Let me say first, you are right in that the iPhone 8/8+/X, and probably the next five models that follow, are no match for a modern DSLR with good glass operated by a skilled photographer, especially when shooting conditions are challenging and when the resulting shots are blown up to 20x30 and compared side-by-side. The laws of physics simply prevent a sensor and lens on a smartphone from duplicating what the large sensor and quality glass on a DSLR can do. At least for now...
This exactly. The smaller sensor means the lens will have to much more resolving capability to give the iPhone the same image quality as the DSLR. The optical resolution of the lens needs to be much better for a smaller sensor, all other factors being equal. The same lens will give a more blurry picture on a smaller sensor. Add to that the fact that the lenses aren't equal and you exacerbate the problem.
For many people, 4x6 is good enough. Even at 8x10, an iPhone shot can look pretty darn good.
Agreed, but then how many people on this thread are saying the iPhone is just as good as a DSLR full stop.
When you you say for many people; that is the same segment of the population that never cared; they're the kind of person who would have owned a cheap 35mm point and shoot or even a 110 camera back in the day. They want quick and dirty 'memories' and not high quality photos. And there's nothing wrong with that. Most people didn't want an SLR in 1980 and most people don't want a DSLR in 2017.
What is new to this decade is the attitude of "my way is the only way". So if thy don't see the benefits of a DSLR for them, then those benefits don't exist. People today seem to have inferiority complexes and need to convince themselves and others that the way they do things is the only possible way and anyone with a different idea is wrong and needs to be put down.
When you read someone posting that "the new iPhones seem to be as good as a DSLR", don't take it so literally. What they mean is, at the iPhone display size or when printed at 4x6, it can be hard now to tell a DSLR and an iPhone image apart.
And this is precisely the point. I'm saying the DSLR gives a better quality image and you're saying that if you look at it on a tiny, low resolution display you'e got the same image quality.
It would just be just as meaningful to say 8k video is no better than old fashioned NTSC at 486 lines. As long as you're viewing it on a 10 inch standard def screen from 10 feet away. While that is perfectly true, nobody is going to say NTSC is on par with 8k video. Just as nobody in their right mind would say an iPhone is on par with an SLR because when you view in tiny low res you can't tell the difference.
Think you can spot the difference between an Apple QuickTake picture and a Nikon D5 picture when you're viewing them on an Apple ][? I guess that 1994 Apple point and shoot can compete with the best DSLRs pretty well after all. Makes you wonder why the QuickTake flopped so badly, it was a heck of a lot cheaper back then than the D5 is today.
And if you want to limit yourself to iPhone displays or 4x6 prints, the difference between an iPhone 5 and iPhone X is meaningless. It's like arguing which of two snails is faster when there's a Ferrari in the race.
Also, I can run faster than any Ferrari sports car every built can drive. Up a flight of 12" tall stairs.
Blown up or zoomed in, I can certainly tell the difference. But at 4x6 in outdoor conditions, it's often damn closee
And at 4x6 you can tell which generation of iPhone shot the picture so easily? Then why do people talk about each new iPhone camera like it's some major miracle. It's a 2-edged sword. If the viewing condition is so poor you can barely tell an iPhone from a DSLR, how different do two iPhones look at 4x6? Or the iPhone X vs any Android flagship?. They're all basically the same thing, and yet people spend hours pretending it's a major distinguishing feature.
Especially from the standpoint of color, contrast, and dynamic range.
Contrast is more a function of cooking the raw file, raws are very flat before ACR or some equivalent gives you a starting preview. You can get good contrast from any camera, its just up to you or the software to process it correctly. Dynamic range on the best DSLRs has only recently caught up to film and the iPhones are still years behind on that.
