340 KB | A close-up using the Nikon 28-300. The minimum focus distance is about 50 cm, so this lens let's you come quite close. But the real beauty of this picture is, how easy it is to get it. This is a handheld picture at <kbd>1/40s</kbd>. Two out of three shots I made in this sequence are this good. Sure you may find issues with the picture and complain about its sharpness, but you will appreciate this lens if you work with it, how easy it makes life for you. | 1 |

452 KB | My room highlighting the quite large poster in the background. This is a 2meter poster and the picture File:Poster picture.jpg picture is actually a 24 Megapixel image which is not even particularly sharp, but works well in the room.

298 KB | Picture of the gorgeous courtyard of the British Museum in London. Picture by a Nikon 10-24. There are a couple of things that make this wide angle work. I am taking this picture from the second floor, so I can hold the camera straight. Second the center image has practically a cylinder so the distortion is not so visible and third, the interesting part what you see is the great roof design by Norman Foster that already has a funny shape. If you were to look at the people on the edges... | 1 |

161 KB | A lighthouse in the Azores shot by a Nikon 10-24 at <kbd>f/5</kbd>. This is the same camera/lens used for File:6881_dirty.jpg where you can see how dirty the image sensor is.
