In reply to:

englishfil: Real world situation: company needs a portable 60 Mpixel+ camera for a new application. Must be rugged, compact with a large sensor (i.e. no phone sensors yet, although they are showing promise). With help of DXOMark narrowed choice to guess who? Yes, the price is eye watering, but where is the competition? I am sure Leica would not survive if it just did "ME TOO". Add side benefit once we looked into it more = we could swap out the M11 for an M-A or even an old M6 TTL and avoid electronic dependence. Still, just about, recover 60 Mpixels with the right film and a professional scan. Never thought I would say it, but I can see a reason for Leica.

Short answer: for the Sony it is form factor - the camera is being attached to equipment in the field. Also explains why pixel shifting is not an option - needs to record output at an instant. Not trying to justify Leica's existence just pointing out that you can arrive at Leica being a solution without being a dentist.

Einride: RED is nothing but a patent troll. They’ve done this before and will do again. I really hope they lose.

RED actually make something. Something that uses their patent. They are not patent trolls. The questions as to whether their patent is too general (and therefore can be crushed), or if intoPix's licence actually infringes it - well stand by to find out. RED waiting until someone meaty actually uses TicoRAW leaves a bad taste, but then it may just be a line in the sand. Companies that rely solely on legal defence of their IP generally do not do well in the long term - RED shareholders take note (IANAL).

BrentSchumer: Everyone in these comments: "But the concentration is so small? Why can't the EPA carve out an exception for this one product I really like?"

The EPA: "Yeah, we need to regulate millions of products and inspect/test to ensure that dangerous substances aren't being misrepresented. Blanket ban it is."

Of course the same people who decry red tape and regulatory burdens are the first to shout against a simple rule that avoids costly oversight.

I searched out what the EPA regs actually say. Not sure that Fuji's statement is more excuse than valid reason. But challenging government on the science behind their edicts is no bad thing. I have no interest in using this film, and the EPA does not regulate my country, but I do have an interest in pointing out bad laws made without proper impact assessment.

Good, but I predict in two months time there will be a Chinese clone on eBay (apparently other auction sites exist, but I cannot think of any) for $8 including shipping.

englishfil: I am generally in support of measures to protect the environment. I also in favour of proper scientific analysis being used in support of the creation of those measures. I have a few questions:
1) How many rolls of Fujichrome Velvia 100 was Fuji selling in the USA per annum?
2) Is there any mechanism/location on US soil (sic) where the sales of this film at these volumes would likely cause significant (even measurable) concentrations of PIP?
3) What will be the cumulative environmental impact (CO2 production etc.) of dedicated US Velvia users buying up existing US stocks and then keeping them in freezers for several decades?
4) What is the risk to US Velvia users of regulations further tightening so that in the future films must be exported for processing?

A follow-up: I have found a partial answer on here to 2. Concentrations could occur in places of manufacture and distribution, presumably including import hubs. Good answer. Someone states that there are no safe levels of PIP - as a scientist I cannot accept that as true - concentration is everything: a summary of EPA regulations (Effective March 8th, 2021) says prohibition unless "less than or equal to 1%. " I am not advocating being around toxins - just a recognition that everyone is, everyday, and we are not all dead (yet).
The other questions go unanswered. Note I am an not in the US and the last chrome film I used was Kodachrome - long since gone. I have no vested interest in keeping this film in use; I do question both Fuji's real reason and the true environmental impact assessment. If people cannot address questions like these as adults maybe don't comment?

On article Hands-on with the the Canon PowerShot Zoom (124 comments in total)

"Menus are navigated and options selected using the buttons alone." Hmm, twas ever thus with Canon - one of the reasons I switched from Canon to Nikon Pro SLRs and have not gone back.
"The still image quality of the PowerShot Zoom is no match for a more conventional camera, or even for a smartphone, " So can I buy a '400 mm' lens that can be clipped on my iPhone? Actually yes, and it will cost less than $299.
Sad really, because I like the idea of a stabilised monocular that can record what you are watching. So make a better device for $299 or sell this at half the price? Hey Canon, let me know when you decide.

milkod2001: Wonder what shutter speeds and ISO must be used when minimum f stop 11.

Hmm, I don't know how about starting with the 'sunny 16' rule: average mid-tone subject, sunlit, cloudless sky. f/16 and shutter speed is reciprocal of ISO. Its f/11so half shutter speed. Under these conditions to use handheld set ISO 400. Cloudy ISO 800. Deep Overcast ISO 1600 usw. If you have current generation DSLR probably not worried about noise until ISO 6400 at worst. If you have fast moving subject and you are working under floodlights sorry you will still need a big white lens. For everything else this a nice affordable alternative. For those mentioning diffraction - only an issue if your 60MP camera is converted to Mono capture; F/11 is just on the limit for Bayer colour capture.

cshyde: You can buy a similarly equipped HP Spectre X360 for the same price with Windows 10 Pro. What you get is a lot less annoyance, a touch screen and longer battery life, more USB ports and you don't have to put up with iOS. Apple is now like Tesla, they look good on paper but owning one is not satisfying.

iOS? You mean MacOS, i.e. UNIX, a grown up operating system significantly more efficient than Windows. However, i take your point wrt. touch screen and USB ports. Apple charges a premium that takes some justification or a corporate or educational discount.

In reply to:

rationalist: „ Sony investigating light field technology“.
Calling this light field technology is a big stretch. The only light field cameras so far have been presented by Lytro. It requires at least not only to read the intensity but the direction of all the light rays hitting one pixel. That‘s why Lytro’s cameras had such a low resolution.

Anything that can record directionality could arguably be called light field. However, I agree that 5 lenses seems too few to allow significant recovery of direction. I would have "simultaneous stacking" would be better description of what could be achieved. There will also be a parallax issue with close up objects. How far computation, A.I., etc. can overcome the issues remains to be seen. Hats off to Sony for trying to move things forward though.

I have been a big critic of Apple since the new generation of MBPs started to lose their intended market. However, I will admit this is a step in the right direction. Sorting the keyboard, having a real Esc key and more battery life were things that needed fixing - and Apple have done that. I would still like Magsafe and a useful array of ports, but concede there are now low cost third party solutions to fix that. So if Apple would only charge more realistic prices for the higher RAM specs I might even consider buying one.

The more the boot is put in to Apple's marketing the more orifices it will start bleeding from. Hopefully the pain will finally filter through to its rather slow brain and it will start making products worth buying again; or just die .. I have to say I am largely past caring.

Yep, sounds like course work from 35 years ago. I don't remember it being called "computational photography" back then and it was ASCII not emojis, but hey whatever floats your boat. We could not do it in anywhere near real-time either, so progress.

Have none of you heard of virtual machines?
Software doesn't die it just goes virtual.
If your Aperture is stable under whatever version of MacOS you are running then just build a VM with that OS. Then shift your licensed Aperture to that VM and reconnect all your libraries (caveat: you may need to read the manual/help files!!). Now if you want to use Aperture just open up a VM a window, just like I do for the last standalone Adobe Creative Suite and an older version of PS (separate VMs). Plenty of info on interweb for creating free VMs or buy a commercial product such as Parallels. VMs really are the way to stop idiosyncratic marketing decisions screwing over your life.
Unfortunately there is currently no way of creating a physical 'virtual machine' that can replace Apple hardware; Hackintosh comes close, but has major limitations. Let us hope Apple's recent retrograde hardware growth figures will force some reality into their hardware designs.

Ad B: I really hope the 20 and 24 mm f1.8 wil be smaller as the 35 and 50 mm.
Small cameras needs small lenses.
More wishes...? Sure.
More at the long end.
A longer walk around lens, 24-120 or 24-longer..., and a not to heavy telezoom 200-500/600.
That's all...

but, but PHYSICS? You cannot have full size, small sensel sensors and fast apertures without large glass. You could take the Blad X1D approach and go slower to keep the size down, but it that what pros want? You could skimp on lens body and lens materials and strip some weight at a potential loss of quality and longevity - again is that what pros want? At the end of the day ditching reflex offers some weight saving, but you cannot ditch all the size and weight and retain the all the features pros are used to.
[Where I use the term pro I mean people earning from photography although the same issues apply to serious amateurs/enthusiasts. No offence if your hobby does not pay for itself, but you still strive for the very best quality]

Franz Weber: Ten years ago, I saw an interview with Steve Jobs. He stated that if someone wants to watch porn on his smartphones, he should better buy an Android phone.

I don’t know why he made that recommendation, but the next day I bought my first Samsung.

Steve is dead ...and guess what, you can watch porn on iPhones. So you might not get an app that does it - apart from several web browsers. Shame the US has a problem with grown ups, but hey the internet routes round .. it was designed to.

They got bought by people who did not understand what they were buying. They have faced a real problem with kidi porn and have probably been told that there is no perfect solution. Rather than spend hard money trying to sort the wheat from the chaff the path of least resistance is ban all adult content. That way it is easier to spot offenders. It is a shame for all those adults who used Tumblr to premote their legal kinks,but it is Tumblr's ball (sic) and if they want to take it home they can. I predict a somewhat radical shrinkage in utilisation - remember Myspace anyone?

Keith Meinhold: Seems to me KC is trying to sell itself as a tourist hotspot. Here in Miami, I bet we get 1000X the photographers and take it in stride - snowflake.

Cue "when snowflakes get together they form galciers" comment. So you upset someone and they complain and you think they should not complain so you label them a 'snowflake'. Maybe next time they will keep quiet - and stab you in the eye instead.
