The APS-C sensor in Nikon digital SLRs has a “crop factor” of 1.5X. Wildlife shooters immediately liked the idea of their 200mm lens having the same angle of view as a 300mm lens.
While the gains in apparent focal length on telephoto lenses were praised by nature shooters, the downside of this “crop factor” was that now your 17-35mm lens lost its “super-wide” ability and became a pedestrian 26-52mm lens.
Many early adopters of digital flocked to their local camera shops to purchase the large (and rather expensive) 14mm Nikkor lens. At least then they had an effective focal length of 21mm; wide enough for some, but not truly “super wide” on a DX format body...Full Shootout...Here
