Maybe you people can answer this simple (not so for me) question.
Why Nikon (NEITHER THE OTHERS) didn\'t make the DX lenses according to the \"standards\" and most used focal length that we used to put in ours 35mm cameras.
In other words, I think it would be better for all the DX users, to have accsess quickly and without any calculations, to the legendary focal length that most professionals are familiar with.
ej.24mm, 35mm, 50mm and 85mm 105mm etc.
In fact, Nikon didn´t make DX prime lenses at all.
Hope you understand my poor english.
Thanks from already!

| Nikon has just released the 35mm DX lens, they also put out the 10.5 mm prime, so Nikon has released two primes in DX format. I think that Nikon and other companies don't make a lot of primes in DX or APS-C format due to the fact that they are counting on pros using a full frame camera and market the slower lenses for the consumer. With that being said, Nikon and ther companies have made zooms for their respective format that are fantastic. The first one that comes to mind for Nikon is the 17-55 2.8. Very sharp lens and its fast. the conversion to what you would call "normal" is very simple, its either a multiple of 1.5 or 1.6 for Canon. Really not that hard at all. |

Well, I'd venture to guess part of it is that they were already good at making those focal lengths, so less R&D was needed to put out lenses of the old focal lengths, instead of creating the "adapted standard" lengths.

I think that their initial intent was to have DX be more affordable and thus "consumer" camera. Casual users prefer zoom lenses because they cover a wide range of focal lenghts in one package. Primes are more serious or "professional" camera users who may gravitate more towards the full frame sensor bodies. The quality of APS-C cameras have improved quite a bit and so has the range of people using them so now there is finally enough demand in their opinion to warrant releasing prime lenses for the DX camera. Another potential reason is that until recently DX cameras had internal focusing motors which would allow anybody who really wanted to to use any of the 35mm camera lenses including primes on their DX bodies if they wanted. Newer DX bodies lack the motor so lenses have to include them or be used manually. All of this is purely my own speculation.
As for what focal lengths to choose for making primes, you need to remember that due to the "crop factor" on DX, the most popular focal lengths are not the same. The 35mm is no longer a wide angle but more of a "normal" lens and even 24mm is not very wide but closer to the field of view you found on the 35mm lens. I would expect that Nikon is working on more prime lenses for the DX system- they are just not released yet.
