as above - i was wondering which would be a better option in terms of IQ. as for the cheapest UWA, the one i've come across is the opteka 6.5 or the samyang 7.5mm. sadly, i don't really like fisheyes (prefer rectilinear), but also don't wanna spend a big bomb on the 7-14 or 9-18. any other cool and cheap lenses to recommend then? (doesn't matter if it's manual, as long as IQ is decent!) i could explore using a canon adapter to my canon UWA lenses, but that defeats the purpose of using my E-PL5 - portability. so that's out of the question. another alternative is just to get the samyang fisheye, and then defish in LR. then my question would be - how effective would the defishing be (i.e. how well can it restore the photo to rectilinear style and how much would it eat into the corners) and whether it can be made automatic in LR? thanks!
