Pentax 21977 DA 18-135mm f/3.5-5.6 ED AL (IF) DC WR Lens for Pentax Digital SLR cameras,Black

A very, very useful lens. Surprisingly, 1/2" shorter than my already-compact Pentax 16-45 f/4! This one, with that 200mm-equiv zoom, is much more versatile. Came from 'Another Deal Site', fulfilled by Amazon... mentioning this because, unlike some older posts below, this lens came in a proper box, with Ricoh warranty cards, an instruction guide AND the lens hood. Exactly as shown on the Amazon page. If I were going on a trip, I would take this lens. Or as the best choice for a walkaround-town snapshot lens. Amazon calls it 'discontinued', which is confusing, since, as of today June 9 2015, it is also for sale on the Ricoh lens web page, though at $500. It is well-made, works perfectly and immediately with my K-5 IIs, and my older K-01. Does it take good pictures? Sure. Tell you a secret though... ANY modern lens takes great pictures... re sharpness and color rendition. What we are really buying is ergonomics... how easy it is to use the lens for a hurried once-in-a-lifetime snapshot. And that gets you over to the camera... and Pentax DSLRs... all of them... have excellent autofocus if there is any light at all in the scene, any contrasting area you can use as a focus point. This 18-135 WR also lets you focus manually with a lens ring, without having to turn off autofocus. Best of both worlds. Lastly, the WR means Weather Resistant. No, you can't take it surfing, or in a pool. But it is rainproof, and dustproof, and sandproof... particularly if you are using it on a recent Pentax weather-resistant DSLR, like the K-3s, K-5s, K-30, K-50, etc, etc. So few photos are taken in the rain... but you can!

I bought this lens as my one and only bad-weather zoom. Physically it is about the same size as my 18-250mm Pentax superzoom, but for what it loses (100mm plus of zoom at the long end), it makes up in the comfort of knowing it's weather-sealed, and I can face light drizzle with confidence and downpours with the knowledge that if I get inside soon enough, my camera and lens will not be destroyed or shorted out. Thus far I am quite happy with it - it offers enough focal length "span" for the tasks I bought it for (wide enough at the wide end; tele enough at the other), and more than adequate image quality. Handling is good, and manual focus override is quite reasonable with "quick shift" - the MF ring is nicely damped, making manual adjustment easy, or if you're moving from near to far objects (or vice versa) you can give the focus ring a twist and let the AF do the rest of the work. The inbuilt DC motor doesn't seem notably faster than screw-drive, but it is accurate when lighting is adequate (see below) and is generally much quieter where this is important. The lens is advertised as being incompatible with some older digital bodies (all *ist-D... series, K100D, K110D) as they do not support the inbuilt autofocus motor, so take care if you are buying a cheap body and this lens separately second-hand. The only problem I have had with it is I've had trouble locking focus sometimes. However, this has always occurred in quite low-light situations, where variable-aperture zooms like this one aren't at their best without strong focus-assist from an external flash (which I don't have). It really can't really be put down to the lens, which I seem to be pushing to its limits in low light on the K-5. If you can only have only one lens on your Pentax DSLR, this is a good choice, especially if you are travelling to wet and/or dusty places and don't want to fiddle with lens changes much. It doesn't give quite the range that the 18-270 does or quite the image quality that some of the other higher-end lenses do, but the weather sealing makes it an excellent practical choice, and if you use it well it will give you excellent results for amateur or enthusiast work. Especially if you're just getting into DSLR, this lens as part of a lens-body deal is an excellent option and will keep you going for quite a while before you need to consider anything else.

Ich habe für meine Pentax K 30 ein Zoom-Objektiv mit realtiv großem Zoombereich gesucht, dass auch noch abgedichtet ist. Also bieb eigentlich nur das 18-135 mm übrig. Meine bisherigen Erfahrungen damit: Top verarbeitet, schneller und leiser Autofocus (der stellt wirklich blitzschnell scharf und immer auf dem Punkt). Das Objektiv hat bisher meine Erwartungen voll und ganz erfüllt. Die Abbildungseigenschaften habe ich jetzt nicht akribisch getestet, wenn ich mir meine Fotos so anschaue, dann genügt das meinen Ansprüchen voll und ganz (meist Darstellung über HD-Fernseher mit 55" Bildschirmdiagonale). Nicht so begeistert war ich von der Verpackung: Das Objketiv wurde in einer einfachen Schachtel aus Pappe geliefert. Ich hätte wenigstens einen Objektiv-Köcher erwartet. Ist aber momentan nicht so wichtig, da ich es derzeit als "immer drauf" Objektiv nutze. Könnte sich aber mal ändern, wenn weitere dazu kommen.
