I'm looking at the samyang/bower/rokinon 14mm and 24mm lenses and wondering if others have used them and what you think? I've had the canon 16-35 2.8 on my list as I love lightpainting and want to do stars as points so need the 2.8. I've read quite a bit about the samyang and realise its all manual and that doesn't worry me as lightpainting is all manual anyway as lots of you know.
the thing is that the canon lens is about $1700 and the samyang 14 about $490 from local suppliers. with the canon lens at $1700 I could buy the samyang 14mm and the new canon 16-35 f4 for about the same money.
I know that the samyang has moustaching but I've read where its very sharp and beats the Canon 16-35 for coma on stars.
Does anybody have any experience with these lenses over a period of time? And does anybody have a view on which of the 14 mm or 24 mm is the best focal length?
