>>3736126>>3736157>>3736161No experience with j12 but in my research it seemed like you could get a great one or a shit one. The skopar is the best bet. The canons are an option but aren't much cheaper at all than a skopar and you're stuck with 40mm filters which are IMPOSSIBLE to find. The easiest stepup rings to find are 40 to 40.5 which is a nearly equality stupid filter size.
