I have the Samyang 14mm, though have not used it much so far. My first choice would be the Zeiss 15mm, but @ ~$3000 US, my budget wont allow it at this time. I purchased the Samyang 14mm based on reviews at Photozone & some other reviews, and the very nice price compared to the Zeiss 15mm& Canon 14mm costs.Though it is not AF, at this focal length it is not that important. It is a pretty amazing uwa lens. I also thought the Rokinon/Samyang/Bower were the same lenses sold with a different brand name, but see now based on other posts on this thread, there are some differences. They are all about the same cost, at least at B&H. I still would not buy the Canon over the Samyang, but would buy the Zeiss (if i won the lottery). I also have the Canon 16-35L, but prefer the Samyang @ 14mm over the Canon @ 16mm. If you want a UWA lens i would definitly recommend it. I like your photos Dustin, and thanks for the info on the dandelion chip wickedwombat. I will have to check that out.
