Quote:Polarisers at such wide angles? Even at 24mm there is usually a very obvious sky gradient effect when used outdoors, unless there are other applications where this isn't a problem?Not sure why you say this. The sky is only a problem if you over rotate the CPL. In any case polarizers are needed if you want to redue reflections. But more importantly, without a filter thread it would make working with high ND filters a pain.
Having said this, I want to use this lens for night photography, so filters are not such an issue. For me, the lens needs to be good to great at f1.4.
