Hi, I'm looking for a wide-angle lens (Canon APS-C) and was considering either Samyang 14mm or Tokina 11-16/12-24. There are so many threads here already, so it's probably ok to ask in this topic instead of creating yet another one.
The only "problem" with Samyang is that it doesn't accept filters. I've read somewhere that they're actually gonna release a "filter mount kit", but it was going to be for those big rectangular filters and the pics of that kit looked kinda scary (big and hard to attach). Anyway, since I'm not planning switching to full frame, Tokina is fine, I guess. I'll need WA for landscape photography mostly and 12-24 looks more interesting, but the main question I've got is about those heavy CAs. They are usually fixable in post production, but the filters I'm mostly interested in are Neutral Density ones, for those long exposures.. so, when you expose for like 10 minutes, what happens with those chromatic aberrations? I mean, won't they ruin the picture?
For example, I shoot a field of grass, and in a normal shot there are CAs in transition areas (grass/sky). But what happens if the exposure is ~10-12 minutes, the grass is moving all that time and... will I end up with a (unfixable in pp) purple/greenish mess instead of lovely blurry grass? <img src='http://forum.photozone.de/public/style_emoticons/<#EMO_DIR#>/unsure.gif' class='bbc_emoticon' alt=':unsure:' /> Because if so (= ND filters aren't usable with a lens producing such heavy chromatic aberrations), I'd rather get almost 2 times cheaper, sharper and faster Samyang 14mm. So, how will those CAs look in a 10 minutes exposure? And, on topic, do you plan testing Tokina 12-24 II? <img src='http://forum.photozone.de/public/style_emoticons/<#EMO_DIR#>/rolleyes.gif' class='bbc_emoticon' alt='
