[QUOTE="WayneF, post: 223616, member: 12496"] 60 mm is f/2.8, this 50 mm is f/1.4 (which is two stops difference) 60 mm is telephoto on DX, 50mm is slightly less telephoto. 60 mm can focus to a couple of inches for 1:1 magnification. 50mm cannot get that close. Do you have a FX camera? 50 mm was considered the "normal" lens on 35mm film cameras (FX). Normal width of view (on FX), deemed important because its view sort of matched the view the human eye thinks it sees there (on FX). On DX, it is a telephoto view. 50mm is mild telephoto on a DX camera. Indoors, imagine you wanted a picture of four people on a couch. Being telephoto, your room size may not permit you to back away far enough to get all four in the picture view. Try this with your zoom lens set to 50mm, to see the effect. Often, dim views are indoor views (limited space). Anyway, 50mm is deemed important for a couple of reasons. It was a normal lens on FX, however it is telephoto on DX. "Normal" was a concept in the old days, before zoom lenses. It was the one you needed most. Zoom lenses cover many more situations. One version is f/1.8, which zoom lenses are not. And the f/1.8 was about the least expensive lens, for a long time not much more than $100 US. The f/1.4 is much more pricey, and is only 2/3 stop wider. The depth of field will be very small at such apertures. But the f/1.8 is a very sharp lens at more nominal f/stops. It just cannot zoom for other situations. The 35mm f/1.8 lens would be considered more of a "normal" lens for DX. [/QUOTE]
