Thanks JK, I wasn't thinking of larger, to my idea it's way too big...
Looks ok to me on screen, Robert.
I've got an iPhone 6 and have used images in a photobook ok...(not full page of course!)...though I can see the difference.
They are lacking in edge contrast (I suppose that's another way of saying unsharp mask) but they won't take the amount of sharpening to lift them to DSLR level. For me the biggest contributor to loss of clarity is how we hold the device.

We all learnt that for handholding, the shutter speeds should be faster than the inverse of the focal length of the lens. We soon learnt more, in that sensor size and pixel density all impact on this formula, as does how we hold the device. Greater pixel density needs faster shutter speed.

On the recent trip with Graham and Mike to snettisham, both mike and I took some videos. The one I posted was Mikes shot on his Panasonic FZ1000. I wouldn't dream of posting my versions! Despite using a 'better' camera and lens combination, holding the camera and long lens at arms length whilst viewing the back screen created footage we would all get sea sick after only a few minutes. Atrocious!

Mike was holding his mirrorless camera up to his eye and achieved far greater stability.

Yes I could/should have used a tripod. You know, those aluminium/carbon fibre/metal things with legs we leave at home or in the car. 😆 

My point is this....I think if we braced ourselves and supported the iphones we would get much closer to DSLR quality. It's technique that lets us down when we stray from traditional camera hand holding.


Just looking at the exif ....did you or the phone choose those settings?  F2.2@1/1202th and 25iso, using a 4.2mm lens.  It shows the dof benefit of smaller sensors and wide focal lengths.
