Love the colors, the contrast, the form. Great photo!

yellowhorse4: Periscope lens on iPhone might be worth checking out in 2022. The big question for me is how well the sensor will perform, noisewise. Having a travel camera with 320mm equivalent has been great. Had M4/3 but went to APS-C for better sensor performance, so a phone cam sensor is going the wrong way for me, but it might be just fine for bright daylight.

Having an Huawei P30 pro with 50X zoom, I can say that the long zooms simply don't work well above 5X. Much too difficult to hold stably and the IS isn't good enough. Besides, they need bright light, but in my travels, I've found that you can't see the screen well enough outdoors to hold it stable. Maybe under the shade, phone propped on something.

Vignes: For this price segment:
it looks like Sony is going into specialise path and Canon is going for one body do all path with compromise - record limit and heat management.
SONY:
1. video performance focus, A7Siii upto 4K120. limited to 12 mpx stills
2. sports stills performance focus, A9ii 20fps, can do video but limited to 8bits, 4K30-100mpbs.
3. Hi res stills performance focus, A7R iii/iv, video limited to 8 bit, 4K30-100mbps with a crop.
if you want a high stills fps >10 fps, 4K30 or 60 with 10bit and tied with E lens, you have to buy the A9 ii and the A7Siii.
with Canon, that's just R5 but with record limit and heat issues. the 1DXiii is a good option but with a high price BTW still cheaper than buying A9ii+A7Siii and we can use those EF lens. EF also works well with R system.
it's all about budget, lens collection and what works for us.
Would a Canon user with heaps of EF lens go for a Sony body with 3rd party adaptor?
Don't think a Sony user with E lens is going to jump to Canon.

Canon IBIS has already been tested by DPR as best in class. HILARIOUS!!

Yea, it has the exposure triangle. Long may it live, despite the petty minded people who insist on taking everything literally. In any automatic mode, which is like 99% of what people use, increasing the ISO lowers the exposure. The fact that exposure doesn't directly impact exposure is only important to pedants who want to show off their lack of flexibility.

No different from film. You can put in ASA 800 or ASA 64 and if you keep shutter speed and aperture the same, and the exposure in exactly the same. No, the assumption is, which some don't seem to get, that you will properly adjust the setting for the new ISO (or ASO!)

So let me practice my pedancy. Adjusting the aperture control doesn't change exposure. Nooo, technically its actually the movement of the aperture blade, which has to be mechanically and electronically controlled by the camera button or dial :)

Great shot. I seen this exact composition, at this location before, but I think this one is better. The one I saw looked like a composite, this is very real with more engagement and better tonality. Love the sky against the rocks with the snow providing a needed tonal balance.

I'm gonna take a Polaroid of my screen. That should be good for another article. Maybe do a pin hole camera next. The possibilities here are mind blowing!

Nice. The perfection in the details are what makes it pop out. The tonality is fantastic. The perfect answer to why we post process instead of letting the camera do the work.

If they added Instagram filters and reduced the price to $200 they'd have a winner.

Why do those 3D images look like 2D one? Because they are really 2D? I don't get it. Is this some type of a joke? Tilt you phone and the images look 3D?

Hypocritical remarks. Sure, he was an idiot, but so are the people driving down the city streets with their cell phones glued to their eyes, 5 feet from the sidewalk where your kids are playing. How many of those have been caught and punished? Set up an uncover task force, slap a few $20K fines on them and that would come to a stop rather quickly.

Personally, this was one of my favorites. Trying to puzzle out how it was made, what it represents, and what I think of it is the stuff great photos are made of. Keep up the great work!

Billiam29: For those that are questioning how the phone could somehow be unlocked, it doesn’t have to be. ‘Lost Mode’ of the Find My iPhone feature places a phone number and brief amount of text of your choosing on the phone’s home screen when it’s activated via the iCloud web site.

Ha ha ha. It displayed a custom message on the screen for one year? Or through telepathy, the owner knew someone picked it up and turn it on at that moment? An there was wireless in the middle of nowhere?

Daniel Bliss: This was the last iPhone before official IP water resistance came in with the 7. It sat outside for 13 months getting rained and snowed on, and still powered right up. That's pretty impressive.

No phone will power up after a year. Not even after month. And the article clearly states it died while recording an hour and a half of video. And do you really believe anyone ever keeps his phone unlocked so a finder can turn it on? I've had two iPhones die due to water spill. No way, no how is this possible. Please, no more Apple propaganda for the gullible.

And who leaves their phone unlocked for any passer by to find? The story is either fake or the details are wrong.

I don't believe. The device powered on when tested 13 months later? No way. My iphone 6 dies after 10 days of non-use. And then later on "while leaving the camera exposed to record the bright blue sky and Sun until its battery died."

So which is it? The battery stay charged for 12 months or it died?
