Originally posted by bossa could you indicate if these lenses were bought locally through a store new or used via eBay and/or if they were parallel imports?
I'm not sure why it's relevant, but for the record....
FA77 new from a B&M store in Adelaide.
DA40, DA15, DA21 and FA31 new from B&H or Adorama in three separate transactions at opportunistic prices in the first quarter of last year.
FA43 and DA70 second hand via the Forum marketplace a couple of months later.
They have all been great lenses. The only two I would consider moving on (but I'm happy to keep specifically for the K-01) are the DA40 and DA70, not because of poor performance but simply because I prefer the rendering of their FA brethren.
