Do amateur photographers need macro lenses besides 18-200 lenses?

If you are really interested in macro photography, you can consider AFS 105 F2.8 VR, the price is about 5000, and the effect is not too expensive. I recommend buying this lens myself, but I don't use it much.

Then there is Longteng's sp90 F2.8 macro, which is also very famous and works well. Of course, it is similar to 105VR, and the price is about 3000.

Then there is the af 50 F2.8 macro, which is generally famous. The AF 200F3.5 macro is more expensive than 105VR.

There is also afs 85 micro, a professional DX format with low cost performance.
