Summary: Superb lens quality and good construction. However, after three years and just few times used (around 10 photo sessions), the SDM motor stopped. I had to send it to repair. Now I have to use it with the screw motor from the camera.
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.
Summary: My oldest auto-focus lens is a 300 mm f4.5 EDF lens bought in 1988. I have used it in deserts, rain and over rough terain so it have taken a few knocks and looks like it's been through the wars but still works as well now as it did when I first bought it, so on the strenght of this I bought another...
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.
Summary: This lens is as sharp, and powerful as others have stated... the bokeh is incredible. I have a K10D, and I only use this lens outdoors... I've been unimpressed with it indoors when compared to my 50mm prime.
Summary: I have had this lens for just over a year. I love everything about this lens except for the fact that I've had to send it in for repairs three times. The auto focus motor (SDM) just simply doesn't work. I don't use this lens all that much.
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.
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).
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.
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.
Pros: Skärpa, kontrast, IF, kvalitetskänslan
Cons: AF inte speciellt snabb. SDM är felbenägen på äldre modeller av det här objektivet.
