Hi KrisAK,
first of all, it‘s not „he“, it‘s me 🙂 My fault, I should have written „my thoughts“… it‘s my blog…
And yes, of course the vignetting is made in post, that‘s very often my style. So I don‘t care about vignetting, but both are OK in this respect - the f/1.4 even better I think.
Coming to the size: Puh, yeah, it‘s OK… but as I wrote, I would like it to be a bit smaller. All in all, though, it's still OK, as it's also quite slim and light.
Should you prefer it to the F2 version? This is the hardest question of all. As a landscape photographer probably yes, otherwise it depends on how much you need/want that kind of perfection. It's damn good without question, but I'm still not selling the F2 either... maybe that answers the question best.
Cheers,
Peter
