Eric00: They are 'a coming. We can analyze this new offering by Sony all day, but what is unmistakable is that smartphones will continue their relentless evolution and that the vast majority of world consumers will continue to make them their primary photo capture devices. Saw a recent statistic identifying over 90% of world photos taken were taken with a smartphone. That certainly means something, and Sony, Apple, Samsung, and the slew of Chinese companies entering the market know this and will throw yearly resources to the venture in massive quantities. Don't see anything from traditional camera companies in the everyday consumer horizon to even attempt to stop them.

Of course about 100 times as many photos are taken compared to the pre-cellphone era. Photography has gone from a niche hobby to something almost everyone does.

7seven7: The glossy screen is unacceptable !
A fixed glossy screen at home is easy to angle into shade, to shield from light, and you can even edit with a black balaclava ! ;) But on a laptop that always has its screen more or less directed towards the ceiling where the lights are, not to mention outdoor use, a matte screen is mandatory !

Agree. I made the mistake of getting a laptop with a shiny screen. Completely useless outside, including in a car or train.

3Percent: "You don't get something for nothing..." no matter how good the promise. Something to think about.

Noise reduction in this case is actually just a better demosaicing algorithm. It is a one step process, not demosaicing followed by noise reduction.

n_c_v: Is there any image quality improvement from stacked CMOS comparing it to a BSI sensor?

Generally no. The advantage of a stacked sensor is faster readout times. This is particularly advantageous in reducing the rolling shutter effect in video.

On article Leica's M11 risks rendering the rangefinder obsolete (351 comments in total)
In reply to:

Lessiter: If someone buys a rangefinder camera they presumably want the rangefinder. (lets ignore collectors for a moment) If you want a rangefinder no amount of additional features and aides will make the rangefinder obsolete. The additional aides may help those who just want to use Leica glass however.

In photography and all other arts the process and tools affects the outcome. Different cameras make you take different photos. All photographers should know this. Choosing your tool is part of the creative process.

The assertion that the M11 risks rendering the rangefinder obsolete is based on a non artistic "getting the shot" view of photography. In reality that's a niche confined to press, wildlife and event.

"The assertion that the M11 risks rendering the rangefinder obsolete is based on a non artistic 'getting the shot' view of photography. In reality that's a niche confined to press, wildlife and event."

I think it is a niche covering about 95% of the market. Events include just about any social activity. There is also children's sport and street photography. People for whom photography is primarily art are a very small percentage of the market.

CJAM: How long before they drop the "film" part of their name? We must be approaching the point where some youngsters won't have any idea what a film is (in connection with a stills camera)

@GregFranklin
"There are many young enthusiasts that understand, and appreciate analog format."

Yeah, some people like steam trains, but they are an obsolete technology for any purpose other than nostalgia.

Nielk Mike: What did the CEO say? The photography business they continue as a service to society. Why do I have the feeling that such a statement is unlikely to translate into future investments and developments? Very much like Fuji cameras. But I am rather pessimistic.

"The photography business they continue as a service to society. Why do I have the feeling that such a statement is unlikely to translate into future investments and developments?"

Fuji has been saying that for years. Fuji has a very long history in the photography business and a continued presence is a matter of prestige, public relations and branding.

thx1138: X-H2 with 40MP stacked BSI sensor, 8K UHD.

Fuji announced in September that it will be a stacked sensor, so that part is definite.

GiovanniB: Perhaps they'll release a Bayer version? Those X-Trans RAW files just don't fit my current workflow well - the results in LR are simply terrible for some subjects. But then it's a minor issue for me because Fujifilm X is just my secondary, reacreational system anyway and I also have C1 which processes these RAWs very well.

@FTOG
"If Fuji gave up X Trans on a flagship model of all things, they'd have to find a compelling rationale to defend the move."

How about Bayer requires less processing and that the 40 megapixel sensor / 8k 60 fps video is so demanding in processing terms that Bayer is the better choice.

Fuji uses Bayer for its medium format cameras. If the new camera has a 40 megapixel sensor, then Bayer could make sense.

BklynBill: Leica should have been included, they will definitely be a survivor( Though I'm not sure if that is true of their mirrorless models- but I bet against them.).

"Fuji owners are delusional if they think that the company's business model or appeal is the same as Leica's."

Very true. Leica appeals to pretentious people who feel better if they overpay for a mediocre product. Fuji users, by contrast, want an enjoyable photographic experience at an affordable price.

On article Gear of the Year 2021: Barney's choice - Nikon Z9 (531 comments in total)
In reply to:

Richard Murdey: I'd love to know the story behind the low price. It Nikon selling at or below cost to garner goodwill and kickstart Z-adoption among pro photographers? Or does the Z9 really cost substantially less to manufacture than the D6? And if so, what's up with Canon then?

I would be confident that it is priced well above production cost. The real issue is how quickly they are trying to recover R&D cost.

Jacques Cornell: Regarding the Studio Test images, folks, it's worth downloading the RAWs and processing them yourself in your app of choice, as the results can be wildly different from what you see on DPR's web page. The a7III's high-ISO noise "advantage" over the a7RIII (I have both cameras), which seems so clear on the web page, essentially disappears when I process both files with DxO PhotoLab 5 Elite and apply DeepPRIME noise reduction.

As I said, demosaicing always involves guessing at detail, so this is not new with DeepPRIME, which is just better at it. You need a Foveon sensor to avoid guessing.
I understand that the less noise in the raw file the better, but DeepPRIME apparently makes it a less significant problem.

@Kerensky97 "Noise reduction doesn't create detail where none existed, it only smooths out noise."

DeepPRIME uses AI algorithms to do demosaicing and denoising in a single process (you can't use it on JPEGs). This may involve guessing at detail in which case detail may be "created". In fact, all demosaicing involves guessing at detail. In any event, it seems to be agreed that it works extremely well.

Puppy2007: How much difference would have been seen in a real photos? This is typical synthetic test. IMHO all camera at similar price point is great nowadays. Sometimes I feel people have forgotten it is about taking pictures at the first place, not pixel peeping nor testing corner cases. Post processing will make it even less important on the end.

By this reasoning, there shouldn't be any camera reviews. "Heh, they are all great. Just go out and take pictures."

John Carson: The specs table says that the Canon syncs with lens stabilization, but the Sony doesn't. My understanding is that the Sony has synced lens and in-body stabilization in the past. Has this really changed? If so, why?

Thanks for the clarification Richard.

To answer my question, apparently the Canon's two stabilization systems talk to each other, whereas other cameras just decide which axes each stabilization system will be responsible for.

Anyone with a smartphone can add a Japanese time clock. It took me about 15 seconds.

SilverBelle: I don't know if $1499 for camera body only should count as "best camera under $1500." Also..... cameras are getting ridiculous. I'm going to say for 90% of the hobby shooter and semi-pro market there is already a camera under $1000 that will do more for you than you will ever need. People are counting on technology to make up for their laziness and poor shooting skills.

"People are counting on technology to make up for their laziness and poor shooting skills."

Yes, that is one of the main uses of technology. What is your point?
