1 Down. 1 more to go? (Maybe)

This is the exact set of lens' I want.. But iono if im down to drop so much $$$ on another lens.. But I just wanna complete my set cause the shitty part about having one of these is that no one is gonna buy it if you get sick of it so to get un-sick of it you gotta buy more shit lol.... So maybe when I get better at working this thing or I get really really bored with it ill start saving up.
