Nereo: Um... I'm beginning to think we need a new standard other than "ISO" to measure light sensitivity.

ISO came from the sensitivity of coated glass collodian plates (ISO ~1 !) Then came the films, and it was still easy to keep track that ISO 100 was 4x as sensitive as ISO 25. But now we've got cameras with ISO 102,400 and now 4 million?! Quick: how many stops between 1600 and 102,400?

Since camera sensitivities now exceed two orders of magnitude, why not have a sensitivity measurement that matches? e.g. ISO 100 = 1, 200 = 2, 400 = 3, 1600 = 4... each double the previous level in sensitivity.
This new camera exceeds "16" on our sensitivity scale!

I appreciate the irony in your rebuttal Bob. The temperature bit particularly.

Seeing as over the last 50 years the use of the celsius scale, with it's more accessible (0 - freezing water 100 - boiling water) range having replaced the higher resolution fahrenheit scale. Not to mention that neither popular scale is close to useful for real measurement, compared to the much more logically laid out Kelvin and Rankine scales.

Similar for bolt torque. Measuring bolt torque is a sloppy and imprecise indirect *estimate* of the clamp load on the fastener, which is really the important value. But measuring torque is the popular measurement because it is easier to measure, and more accessible for lay-people.

At least we can agree that improving accessibility by toning down the geeky-ness of a measurement is a good thing for growing acceptance in the general population. Even if you don't realize it.

Eleson: What is the intended usage and audience for this camera?

Very dedicated Peeping Toms.

I suggested something similar back a few years as a method of making photography more accessible to people that don't want to be tech-nerds.

I was ridiculed by the purists that I "didn't get it." That it was important to keep the conventions as they are because change is bad and only people that devote the time to learning nerd-stuff deserve to understand how to use a camera, etc. etc

Why the 3.5mm mic jack? Seems rather out of place on a $30K video camera.

PowerG9atBlackForest: Guess what? We've seen it all already! Not the one million minutes in one piece - but bit by bit: Twiggy and Marilyn, and wasn't that terrible at Lakehurst and Pearl Harbour. Oh, those sweet clips of nostalgia every now and then!

My son is 8. He's never seen it. If/when the time is right to discuss it, I can quickly find it on Youtube. That's a great resource to have.

Too bad people just get snarky as they get older...

Meh. Don't like their contract, don't show up at their venue to take pictures... Pretty simple really.

joelakeland: Amazon Prime is awesome for shipping and if you live in a state where sales tax isn't collected, still better. Amazon Prime for TV streaming and Music streaming...not so much. In fact, they ought to shut the TV streaming down. I'm in the market today for a another camera so next week is too late for me.

Meh, I was about to say that prime shipping by itself isn't all that great, but when you add on streaming video and music, it becomes a heck of a deal. I personally would not keep a prime account if they shut the "TV streaming" down.

To each their own.

I just wish there was more than one option for buying this camera from Amazon. I don't know, maybe offer it as part of a bundle or two...

Still not good enough to take pictures with my dog's eye in focus and his nose out of focus.

Suntan: Very impressive tech. Too bad Sony can't cram a usable aperture dial and a shutter speed dial on that little RX100.

Jeez pal, find someone else to critique, the internet is big enough. I simply commented on what I would like to see. I'm not interested in having a grand, metaphysical discourse on the universal harmony that is Sony's business plan...

I already have the LX100, because I believe it has a vastly better control layout than the RX100. That doesn't change the fact that I think the RX100 would be a better camera as suggested above.

They can eliminate the amateur "mode" dial and put the shutter speed dial in its place. Then put the aperture dial around the lens. Basically, they should copy the LX100 layout for shutter and aperture control.

moimoi: The Blue Room photo is both disturbing and outstanding. Thanks dpeview for sharing this set of superb photographs. It makes me want to work harder and better...

Just move on, good advice... For someone that dredges up a 2 week old thread.

mosc: Survival comes before the rule of law. I wish more wealthy citizens would fully understand this. If you don't provide for the basic survival (physical and mental) and well being of an individual, they will in turn have no regard for your legislation. Prison is not a deterrent when you have no food to eat. It's an ancient concept. Stealing a loaf of bread to avoid starvation is a moral act.

You cannot legislate (ban underage sex trafficing) your way out of this problem because the issue is not one where the rule of law applies. It's a socioeconomic problem.

Didn't expect to see this on DPR but it's interesting.

This isn't about either of those things. Human trafficking in America doesn't fall along social or economic lines. Usually it starts by young individuals making poor choices (think - going to meet this guy I've fallen in love with over the internet for a weekend in Vegas) and then promptly getting in way over their head to the point that they are too embarrassed/psychologically battered to call their parents/law enforcement for help.

You quip about Americans being too dim to appreciate nuances more than good and bad, but in almost 100% of the cases trafficking occurs because of very bad people doing some very black and white things (with absolutely no shades of gray) to other people.

For anyone that has the misplaced notion that this has to do with our government not giving people free food, or Americans not being able to see "shades of gray," I highly recommend watching the documentary "Tricked" which is available streaming on Netflix.

What I have seen/read from watching similar documentaries on the subject, is not so much an issue of "survival because the government didn't provide me with food." So much as it is "survival after an individual/group of individuals stole me and forced me (physically/psychologically) into this situation."

Simply put, kids aren't voluntarily getting involved in the human trafficking scene because they are hungry.

Suntan: I don't really have a dog in this fight, but I must say, looking at that tulip image full-size, the quality is really rather poor.

Downsampled the image looks nice, but then, who buys a 50mp camera just to downsample the images?

Again, I have read DP long enough to appreciate that they would not have posted the image, in a discussion about the camera's dynamic range capabilities, if they did not feel it was a close representation of what people should expect.

Basically you're suggesting that people should ignore the article...

hotdog321: Love the "Tulip Sunrise" shot--just a gorgeous image!

But when I downloaded the high rez jpeg, I was pretty shocked at the noisy shadows. The 5D S/R doesn't appear to be nearly as good as I expected.

Not a troll--I've been shooting Canon professionally for 35 years. I'm honestly looking forward to the hypothetical 5D IV or 1DXX, but they better do a better job on these cameras than they did on the 5D S/R.

Agreed. The image looks nice at small scale, but really suffers when viewed high resolution.

Who needs a 50mp camera to make pleasant website photos?

@How
I am making the assumption that the DPR folk processed the image with integrity.
Be pedantic if you want, but that isn't an image that I would publish in high resolution.
