests.

"Samsung is a pathetic company when it comes to copying!" - utter BS. You should be happy there are alternatives to the very expensive MS Surface Pro / Book line, essentially driving down prices for us end users.

Menneisyys: The biggest problem with the new Books is the lack of Thunderbolt 3-over-USB-C capabilities.

I've made some serious external graphic card (eGPU for short) benchmark tests (so far, "only" with the latest version (10.0.1) of Capture One Pro), and found out that (at least mid-level) eGPUS's indeed greatly increase operation speed. For example, on my early 2013 15" MBP (i7, 8GB RAM, 256G SSD), exporting the same 125-image iPhone 7+ DNG set took only half the time when eGPU was actively used compared to the case of only using the discrete GPU (the built-in 650M) or completely disabling GPU acceleration. Yes, the higher-quality (faster) the GPU is, the better performance (at least in Capture One Pro) - the measly built-in 650M only sped up operation a tiny bit, while the external AMD RX 480 had resulted in a two-fold speed increase.

That is, eGPU's are indeed very good not only for, say, 3D gaming, but also image processing (and, for that matter, video compression). And how you can connect an eGPU to any machine? Either via Thunderbolt or ExpressCard. Regretfully, both are missing form the new Samsungs. (As do from the Surface Pro 4 / Book, by the way.)

Kimballcorson: For all those fighting the dpreview conclusions on FZ2000 sharpness visa vi the RX10M3, compare the Imatest resolution graphs for the two cameras found on Photoreview out of Australia (.com.au) which very conspicuously shows the same conclusion. The issue really isn't close. You might also check out the dpreview studio and long range resolution comparisons which show the same thing. Such rationalizations.

And traumflieger also had exactly the same conclusion (see my posts below).

In reply to:

Joseph Weissman: Joe Weissman My first impressions with th FZ2500 with actual subjects and not charts were very positive. I am mostly interested in the long focal length performance.

I was concerned when I read the review in dpreview and so I ran my own comparisons with the USAF test chart. I compared with a Canon 400 mm F5.6 on an 80D (unfair, I know).

Procedure:

indoor distance of 20 feet,
tripod,
shutter delay,
ISO400,
manual focus/ live zoom.
raw converted DNG
view/PS.

The canon prime is sharper but not by more than 2 steps on the chart, a 10-20% difference. Both images were in the 50% range of the Nyquist freq.
70% to the edge og FZ2500 sensor at 480mm , it is 15% less sharp.
There is greater loss with jpeg in the Lumix than the Canon.

My conclusion is that the Panasonic lens is pretty sharp. I am wary of comparisons with jpeg or with outdoor shots during full daylight at long focal lengths. Heat shimmer varies between shots, also.

I'll post my images when i get time.

@marshwader: "it's also possible that dpreview just ended up with two bad copies for one reason or another"

I don't think so - this is a generic problem also emphasized by other reviews and comparisons. The Traumflieger folks, in their December review, have also concluded exactly the same regarding lens quality and its relative sharpness compared to both the FZ1000 and the RX10MkIII. That is, unfortunately, the FZ2000 indeed has an inherently soft lens.

Here's the review URL (German):

nerd2: Stereo craze has passed by decade ago....we already have cheap rgbd sensors

@otto k: "On the other hand, I had no issues with LG G4 vs Note 5 in simple Fiit VR (aside from the obvious AMOLED vs LCD differences)." - the official Oculus support puts Samsung's VR implementation in a whole new dimension, compared to anything else mobile. We have a playstore with some excellent games - for example, GUNJACK, an excellent title where the, compared to desktop VR, inherently lower CPU / GPU performance don't show. We have a full-fledged game selector menu with built-in image / video viewers, Web browsers, Settings accessors etc.

All these are missing from other (non-Samsung VR-compliant) handsets.

@otto k: you meant my post on the Samsung? That is, the lack of my mentioning Sony's existing 4K phones? There's a reason for that:

- complete lack of dedicated (with Samsung, even official Oculus!) support
- generally worse-quality handsets than those of Samsung - for example, the IQ of the camera.

This is why I don't even bother mentioning Sony when it comes to mobile VR.

falconeyes: My concern with 4k VR is that resolution creates a toy-like experience.
Tried it, after first curiosity is satisfied, becomes boring very quickly. Won't take off commercially.
4k VR leaves 420px per 50mm-lens equivalent viewing width. That's very pixelated and requires 8k to be pleasurable. VR will take off with 8k though (840px or DVD like experience).
Moreover, 8k VR headsets (100 degrees FoV optics) require 5k smartphone screens (or a corresponding dedicated VR headset) to display. Both is a decade away for mass market penetration.
So, the next 3D hype will be it. Not this one. Or the one before created by the Avatar movie.

P.S.
Small 180 degree fisheye lenses resolving 4k tack-sharp edge to edge (which 8k VR requires) will be another challenge ...

"So, it would make a difference for 4k 3D content (non VR) but that line of development has silently died for some reason (motion sickness?)." - you mean the demise of traditional 3D TV's? The reasons are well-known: http://www.dailymail.co.uk/news/article-2765862/Why-3D-TV-proved-turn-Massive-investment-1-5-million-sets-sold-persuade-great-British-public-wear-silly-specs.html

I, who have watched one or two feature movies entirely in 3D on my Samsung S7 Edge + Gear VR and also tested 3D video playback on the HTC Vive (that is, using VR helmets), personally liked what I experienced. No motion sickness, no headaches. It's "only" the resolution that was problematic; this is why I stated 4k (and, in the more distant future, 6/8k) will be a big step ahead from the current 2...2.5k screens.

"VR 3D leaves nothing but your jaw dropping" - definitely. As soon as (hopefully in H1 (via the Samsung S8) of this year) the resolution of the screen is bumped to at least 4K, meaning 1920*2160 for each eye, they'll become a great way to watch 3D videos / movies.
