| This is on a long list of why camera companies are dying. There is a long list of issues like this which have prevented ecosystems from forming around cameras, in the way they have around Android or iOS. It's like the proprietary phones predating the iPhone. The irony is that phones are gradually passing dedicated cameras in increasing numbers of respects as cameras are now in a death spiral. Low volumes means less R&D. Less R&D and no ecosystem means low volumes. It also all translates into high prices. The time to do this was about a decade ago. Apps, open formats, open USB protocols, open wifi / bluetooth protocols, and semi-open firmware (with a few proprietary blobs for color processing, likely) would have led things down a very different trajectory. Sony is still selling cameras from 2018: https://electronics.sony.com/imaging/interchangeable-lens-ca... The price new fell by just 10% over the 7 years ($2000 -> $1800). And in a lot of conditions, my Android phone takes better photos, by virtue of more advanced technology. I have tens of thousands of dollars of camera equipment -- mostly more than a decade old -- and there just haven't been advancements warranting an upgrade. A modern camera will be maybe 30% better than a 2012-era one in terms of image quality, and otherwise, will have slightly more megapixels, somewhat better autofocus, and obviously be much smaller by the loss of a mirror. Video improved too. The quote of the day is: "I wish it weren’t like this, but ultimately, it’s mostly fine. At least, for now. As long as the camera brands continue to work closely with companies like Adobe, we can likely trudge along just fine with this status quo." No. We can't. The market has imploded. The roof is literally falling in and everyone says things are "fine." Does any know how much volume there would be if cameras could be used in manufacturing processes for machine vision, on robots / drones, in self-driving cars, on building for security, as webcams for video conferencing, for remote education, and everywhere else imaging is exploding? No. No one does, because they were never given the chance. |

A modern camera will be maybe 30% better than a 2012-era one in terms of image quality, and otherwise, will have slightly more megapixels, somewhat better autofocus, and obviously be much smaller by the loss of a mirror. Video improved too. I thought the same thing, and then I went and rented a Nikon Z8 to try out over a weekend and I was blown away by the "somewhat better autofocus". As someone who used to travel with a Pelican case full of camera gear, to just carrying an iPhone, I'm back to packing camera gear because I'm able to do things like capture tack-sharp birds in flight like I'm taking snapshots from the hip thanks to the massive increase in compute power and autofocus algorithms. "Subject Eye Detection AF" is a game-changer, and while phones do it, they don't have enough optical performance in their tiny sensors/lenses to do it at the necessary precision and speed to resolve things on fast-moving subjects. In terms of IQ, weight, and all that, it's definitely not a huge difference. I would say it's better, but not so much that I particularly cared coming from a 12-year old DSLR. But the new AF absolutely shocked me with how good it is. It completely changed my outlook. I say this, not to take away from your overall point, however, which is that a phone is good enough for almost everyone about 90% of the time. It's good enough that even though I upgraded my gear, I only bought one body when I traded in two, because my phone can handle short-focal length / landscape just fine, I don't need my Z8 for that. But a phone doesn't get anywhere close to what I can do with a 300mm or longer focal length lens on the Z8 with fast moving subjects. |

| ▲ | Koffiepoeder 11 days ago | parent [-] | | I use my Canon EOS 90D fairly often, but there is one exception for me. For low-light conditions my phone often exceeds the performance of my camera. Especially for high movement & dynamic scenes, I would definitely recommend having a high end phone nearby :) | | |
| ▲ | tristor 11 days ago | parent | next [-] | | The sensor in the 90D isn't capable of the high ISO performance of some newer sensors. For low-light conditions the things that matter more than anything is: 1. pixel pitch 2. sensor ISO performance 3. native denoising For sure a new high end phone will do better than a mid-range camera that's older, but on the high-end it's the other way around. My Z8 has significantly better low-light performance than my iPhone 16 Pro, however the upside from the iPhone is that I don't need to do additional denoising in post-processing (I usually use DXO) where it's required on anything taken above around ISO 12800 on a digital body. The Z8 is usable to print (e.g. noise is almost completely removable if you aren't cropping) up to ISO 25600 (which is the maximum ISO of a 90D), and is usable for moment capture (e.g. not trying to win any awards) nearly to its maximum ISO (102400). Many newer camera sensors, including the Z8's sensor, are "dual gain", meaning I can shoot basically noiseless at ISO 500 w/ almost 13 stops EV of dynamic range preserved, which is simply not possible on any phone camera or on most older bodies. If you're shooting in low-light often enough, there are specific sensors and cameras which are far better than others, even if the other cameras would be better than in other situations. Generally speaking though, larger sensors are better than smaller sensors in low-light at the same pixel pitch. In the Canon world, an R6 II is comparable to the Z8 in low-light performance, although I think the Z8 just barely edges it out. So don't take anything I'm saying here as being brand-specific. Modern full-frame mirrorless cameras are almost all better at low-light performance than any preceding full sized (DSLR style) camera, mirrorless or not, because the sensors have gotten better but maybe even more importantly the native denoising has gotten better. | |
| ▲ | frognumber 11 days ago | parent | prev | next [-] | | <-- This People are leaving off which lens. In my experience, for low-light: Large sensor + kit (zoom) lens < Pixel Pro < Large sensor + f/1.4 prime It's not apples-to-apples, since my phone has no optical zoom in the lens (although it somewhat makes up for it by having wide/normal/tele fixed lenses). But shooting with the main lens, it definitely beats a large sensor for low-light with a kit lens. I think the key difference is intelligent multiframe denoising algorithms on the phone. It, in effect, shoots a video and combines. | | |
| ▲ | tristor 11 days ago | parent [-] | | That's very true, lenses on a camera work very similarly to a telescope. A larger objective (opening at the end of the lens) combined with a large aperture (lower f number) means that a lens is able to gather a lot more light at a given focal length. Certainly some of my commentary is related to the fact that my primary lenses are f/0.95, f/1.2, and f/1.8. I only shoot "fast" primes on a camera body. That said, a /lot/ of low light performance is simply having a much larger sensor with a wider pixel pitch that is able to gather more light in the given time allotted. You cannot beat physical size in some ways for digital photography and light gathering is one of them, as it is primarily about surface area. |

| I started with a second-hand Canon 20D back in like 2004 or something, only upgraded when I got a deal on an old 7D and only recently bought a new R6II and the autofocus is NIGHT AND DAY I started buying the EF mount superfast primes because they're affordable now, but the 7D (more likely it was me) couldn't get the focus just right with such a shallow DOF The R6 just doesn't miss. Low light/high ISO image quality is also MILES better. Cameras are not in a death spiral. Artistically speaking, phones can't do what even a low end slr/mirrorless can do, its just that phones are good enough for the low-effort content 95% of people are interested in producing. Standalone cameras are inconvenient, bulky and require some level of artistic intention. >Does any know how much volume there would be if cameras could be used in manufacturing processes for machine vision, on robots / drones, in self-driving cars, on building for security, as webcams for video conferencing, for remote education, and everywhere else imaging is exploding? I don't know about the manufacturing or drone stuff, but for video conferencing and remote education, the point of the video really isn't image quality or "art" but just good enough picture to not get in the way of the real purpose of the interaction, so a whole camera kit is just added complexity/annoyance for no benefit.

Sales numbers tell a different story. > Artistically speaking, phones can't do what even a low end slr/mirrorless can do, its just that phones are good enough for the low-effort content 95% of people are interested in producing. This is not correct. A Pixel Pro has a 50 MP, f/1.7, 1/1.31" sensor. This is equivalent to f/4.6 in u43, f/6.6 in APS, and f/9.5 in FF. This is slightly slower than a kit lens on paper, but this is more than made up for by more advanced sensor technology, and especially the ability to do things like fast sensor readout, which can read out many frames and combine exposures. Side-by-side, shooting with a phone and a Panasonic u43 camera with a kit lens, I was getting perfectly good photos with the phone, and useless photos with the u43. > I don't know about the manufacturing or drone stuff, but for video conferencing and remote education, the point of the video really isn't image quality or "art" but just good enough picture to not get in the way of the real purpose of the interaction, so a whole camera kit is just added complexity/annoyance for no benefit. It depends on the context. People buy $100k Cisco remote conference rooms for a reason. I've definitely spent >$10k on equipment in remote presentation / education contexts myself, and know many other people who have done likewise. You should, at some point, figure out what popular education Youtubers, twitch streamers, etc. spend :) But there are similar contexts in scalable education, various kinds of sales, etc. One of the core issues -- in context I've worked in -- is that reliability is king. I don't want interruptions. I'm happy to have three cameras feeding into OBS and a set of fixed setups, and I've even done custom plug-ins, but something like a mirrorless adds layers of complexity which can lead to bugs: - Mirrorless -> HDMI out -> Elgato -> USB -> OBS -> Virtual camera A direct USB connection would remove a cable and an adapter. | | |
| ▲ | tristor 10 days ago | parent [-] | | > A direct USB connection would remove a cable and an adapter. Most modern mirrorless cameras can be connected to a computer via USB and used as a video source. Some are nerfed to only run for 30 minutes or some other arbitrary number consistently, but most are not. f/9.5 in Full Frame is abysmal and generally past the point where scene sharpness suffers from stopping down. Even when doing street photography or landscapes, I rarely stop down past f/8. Running something like my Nikkor 50mm f/1.2 S Z-mount lens at f/4 is sharper edge-to-edge than most other lenses at f/8, and gathers enough light to operate a pleasingly fast shutter speed for handheld work even in low-light. A phone does not compare. My wife has the latest Samsung Galaxy S, I have an iPhone 16 Pro, we both also have cameras (her a Fuji APS-C body, me the Nikon Z8 FF body), and we walk around and take photos composed correctly within each camera. We can see it, even without cropping. A camera body is much better than a phone if you care about the quality of your work, and especially if you ever intend to print. | | |
| ▲ | frognumber 4 days ago | parent [-] | | #confidentlywrong Most modern cameras can stream video to a computer through a proprietary protocol. These are implemented under Linux in gphoto2, and in other OSes, through some proprietary tool. During the great webcam shortage of covid, many companies made special, flaky Windows utilities to allow those to be used for web conferencing. Very few can natively as a USB Video Class (UVC) device. This is Canon's version: https://www.dpreview.com/news/4796043082/canon-s-new-softwar... Now, for Canon, it's a monthly subscription: https://www.usa.canon.com/cameras/eos-webcam-utility As a footnote: The general rule-of-thumb is about f/11 is where you start to notice diffraction limiting sharpness on full frame. That's a rule-of-thumb, and you're welcome to not step down below f/8, but calling f/9.5 "abysmal" is more than a little over-the-top. But no, a phone will not compare to a full frame with a $2000 f/1.2 lens. But it's quite competitive with a kit lens. | | |
| ▲ | tristor 4 days ago | parent | next [-] | | I had to board an airplane so I couldn't type a full reply earlier. Diffraction limits are different based on the sensor size, pixel pitch, and the lens optics, and diffraction affects sharpness even with a more open aperture, it's just limited in comparison to the impact of increasing depth of field as you stop down. Part of composing a scene is choosing how you want to balance DOF / sharpness, which can go in many different directions depending on what you're trying to achieve. It's simply not the case to say that diffraction doesn't affect sharpness below f/11, and diffraction is not the only impact that can affect outcomes from stopping down, when you stop down you are letting in less light over the same sensor area which affects almost every aspect of exposure, and has to be compensated for either by increasing ISO which increases noise or by reducing shutter speed which limits motion compensation when shooting handheld, all of which can affect the level of detail that is rendered sharply in a frame, either due to blurring or due to unrecoverable noise. Generally, my personal preference is to stop down enough to get a sharp frame edge to edge across the center when trying to capture wide scenes, and no more, on many lenses f/4 is enough, generally no more than f/6.3 is required. You begin making serious tradeoffs as you stop down further, especially if, like me, you shoot handheld almost always, and often manually focus (e.g. subtle movements can affect your critical focus distance). Your rule of thumb is largely irrelevant, you should be making these decisions each time you make an exposure to achieve whatever artistic effect you are going for. | |
| ▲ | tristor 4 days ago | parent | prev [-] | | Video features are manufacturer and model dependent. Nowhere in my comment did I say that they use UVC vs requiring software. My Nikon Z8 as an example can be used with OBS over USB very easily, but you must install a driver and utility. Regarding Canon, true enough, they gimp their products to be greedy. That's why https://www.magiclantern.fm/ exists. Your general rule of thumb is irrelevant. There are many optics tests done of available modern cameras, including phones. Phones get nowhere close to the photographic quality of a proper camera, but are totally fine for viewing on another small screen or small prints. My wife has had prints of photos taken with her phone hanging in galleries, but even she (who prefers a phone as an artistic style preference) would never dream of printing anything larger than a 5x8 from a phone. My photography prints on the small side tend to be 12x18, and I often print as large as 40x60. A photo from a phone is simply unusable for me. | | |
| ▲ | frognumber 3 days ago | parent [-] | | Then you have issue with reading comprehension. The whole point of the discussion was this: "The time to do this was about a decade ago. Apps, open formats, open USB protocols, open wifi / bluetooth protocols, and semi-open firmware (with a few proprietary blobs for color processing, likely) would have led things down a very different trajectory." And the rest of your posts also misquote what I said and, ironically, just as often, what you said. There are also minor technical errors: diffraction limits are basic physics. It's a simple relationship between (a) the radius of the circle of confusion (in units of angle); (2) the frequency of light (in linear units, typically nanometers); and (3) the radius of the aperture (in linear units, typically mm). There is no voodoo with "sensor size, pixel pitch, and the lens optics." Most of your post is taking statements like a basic rule-of-thumb of what you need for decent photos and exaggerating to statements like "diffraction doesn't affect sharpness." Of course it's easy to beat up a statement if you misquote it. That's called a strawman. So I think I'm done here. Give me your downvote, and I'll argue somewhere else. | | |
| ▲ | tristor 2 days ago | parent [-] | | > misquote what I said and, ironically, just as often, what you said. I haven't misquoted you, or myself, at all. Your original complaint was around the need for adapters and additional cables. I never even mentioned UVC in my reply, and you are now rejecting my clarification that you can do USB video (yes, with a driver not UVC) on pretty much any modern mirrorless camera. Diffraction limits of the optics /alone/ are not the only thing that affects sharpness as it relates to aperture, which is why I pointed out the impact of stopping down on light gathering, and light gathering is most certainly affected by sensor surface area and pixel pitch. Additionally, as I pointed out sensor size also affects the diffraction limit because sensor size influences the size of the circle of confusion. I don't think either one of us has any misunderstanding of the basic physics of light in a digital camera, you're just being obtuse. We cannot downvote each other because the system prevents it since we're replying. I wouldn't downvote you anyway, I don't consider a downvote to be a form of disagreement, nor an upvote a form of agreement. Even though I don't think you're interacting with me in good faith, you have made valuable contributions to the conversation for a 3rd party reader to learn more, and that's good enough that I upvoted your replies to me even while I disagree. |
