Anyone been looking for a pentax lense recently only to find that all of the reputable dealers (B&H, Adorama, etc) are back ordered and/or out of stock? What's up w/ that? Was there a massive recall or a massive demand all of a sudden or something? They have plenty of kit lenses or lesser quality ones, but the better ones are all gone. I've been looking for a wide 28mm prime or a wide zoom like 28-90mm but can't find anything. I did see adorama has a 28mm soft focus, but it's like $120 more than the standard prime 28mm. Is soft focus worth that price differential? I was considering Tamron or Sigma, but a lot of the reviews I've read keeps talking about people getting a bad copy and having to return a few times until they get a 'good' one. I think I got a 'good copy' of the 70-200 f/2.8 sigma but doubt I'll look for another sigma. So any one know what the problem is w/ the stock of pentax lenses?
