Nikon seems to continue the upgrade their line of primes, first one out was the 50mm/f1.4G AF-S and now Nikon announced a new 35mm the 35mm f1.8 G AF-S DX.
Found a post on DP Review to CNET's web page: http://news.cnet.com/
35mm on a DX camera will give the focal length of 52mm, regarded as the "standard" focal length since it's closest to the vision of the human eye.I have the Nikon 50mm/f1.8D that's a nice fast lens but it's a bit too much 'tele' for my taste to be used more regularly. Not sure I'm so found of the "G" that means there will be no manual aperture ring. Price is supposed to be around $200, we'll see what it will end up when the lens hits Sweden. Will keep my eyes open for reviews on this one...

What's so speedy about those lenses? Or do you mean fixed? :D
ReplyDeleteThe lower f-number is the 'faster' they are. A f1.2 is faster than a f2.8, and it's possible to calculate haw many f-stops faster it is.

When people talk about an fast lens, what does that mean?
ReplyDeleteLenses are referred to by their maximum aperture (that's the biggest hole, the smaller number). Thus, Nikon made (at least) three 28mm lenses at one point, a 28 f/2.0, a 28 f/2.8 and a 28 f/3.5. All three of these lenses had f/4, f/5.6, and so on up to f/16; they were distinguished by the maximum amount of light they could let in. The 28mm f/3.5, one of which I own, when set to its maximum aperture of f/3.5, lets in one third less light that the 28 f/2.8. The 28 f/2.8, in turn, at its maximum aperture, lets in only half the light of the 28 f/2.0 at it's maximum aperture. Lenses which have wide maximum apertures and let in lots of light are called fast lenses. Lenses which let in comparatively less light at their maximum apertures are called slow lenses. The 28 f/2.0 would be a fast lens; the 28 f/2.8 would be sort of regular, for which there isn't really a name; the 28 f/3.5 would be kind of slow.
Ah, what we call lightstrong in Sweden. :D
ReplyDeleteLightfastness is a fun word, but totally unrelated. :D
