On article 4K video: What you need to know (282 comments in total)

errata: 4k (8Mpix) contains 4x the pixels of 1080p (2Mpix), not "twice" as posted.

This may be about content, trackable edits, archival mgnt. and practical speed (of 'processes').

However unpopular Reuters' decision might be, it's IMHO positive. Because we got lazy:

1) Some camera makers don't feel any real pressure to improve their image processors and OOC JPG, when their most discerning users couldn't care less (since they're hooked on a RAW/LR workflow anyway). And the consumer segment can't tell the difference between great and mediocre OOC JPGs, given their cheaper screens and other practical factors.

2) We as RAW shooters got lazy as well, knowing well that today's sensors DR and noise characteristics + post-tools can fix nearly any exposure time issues. Those 13-14 steps of DR + the LR magic can literally salvage most botched shots and still produce spectacular results.

Perhaps Reuters wants less 'magic' and 'spectacular' RAW results, in favor of a simpler to produce, store and audit JPG (with much less tolerance for error at shoot time)?

OneLeggedCat: That interface, like Google+'s, is atrocious. Google's relentless drive to dumb down its products so that a 2-year-old can easily use them means that only 2-year-olds may eventually want to. Also seems no practical way to control the presentation/organization of the photos to your intended audience. All that gimmicky combination of photos into movies with crappy music is annoying. The whole thing seems kind of useless, except maybe as a photo backup service for people who don't really care whether their photos are backed up anyway.

see the involution of gmail, and recently Maps: Perhaps the 2-yr-olds like them now, but we all lost something i was willing to pay for... While we have solid alternatives to gmail (also private), google's maps and streetView were hardly matched by Bing - this gap has no OS substitute yet.

Picasa is going down the same road, but as with gmail, no worry here - we have plenty of alternatives.

Akpinxit: really bad idea for walking through crowd

Not only thru crowd... The repetitive extra shocks (measured in g's) and vibration is potentially damaging for the optics and mechanics alike.

Can one walk fast, trot, not to mention RUN, for any extended periods?

Most often i walk/trek 20+ miles/day with camera in my hand, or bag.

I wouldn't dare it with such cowboy outfit :-)

Frank_BR: The mirror mechanism is as complicated as the tape transport mechanism of a VCR. It's good that Canon starts thinking seriously about launching a professional mirrorless camera or it will have the same fate of the VCRs.

Mirror-based OVF vs. mirrorless is a salient point of comparison and camera design. It deserves much more attention from the camera design and from the testing communities.

For mirrorless with live sensor one has to deal with different readout and ADC circuitry, higher operation temperatures, different noise profiles (2 of the 3 noises, google and wiki around for details). And naturally, the associated issues and merits of EVF.

Ditto for mirror-based OVF, whose merits are obvious to most of us... reason why still used 1/2 century later. Add the less obvious merit that it can also keep the sensor cooler (those noise profiles), avoiding the optional (in an dSLR) 'live mode'.
The demerits of a mirror system are also qualitatively obvious, though we need more quantitative comparisons at 36-50MPix resolutions.

All in all, this comparison is worth objective, non-partisan investigations and reviews, untainted by our preferences.

Yiannis A - Greece: Dear friends,
every day i wake up, i take a look at a yellowish, faded, rough picture of a bunch of young soldiers, somewhere in the Greek-Italian front at the end of 1940. Amongst them, i see a laughing 25 year-old sergeant, smoking his cigarette. The only thing i feel is, how much proud i am that i've been raised by such a man and how much i miss him. But trust me, i've never thought "grandpa, you look so poor in terms of dynamic range" or "oh my God, such a luck of color depth here"!
Photography should not be a way of comparing our wealth, taste, stupidity or whatever characterizes us; photography is a tool that must be wisely used to prevent the soul, the heart, the brain from forgetting, after times have passed. Don't fall for DXO and all paid advertisers, stop being mean to each other. Buy whatever camera you like, whatever instrument you can afford and just shoot. Frame the moments you live and keep them alive, forever, in the hard disk of your soul.

Be well, be lucky

Indeed, in the grand scheme of things most of what we so ardently argue on these forae doesn't make any difference - certainly not outside this tiny community on a planet at the fringe of a galaxy.

Even stronger one should agree with the need for more civil and factual dialog, vs. the sometimes overly visceral reactions that somehow seem to prevail.

Alas, here we're ardently impassioned about our gear, tech and the performance thereof. It's only human to care about such triffles and strive for the better. Seems to make a difference to some of us... Again, agreed about the want for a more civil dialog.

+1 for high dpi color e-ink

What a delight would be to have 300+ dpi e-inks in 10" tablets and 22-31" flexible/foldable displays... I wouldn't care about gamut, speed, video... just slow and sharp static content!

Alas, eink is since long a monopoly and e-readers a niche/fringe market, with glacial pace, high prices and low IQ - even the latest Kindle Voyager is a tiny B/W medium dpi device !

ShadowVlican: glad they are mentioning GAMUT... this means more consumers will know what it is and finally look for this spec when making decisions, which in turn forces manufacturers to compete in this arena (which hasn't been done yet)

Glad to hear about wide gamut!
However, 99% AdobeRGB is not impressive in '15, when my '10 arguably cheap ZR30w had measured (not spc'ed) coverage 111-115% AdobeRGB

UHD will hopefully improve on today's gamut, and lead to at least 10-bit workflows. E.g., no 3-4K laptop today can output a 10b stream, mainly because Intel's video buffer is chopping Nvidia's streams back to 8bit :-(

High dpi per se is absolutely good and desirable, particularly for my tired old eyes - i loved 4K displays on 22" since the dot.com blast...

What's wrong is the OS and app font scaling, still prevalent.

However, i can't wait for wide gamut 8K displays, be they 31" or 22". Photos, fonts and graphics are sharp, pixels are invisible, jaggies and aliasing effects gone. Just proper scaling, please Adobe, MS et al. !

Nice shots, some have serious labor behind them..!
My picks

3: Drama of the primeval forces that have shaped Earth and brought life upon it.
5: Painting-like, albeit too cropped on the LHS (probably for a good reason).
1: Street-like shot for the venue... the lions seem not to bother anymore about drones (noisy!), except the 2 cubs. Perhaps they see more drones daily than us :-)
4: Weird background, is it a museum canvas shot - or why the shades?
2: Interesting composition.

marcio_napoli: Typical DP review crowd. They all look for specs, actually knowing very little how to use it in the real world.

It's just about numbers, on gear heads minds: DR numbers, MP numbers, ISO numbers, and now, 2k vs 4k.

In just a few years, 4k vs 8k... numbers, bla bla bla, numbers.

If my statement above doesn't cut it, the mighty ARRI Alexa is a 2k camera only.

Do you know what the "obsolete" 2k Arri Alexa means to the movie industry? It's basically the most acclaimed digital movie camera ever.

And guess what, few, very few Hollywood level movies are actually produced in 4k.

Very, very few.

If Hollywood is not ready yet for 4k, do we really think a bunch of gear heads on DP review are really in THAT need for 4k ?

Oh dear...

Why bother then buying 4K TVs and projectors, laptops and tablets , 4-5K monitors (from $600)?

Practically all the medium to high end display devices today in production are 4K and above. People are buying them already...

Content rules: Sony had since '13 limited 4k content delivered by HDD to their projectors's customers. Ditto Netflix, Vimeo et al. are streaming 4k content over 15Mbps lines.

A pro-level cameras scheduled for '15 can't even shoot basic 4K - because art must be shot conservatively, with last century's golden tools of trade?

Thanks! The results above are quite typical for the newer Sony sensors...

One would expect Canot to play in the same league... if not leading, like a decade ago. In stead, i expect that Canot will try to leapfrog Sony/Nikon, Fuji, and Samsung with 2-3 heroical efforts... and eventually do like Nikon... by that time having lost a big share of its pro niche.

KAllen: At Canon we see impossible....then give up.

A ship of Canot's size can NOT turn around too fast... for the same reason, nor can it go bankrupt after merely a few bad years...

They command too much market share and branding power (on which they rely) to succumb over night. And then thay've still got lucrative niches, e.g. the pros, whose expenses are tax-deductible. Here the margins are arguably an order of magnitude higher than the Rebel's.

irony aside, probably Canot will try stalling the game some more... E.g., by again reusing their ancient CMOS in 'innovative' ways: Overlay / multiple stacked sensors (pseudo 2.5/3D stacking), hybrid sensels, new column ADCs, new ulenses etc... all perhaps in the same 40+ nm CMOS fab predating by 3-4 yrs. the Lehman Bros financial collapse :-).

Will take care as before NEVER to compare (or even mention) their antiquated CMOS vs. the current 14/18nm generations... don't ask, don't tell ... :-)

Direct link | Posted on Oct 14, 2014 at 18:59 UTC

The visceral response against Canot's negative campaign (about no product, but a marketing campaign...) => this audience has little tolerance margin left for Canot, particularly after the Masaya-san "we're the best" interview.

Perhaps Sony or Fuji could've gotten away with such negative marketing blunders, given their recent record tracks of actual innovation. Yet Canot certainly not, as shown in ca. 1.6K flames here...

Net effect on my own future 'roadmap' purchasing decisions: Focus on the Sony and Nikon (FF) mounts. Keep an eye on Fuji's X-series. Relegate Canot to P&S A-series for family and birthday gifts; avoid a future investments in their mounts, however large and inviting they seemed to me a decade ago.

Thank you, Canot, for eventually sorting it out for me! (- after a protracted dilemma "what if later they change ...?" )

Canon's new campaign is negative, in fact it's overloaded with negativity more than any social networking mood manipulation experiment (worth a google).

Little wonder its 1500-strong feedback on DPR in the same vein, NEGATIVE, and the ill-will this marketing experiment has generated: One harvests what one's has sown...

Canon has broken into new territory, together with breaking the rules #1, #2 and #3 of marketing: Always adopt a POSITIVE, CONFIDENT, CAN-DO!

Canon, pls. address the critique not by words and counter-arguments, never by contempt or denial, but by constructive proof to the contrary: Scheme, method solving the issues => Product!

If Canon's CMOS fabs are arguably left behind the SoA (state-of-the-art) by ca. half dozen generations (14, 18, 22, ..., 40+ nm), this may indeed affect their sensors and vertical integration. Yet Nikon has shown that these are not show-stoppers, albeit itself not a model in innovation vs. Sony et al.

Negative marketing doesn't sell product.

Where's the Canon who's pioneered the production of CMOS sensors, first sub-$1000 dSLR, not to mention the long line of AF and DIGIC achievements, etc....?

While in the multi-B$ evolutionary process you may no longer keep up with Samsung, Intel et al. - moving to 14nm CMOS and below, one can not find proper words for your marketing spin... Embarrassingly pathetic?

We thought that eventually you'll recover, move over to Sony sensors, innovate everything else - and surprise us with new series of dSLRs and ILCs. Truly innovative.

Since yrs. you're spiralling down faster and faster, while the awed spectators on the ground expect a miracle: Your amazing feat of acrobacy every moment now... with Canon soaring again above everybody else...

Kodak has invented the digital photography decades ahead of the rest, and you. It died, albeit it took 20+ yrs of painfully obvious lack of market understanding.

Like Kodak and other greats before, now it's your denial phase. Not nice.

D1N0: Great Job Canon. Now stick in a Sony sensor.

Joseph: I'm not holding any breath, knowing how many years, even decades, it takes to change the incumbents... Meanwhile i'm shooting a variety of cameras, and much appreciate an OVF whenever i'm lucky enough to find one.

I don't root for any particular sensor size/format. But i avoid whenever possible the joint-tearing neck-breaking bodies, when lighter/smaller tools can still do the job.

Though i'm not using them yet, Sony's Q-series shows how small an APS-C camera can be. With that i could hike, run, climb, ski, canoe & portage... as an example, vs. the studio- and car-oriented pro-dSLR's

Even with the best Sony sensor (if ever), largest buffer and fastest AF, this design will remain confined to its niche. May sell in the 10s of K units, perhaps cross into 100K... and hopefully signals the end of an awkward transition era from SLRs to (true) digital cameras, as started by Kodak in the mid'70s, and finishing not soon enough with Canikon's endless variations of multi-pound dSLRs.

Note: I still shoot sometimes mechanical Nikons, and process my own silver halide... besides plethora of digital Canons, NEX and NX bodies taking the same lenses :-)

The 7Dmk2 marks the apotheosis of CFO-driven corporate design that makes even Nikon seem like a bold innovator in the dSLR space.
