  • I'm not sure if pentaust has a K-1 and one of the D FA* primes - I have the D FA* 50mm, and I'll assume the 85mm is similar. AF works as well as I could expect. Misfocus can have many causes, ...
  • Actually they didn't bankrupt themselves but indeed, the strategy of making less expensive products hurt them badly - we're seeing the effects even now. I mean, things like the long break in making ...
  • Medium format is a bit different though. The lenses are often slower but the format compensates through sheer size. Best means the best they can make and still sell, hopefully for a profit. What's ...
  • You know what is funny? When Pentax had only medium aperture lenses, those weren't "good enough". Now we're told the D FA*s are "too much"? The * line is Pentax' best, and "large aperture" is one ...
  • Optimist about the bad theory, realist regarding new models. The "profile bits" theory never made sense, for obvious reasons. It still doesn't. But you have the opportunity to test it... further ...
  • Thanks. I don't find it surprising though... the new firmware is for "optimizing performance", compare that with "Corresponded to [KAF4 lens mount] that is equipped with an electromagnetic ...
  • Nice! I admit being somewhat jealous, but I'll get mine one day... Alex
  • Replied in On retirement.
    Don't lose faith now, when Ricoh Imaging shows clear signs that the APS-C flagship is nearing production. Here's the presentation which was supposed to be made at CP+: https://www.youtube.com/watch ...
  • Pentax is safe, now... good things are happening. Quickly, convince him to jump to another brand - then Olympus will be saved. Alex
  • Welcome! I hope you'll enjoy your stay... as well as your Pentax gear. It's a good choice - landscapes, I see - although I have none of the FA Limiteds. I can't wait for the D FA 21mm Limited, ...
  • The 15-30 is a modified Tamron, made in Japan's Tamron factory. The 24-70 and 70-210 are also modified Tamrons. But all Pentax lenses are made in Vietnam, for a while. That's not something bad, ...
  • Heliar, my K-5 had the oil on sensor issue... it was promptly exchanged by Pentax.
    I remember very well, they addressed this very...

  • Just don't expect it to focus fast, it uses the old style micromotor SDM - you can see it next to the D FA* 50mm f/1.4's ring type SDM: http://www.ricoh-imaging.co.jp/japan/products/star_lens/speci ...
  • That's about it... perhaps the DA* 55mm f/1.4, although officially an APS-C lens (check before if it works satisfactorily on FF, I haven't tried it myself). But I would rather get the D FA*. In the ...
  • Replied in Re New 85?
    Nonsense! At nearly 1.3kg this lens is clearly heavier than a duck, thus it cannot possibly be a witch! Alex
  • Distortion is not influenced by the ISO, nor shutter speed. Alex
  • Maybe, but it's logical and consistently fits in what we know. Except for Mr. Kimio Tanaka sharing what he found out from Ricoh, you mean? Why? It's perfectly possible. No, that's not what they ...
  • It's actually quite to the point and precise, without entering in any detail. The K-1, K-1 II and K-3 had an issue needing to be fixed by a firmware update. The K-3 II and KP didn't. Alex
  • Let me rephrase that. Why do you assume vignetting wide open as being the reason for the K-1 and K-1II firmware? (with the K-3 being an exception, to make it work) Bingo! For these 3 cameras - K-1, ...
  • And on that day, there will be complete silence on this subject, while I will be "wrong" about another thing :-p By the way: http://www.ricoh-imaging.co.jp/english/products/star_lens/special/sp_dfa ...
