I think it's interesting some of the invective being thrown at these lenses. From what I can tell based on the various test I've seen, including these, the lenses are pretty much what you'd expect. Given the OLPF, and the sensor resolution on the X7, they are all resolving about at the limit of what is possible, (the 16mm being the weakest but only in the corners) and frankly, anyone who says they have a $400 lens that outperforms these hasn't done a side by side scientific comparison to prove anything. (and of course that $400 slr lens doesn't have to balance on a tiny gimbal under an aircraft). The only reason the 35mm seems to do poorly here is due to the fact that the shot in question is a whole lot more pulled back than the other lenses, pure and simple. At 100% with a little sharpening, all of these lenses look great, again, given the OLPF.
That OLPF is going to be a point of contention for the stills guys, who've become accustomed to aliased, false detail on previous DJI cameras including the X5s. As the x7 is specifically a cinema camera, that happens to shoot stills, we have to look at the reasons for dji including a stronger anti-aliasing filter in this new camera. (the reason being that aliasing is problematic for moving images and that their customer for the x7 would prefer a system that doesn't alias).
I do believe the lens set for the x7 is overpriced, but not due to quality. It's overpriced mostly due to speed and marketplace. If we're comparing these to Aps-c or 35mm still glass, these lenses should be 400 or less, but given that they are purpose built, lightweight, specific to a niche product like the x7, lenses, it appears that DJI would prefer to sell less at a higher price than more at a lower price. It probably makes business sense, even though it may not make sense to the average customer.
The published MTF charts on these lenses would indicate they are capable of impressive detail. I don't think we're seeing, with the x7, what these lenses are capable of. That will come in a full frame high MP still focused camera, with a less aggressive OLPF.
