The following pictures are near-to 100% crop from shots with D800 + 16-35 F/4. Click each to magnify.
Walking towards to “golden horn“
The Galata bridge and tower
The “Bosphorus fires” at sunset
The Ataturk bridge
The Suleiman Mosque
For example, the first picture of this post is cut out of the below one.
Cropped pictures showed here are not as crispy as with a zoom (the mounted lens is the Nikon 16-35 f/4 wide-angle), but they are still better detailed than the Nokia Lumia examples you can find here . Of course I should have had both cameras at hand in the same moment… but it is clear how useless the 100% crops from Nokia are, unless light conditions are optimal like here. Pity, I thought a Nokia Lumia 1020 could have been useful when my back refuses to carry the D800.
