I got a dud

Jessica Heaton, Amazon
11 July 2013
  • Summary: I bought this lens through a well-known used camera distributor, so I thought the AF problem would have been checked out and fixed. Nope. Towards the end of the zoom range, it could not find its focus. It would front focus, then back focus, over and over until it seemed to just give up. I loved the image quality and everything else about the lens, but I can't have a lens that won't focus.

Disapointed considering the hype

  • Excerpt: Being a Pentaxian I had great hopes for this lens. Considering the ratng and the hype I was very excited to buy this. Expecially since I am shooting both a K-7 and K-5 bodys. This lens failed over and over again. I sent it in to Pentax for warranty service 2 times and each time they found nothing wrong and sent it back. Finally I gave up and traded it in for a Sigma f2.8 70-200mm HMS lens. Much happier with Sigma.
  • Cons: Blurry Focus, Slow Focus

Great Outdoor Lens! (updated March 2nd 2012)

  • Summary: When I first got this lens, my initial thoughts were "wow, this thing is gorgeous". I love the gold highlights, the green line near the mount, and the massive zoom and focus rings. The large front element makes this lens look like it means business. This thing looks fantastic. On my K-7, this lens is perfectly balanced. The large zoom ring means the lens has a wide range of space to support it, so I suspect it would be well balanced on just about any Pentax camera.

SDM Failure

A. Arena, Amazon
24 January 2010
  • Summary: I would guess that most people that review this lens do so just after they buy it. If I wrote my review then I would have loved it as well. Now just after it is out of warranty, the SDM failed. (SDM failure is becoming a common problem with Pentax). Pentax sent me a replacement, and after 1 month of use, the SDM failed on that lens as well. I will not buy any more Pentax lenses with SDM.

Nicht zufrieden

Ohara, Amazon
28 September 2012
  • Summary: Habe lange überlegt ob ich mir dieses Objektiv zulegen soll. Letztendlich doch bei Amazon bestellt. Von der Haptik, der Verarbeitungsqualität und der Schnelligkeit des Autofokus hätte das Objektiv 5 Sterne verdient. Heute nun raus mit einem Model zum Shooten, Gott sei dank einfach nur mal um das Objektiv zu testen. Schon beim betrachten der Bilder auf dem Display der K5 fiel mir irgendwie eine leichte Unschärfe auf.

  • Conclusion: Första intrycket mycket bra Har tagit några testbilder och bildkvaliteten verkar helt efter förväntan. Gediget bygge som utstrålar kvalitet. AF:en kunde varit snabbare Speciellt bra att objektivet inte ändrar storlek varken vid zoomning eller fokusering man slipper att det sugs in en massa damm. Komplettering 2013-09-24: Efter att objektivet legat oanvänt drygt ett år tänkte jag "damma av det" och då upptäcker jag att autofokusen inte längre fungerar som det skall.
  • Pros: Skärpa, kontrast, IF, kvalitetskänslan
  • Cons: AF inte speciellt snabb. SDM är felbenägen på äldre modeller av det här objektivet.

Vermutlich bestes Zoom für Pentaxianer.

  • Summary: Zuerst einmal: Von der Abbildungsleistung her ist dieses Objektiv m.M.n. nahe an Festbrennweiten dran, daher möchte ich an dieser Stelle eher die negativen Punkte schildern. Es ist offenblendtauglich und nur bei 135mm/2.8 etwas weich (offen!). Der verbaute SDM (Ultraschallmotor) ist sehr angenehm, wenn auch durch die Mechanik nicht ganz lautlos.
