I know DX sensors are considered "beginner" or "amateur" cameras because they generally have lower quality than FX sensors. But as technology improves and DX sensors get better quality, I wonder if they could become the new standard for practicality reasons. Lenses for DX can be more compact due to the smaller sensor size, so why do they only make beginner lenses DX only? They could probably make a comparatively compact 70-300 VR if it was DX instead of FX, and it would probably be cheaper too.It seems there's always a premium for FX. Or for the size of the actual Nikon 70-300 VR FX maybe they could make a 70-400 VR DX. Speculating of course.
Anyway, I'm just an amateur so perhaps I am wrong, but anyway, what are your opinions on the matter?
Added (1). @lucienhu - My point is that you can make DX lenses smaller and cheaper. For me to get, say, a 70-200 F2.8 is impractical in price and also it's not a lens you can just carry around, it's very big and bulky. If they made a similar lens designed for DX only, perhaps it could be a little more practical. And same with the 24-70 2.8, which while still useable, is still rather big and is obviously very expensive.
