So i went FF and sold off my crop uwa. now i didnt use it much but it was deff nice to have. so question is, whats a good UWA lens for a 5d? now i dont need AF or a super wide apeture. so id be ok with an older MF lens with and adapter. i dont need L quality as ill only use it ever once in a while but decent quality would be great. im looking for something under 200$ but if id have to id go higher it be ok. Oh and zoom isnt that big of a deal if there is a 17mm prime or something that would work...any input would be great!
