I think we've finally came to the place where consumer-grade digital cameras will quickly begin to fade out. The images and video coming from the 4S are mind-blowing -- I'm still dumbfounded such a small lens array can produce such clear photos. (Check Vimeo's iPhone video channel.) The only thing my 4S lacks that my point-and-shoot has is an optical zoom. Beyond that, the phone's ecosystem of photo apps plus the abi…

As for still shooting, you may want to take an inventory of the places that people use their point-and-shoots. In my surveying, they're almost only used in places where macro, low-light, flash, speed (image stabilization) and zoom performance are very important: birthdays, landmarks, weddings, kids events, zoos. And those are features where the known solutions just do not fit into the physical constraints of smartpho…

Don't forget drunken photos. The iPhone is relatively unforgiving when it comes to mashing what I think is the button - with my camera, I know where to put my finger and press, and I get tactile feedback.

Either that or the consumer-grade digital cameras will start to evolve in new directions. I think we're already seeing the beginnings of this with Lytro's light-field camera, for example. I wouldn't be surprised if we start seeing light-field cameras from the major manufacturers (Canon, Nikon, et al) in a few years time. And given the physical constraints of the microlens array, it'll before you get one of those in a mobile phone!

One thing smartphone cameras still don't do for me is minimize the time between wanting to take a shot and taking a shot. This is one area I think consumer cameras could also be improved. Ideally I'd like one button for pictures, one for video -- mash it down, the camera powers on and figures out what to do as fast as possible.

Compact cameras are still terrible in that regard; you can only get that 'off to photo taken in 0.3 seconds' with SLRs today. It's thus not really a valid argument for compact digital cameras still having relevance.

Imagine that your customer is drunk.

Digital cameras win hands down. Slam the power button, slam the photo button, and you have at least a blurry blackmail-worthy shot of your friend dancing with a hobo.

With a mobile phone, by the time I get the app up and running, the hobo is gone and my friend is left with nothing but hobo sweat.

As of iOS 5, you can now use the volume-up button as a way to take pictures, so you get that tactile feedback.

Not true, as per the scientific method you only want to test typically along one dimension (in this case sensor quality). If the cameras are subject a random motion which causes blur greater than the blur caused by low-light conditions then the results are meaningless as the random motion is independent of the variable being tested.

I disagree because you want to test photographs from a human holding it, not a tripod holding it. Perhaps you could take dozens of shots with each phone and compare.

suivix nailed it. Photography is not one dimensional. A great photograph with a camera phone must be handheld. Suivix's point about taking a great number of photos then comparing the results with a huge sample then making a quantitative assessment would be the only correct way to test it.

This post wasn't about the quality of the sensor it was about the quality of the photograph.

I agree. I am the furthest thing from a pro photographer and always take blurry shots.

But with the 4S they're all focused and crystal clear.

The iPhone 4S has made great strides in this regard.

On my Galaxy II, whenever I want to have the camera functionality ready, I open the camera app and press the power button. The screen turns off, and I simply need to wake the phone back on to be immediately ready to take a blackmail picture.

This is even quicker with the "NoLock" app that disables the lock screen.

My Finger DNA has already memorized "Double Click + Camera Icon" from the lock screen, and then hit the shutter release/+ button on the iPhone like mad.

Even on the relatively poor shutter speed iPhone 4, I'm usually taking pictures within 2-3 seconds. Supposedly the 4S has significantly reduced the shutter-lag to first picture - looking forward to seeing the truth of that.

Increasing the number of photographs would definitely make this more significant (as increasing the sample size in any experiment does).

My point is that regardless of if a 4S shot better photos, the photographer could hiccup and get a blurrier photo than they might have taken last with a 3GS. In a less extreme circumstance, they could have just exhaled instead of hiccuping, in which case no one would have noticed and the error could be incorrectly attributed to the camera.

A great photograph with a camera phone requires a certain set of parameters that can almost entirely be individually measured outside of human interaction (and randomness). If you want good handheld performance, you need a fast exposure time, which can be measured from the EXIF data of each photo. If you want high dynamic range, measure the ratio of pure white and black pixels to the rest of the image (white and black is basically over/underexposed). The only thing that would be effected by motion that I can't think of how else to measure beyond being handheld is time to good focus (outside of crazy contraptions that result in more repeatable motion, like sticking your phone in a centrifuge), but there probably exists a way to do so while avoiding the inherent non-repeatability of humans behavior.
