@infared: Thanks a lot. Yes, time will tell us. So, while the 16-35 is out there, that's a way to go. I wouldn't buy the nikon plus adapter. So I might purchase the classic L WA by summer and see what happens. If I wanna go UW for stars, there is still an 14 f/2.8 MF Samyang at a decent price, to provide as much as exposure value as possible while applying 500/600 rule for moonless nightsky shots.
