and the license lasts for a lifetime!), and i easily get rid of the CAs in PS or CNX2, for example. The character of the bokeh is rather pleasant in most cases but it has a tendency to produce rough-looking details when you give it things that will trigger it such as twigs and foliage. Stopping it down to about f/4 helps but you’ll lose a lot of blurriness as a trade-off for cleaner-looking blurs. When used wide open at ƒ/1.8, the 18.5mm produces corners in images which are 2/3 of a stop darker than the center. Stopping down to ƒ/2.8 or smaller reduces this to below a quarter-stop, or negligible. Starting from diaframa 11, the sharpness dops off visibly, due to diffraction. No problem: because the depth of field of the Nikon 1 system is large, you don’t have to stop down any further than f/8. See Nikon Lens Compatibility for details with your camera. Read down the "AF-S, AF-I" and "G" columns for this lens. You'll get the least of all the features displayed in all columns, since "G" ( gelding) is a deliberate handicap which removes features.

The build quality of the lens is very good. It's based on a metal mount, while the lens tube feels more like plastic. Three times the price, but ten times the range - the 10-100mm also offers VR. The 18.5mm prime is sharper and offers the faster working aperture of ƒ1.8; however, the zoom lens gives you the convenience of multiple focal lengths. Otherwise, the 10-100mm is similar when it comes to distortion, corner shading and chromatic aberration. First off, those reading this review that are not familiar with the Nikon 1 system may not know exactly what this lens is. The 1 Nikkor 18.5mm f/1.8 lens is for Nikon 1 CX format cameras only. The Nikon 1 camera has a small one-inch sensor that you must multiply a given lens focal length by 2.7x to figure out the exact focal length. So this 18.5mm lens is a 50mm equivalent standard f/1.8 lens. Bokeh: I’m not impressed by the bokeh of the lens. The aperture blades in my sample don’t make for a perfect round on out of highlights, and it tends to produce a considerable amount of longitudinal aberration, as well, even stopped down. As a full-frame lens, I will be reviewing it as such. You may make the usual inferences for DX. It will work fine on DX cameras, but it's foolish to use it on a DX camera because the 18-55mm VR gives better performance lot less money on DX instead!

Autofocus is a bit slower than I'd expect for an ultrawide, but as an ultrawide, still plenty fast.

Neither Canon nor Nikon make any sharper ultrawide lenses than this. The 18-35mm G also has very little light falloff. This lens does not have built-in image stabilization. In view of the high brightness that’s not so bad. Since today, i got a 2nd V1 Body, because i got it in excellent condition at a bargain price, and today also

Since this is basically an 18.5mm lens with the field-of-view that mimics a 50mm lens you’ll get loads of distortion as expected. It isn’t the best tool for taking photos of architecture or anything that requires straight lines to remain straight. Linear Distortion: A surprising amount for a “normal” lens: about 2% (barrel type). The good news is that it is a very straightforward barreling, and not a more complex type of distortion as we sometimes find these days with lenses that have aspherical elements, so easily removed. Still, when you remove 2% distortion you lose some pixels, and some of the Nikon 1 models (e.g. first generation) are already low in count to start with.
