Color cast: Here I fear that the SK cast on the 160 is severe enough it could be un-usable on the 180 -- your thoughts?
Without a CF i tend to agree with you. I do have the magenta on the sides as you can see with the safe zone of 8mm and my fear the 180 will go much deeper with that magenta cast and we could start introducing some bad stuff. I wish i had one here with me but Jack i think the Roadie is the safer bet for 180 users. Honestly either lens is awesome but for 180 users without a through test and CF go the Roadie is my advice. I really have no dog in this fight and trying to decide myself. I'm leaning to the SK but I seem to be okay with my 160 unless someone is seeing something crazy let me know . This is big expense.
