• 17:3117:31, 11 January 2021 diff hist +280‎ N File:Sharp london zoom.jpg ‎ A tiny cutout of 160 x 100 pixels (scaled to 1280x800 to illustrate the effect) from File:sharp_london.jpg taken with a Nikon 105 mounted on a Nikon D810. This part of the image is remarkably sharp although it is one the side of the frame.
• 17:2917:29, 11 January 2021 diff hist +470‎ N File:Sharp london.jpg ‎ Picture of London taken with a Nikon 105 mounted on a Nikon D810. The picture highlights various issues on sharpness. The roof at the bottom is too close and out of focus, there are various chimneys that release smoke which ''blurs'' part of the image, and there is a haze that limits the visibility to the distance. However the small cutout File:Sharp_london_zoom.jpg shows that even on the side this picture is actually remarkably sharp.

Compare to File:Notsharp_window.jpg, and look for the arrow. You will see that the wire is clearly visible. Note that this crop is 0.5% of the 45 Megapixel original image. current

This is 0.5% of the 45 Megapixel original image. The arrow points to the wire that runs along the roof, this is the ''soft'' part of the image for the lens. Compare to File:sharp_roof.jpg. current
