I would've gotten all three. Smile (my wife still has her NEX-3 but the charger is long gone... not sure if she can find it).
The 10-20mm is interesting. They gave away stabilisation for power zoom, which could make sense given that recent bodies have IBIS and stabilisation is not so critical for such a wide lens. Maybe a bit too expensive - let's wait and see the price in a couple of months...
The 15/1.4 has 8.6% barrel distortion in RAW, and therefore is close to being named "the first f/1.4 Fisheye lens in history". Big Grin
At least Lenstip says so (they've reviewed this lens posthaste). I get the feeling the 11/1.8 is not going to be pretty in this regard either. Smile
LOL.
Anyway I seee that these three lenses are mostly for vloggers, so they won't care about strong in-camera corrections...
I know I would've gotten the 11mm in a heartbeat if I had been an (active) user of Sony E system (or Nikon Z, lol). And I don't even know for certain what vlogging is. Big Grin

8.6% is indeed a lot, but what we can observe is that its IQ is impressive, even in the corners.
I'm no optical engineer, but it appears that taking advantage of software correction allows to either:
  • build smaller lenses with the same IQ than fully optically corrected ones
  • build similar-sized lenses with better IQ than fully optically corrected ones

Software correction probably allows for more freedom in the design and in the end, what matters is the final result and I'm perfectly fine with this as long as any software can access the lens distortion data to correct for it.
Not sure if Lenstip's resolution measurements are done with the distortion correction turned on or off? This point has eluded me when reading their review. If it's off, I think there is going to be the second side to the story, and it may NOT be pretty.
They posted both diagrams (correction on and off).
Here we go with the 11mm: 9.6%...

Practically no LoCa; coma instead could be a problem for astrophotography; very good behaviour with flares.
