Is Nikon 35MM 1.8G better or 50mm 1.8D better?

Indeed, as upstairs said, the imaging difference of the lens itself is not very big. If the deformation must be 50, 50mm is definitely better than 35mm, but this comparison is meaningless.

These two lenses are very cost-effective. If d90 is used, there is no 18- 105 ferrule, and only 35/ 1.8 is preferred. After all, it is a standard field of view of 50mm, and its application range is relatively wide.

If you have condoms, you can give priority to 50/ 1.8, which means you have an extra head. Play fixed focus in the future, and add a 35 head when you gain experience.
