I'm looking for a cheapish wide (<10mm) angle lens for my OMD. It would mainly be used for landscapes so I don't really worry about having auto-focus, manual will do just fine. I think the Samyang could be a nice cheap option for me but I'm worried that it may have too much distortion to give natural looking landscape shots. Does anyone want to weigh in with their experience with this lens. If anyone knows how it compares to something a bit more expensive like the Olympus 9-18mm that's be great to hear?
