I was more thinking of something longer or wide than the 5-15mm. I think that this zoom lens is pretty good already so users may not be overly interested in something that overlaps here.
I haven't really seen something wider other than fisheyes. There seem to be a couple of good (on paper) 25mm and 35mm lenses.
However, I'm clueless whether -say- of the Tamron SP C-mount lenses is really decent. I reckon that most are as old as time itself. The Fujinon HF-XX-SA series seem to be rather attractive as well.
