>>3496000I was just mentioning Z-mount lenses since they use the same technology as AF-P lenses, not saying that he could put some on his D3100 (disclaimer: I have a D3100 and a Z7).
The AF-P DX lenses are much better than previous DX kit lenses (not that hard to be honest) but yeah, the only nice one is the FX 70-300, which is much better than the AF-S one that quickly degraded past 200mm.
Here's a 100% crop taken with a Z7 and AF-P 70-300 at 300mm (not mine, from someone on DPReview)
