Questions & Answers

RANDY U : Does this lens have vibration reduction?ALEXEI B : No it doesn'tALEXEI B : noCHUN L : No vibration reduction function from lens. But the Pentax camera body have vibration reduction function.RICHARD A : Pentax calls it shake reduction. This lens does not have shake reduction. In fact no pentax lenses have shake reduction because pentax puts shake reduction technology in their cameras so it is not necessary to have it in the lens.This is different from Nikon and Canon who put anti shake technology in their lenses. Hope that helps.RICHARD B : no, the lens has no shake reduction (also called image stabilization), because it was made for the Pentax camera body with built in shake reduction stabilization, like the K-5 has. The camera's sensor has the image stabilize system, so any lens without image stabilization (that mounts to the Pentax body) can be used and so will have the shake reduction benefit. I hope this explains it.DONALD W : Pentax lens do not have vibration reduction. The vibration reduction is in the camera body so therefore all lens actually have vibration reduction that are attached to Pentax digital camerasSRINIVAS G : For all Pentax cameras the Shake Reduction (Vibration Reduction) is in Camera bodies. This is Pentax philosophy. This way all lenses that you mount on Pentax cameras will have Shake Reduction. So far there are no Pentax lenses with shake reduction for the same reason. Even their latest APSC camera K3 II and their full frame camera K1 have the shake reduction built into their bodies and not in the lenses. Pentax calls the vibration reduction as Shake Reduction abbreviated as SR on their camera bodies. This is their branding. Trust this clarifies.BURTON G : Yes it does, I am an older person who tends to shake and the pictures come out very stable, no blurring from shaking. I hope this helpsERIC B : the Pentax vibration reduction is done in the body of the camera so none of the lenses fir this camera have or need shake reduction. this makes the lenses cheaper and lighter, the best of all worlds.KENNETH M : No it doesn't, Pentax camera bodies have in-body shake reductionGARY W : I've used this lens on my K5 but have now switched over to Canon. The lens does not have vibration reduction however many of the newer Pentax bodies have internal vibration reduction built in.PAUL N : No, Pentax relies on the VC to be built into their cameras and not the lenses.DAVID D : I assume you mean "Shake Reduction"? Pentax cameras have this feature in the camera body so there is no need to have it in the lens. So every lens you use on a body with "SR" (Shake Reduction) has the advantage of this feature. This is one of the things that sets Pentax apart from the other manufacturers, also give you more bang for your buck in a lens.
Shopper : I have a Pentax K20D with a Pentax lens of 18-250 zoom. I am looking for a doubler that will fit the camera and lens. Any recommendations for an auto zoom doubler?PETER M : Bower 2x Af Mc7 Tele Converter Teleconvertor Doubler For Pentax Pk Digital Slr CameraRALPH Z : From what I have heard and read, auto zoom lens doublers do not work so well with digital cameras and lenses. If this doubler idea were to be true, then the lens manufacturers would be supplying the market with proven items. Especially by now since digital cameras have been on the market for quite a few years.MICHAEL T : I bought the K-5 with the 18-135 and 55-300 in January. We used the camera during a month long trip to India in February. The 18-135 was the perfect utility lens. We used it for 95% of the photos. We love the lens. Buy it!
Shopper : Adorama is offering a used version of the Pentax 18-135mm lens. Could you let me know what the condition is of this lens? Thanks you.RALPH Z : I purchased this lens brand new. It arrived in excellant condition and is very compatable with my K-7. No mistake on my purchase. Works Great. Very Satisfied.LARRY N : Seems to me this question needs to be directed to Adorama sales personnel.MARTIN S : I purchased this lens new and returned it within a few weeks. It was never used outdoors and I only took a few dozen shots with it. It wasn't what I was looking for. You could say it is in like new condition.

excellnt

I like the range of this lens along with the weather resistance aspect. This lens along with my 50mm-500mm gives me pretty much all the range I need for my photographic needs.

Great color rendendation

This lens is such a great walk-about lens. The color rendition of this is so pleasing and the contrast wonderful. I've used other systems, but none of my other systems have approached pleasing capability. I also have a third party faster land strong zoom lens usually used for sports, but this one is my main go to lens.

This lens is sharper than I was expecting, excellent color and contrast. A little distortion at the wide end, but easily fixable. A good walkaround lens

It's the Mama Bear of lenses.

That's right, not to big, and not to small. I used the 18-55 kit lens for about ten years on my K-100D. However, after moving up to the K-50, I noticed that my old 18-55 was getting a little stiff on the focus-not to mention noisy. Must have had something to do with falling three feet to the ground on the side of the lens. So I pulled the trigger on the 18-135, and I have been very impressed. Very sharp and the extra reach lets me get superb photos of birds and landscapes. It's also a very good a portrait lens...extremely sharp at 40-90 range. Even though it has the same 3.5-5.6 aperture range, it sure does seem to me that I can shoot at much faster shutter speeds than I could with my old lens. All in all, it really woke up my new K-50. If you're hesitating with this product, get off the fence and buy this fantastic lens.

Good alternate to kit lens

I needed a simple all in one lens with more reach than the standard 18-55 but not as heavy as the 18-200 (which I previously owned and did not like). I use mainly my 35mm and 50mm and while this doesn't compare to those, it's good enough to keep on and enjoy outdoor shots. Indoor I wasn't worried because I can crank up the ISO. Good lens to have in the bag.

Excellent Weather Resistant Lens

I bought this lens to go along with my Pentax K30 for the weather resistant feature. I am loving this lens. I can take the lens out while walking the dog in all weather. I am a "newbie" photographer, but I am interested in tack sharp photos. Despite my beginner status, I have some lovely, sharp looking photos of snow on evergreen trees and my local park. Shout out to Pentax for offering a great product, weather sealed, at a reasonable (for photography hobby anyway) price!

Excellent lens

It's weather sealed, auto-focus is fast and quiet. 18-135 range is fantastic for an all around lens. About the only thing this lens isn't good for is moving subjects in low light. If it was an F/2.8, or faster, it'd be perfect but would also cost WAY more. I am very happy with this lens. This lens is really heavy. It seems to weigh nearly as much as the K5ii.

Nice Little Lens

I had read some negative reviews of this lens, primarily in its optics, but I've found the optics more than good enough - certainly good enough for most of the things I want to do with it. The built-in DC motor makes focusing very quiet, and it's pretty quick on my K-30. It's small and compact, with a nice, solid feel. All in all, pretty close to perfect for a travel lens. It may not have a constant f/2.8 aperture, but no zoom lens with as wide a zoom ratio as this ever will.

Pentax SMCP-DA 18mm - 135mm f/3.5-5.6 AL

I purchased this lens with the Pentax K-30 as a run around camera/lens that I didn't have to worry about on the beach, paddleboarding, etc. Like it a lot, especially the weatherproofing. Easy to understand and use. I chose the white/black model and love the look of it. For sure this combination is not as sharp as what I'm used to with Nikon pro lenses/D3s but I didn't purchase it to use for my business, I wanted something that wasn't heavy and was small enough to fit in my purse at all times. I prefer dslr's to point and shoot and this is a small fun camera to use - video is easy to use too!

Great Lens for overall use

This is great lens. Definitely more bells and whistles than a kit lens and pretty versatile. Do I wish it was a 2.8, sure. but it is decent at 3.5 wide open and I find that slowing the shutter down a bit compensates pretty well. Takes really nice pictures.

Great walk around lens

Great all around lens. Quick focus. Decent range from wide angle to telephoto. Fast enough to freeze action and clear enough for just about any shot.

Good all around lens

This lens is fairly heavy making it a challenge at times to hold still especially with slower shutter speeds. Rarely I got some blurred shots but I suspect it was camera shake and not the lens itself. It is a good lens that truly does the job. I purchased it with my K-5 as an upgrade over the kit lens. It is a good fit.

Great Walk Around Lens

Great all around lens. Size, weight, and focal length coverage are a good compromise when you can only take one lens with you. F-stop is adequate; everyone wants a lower f-stop but then you will be spending more and carrying around a bigger, heavier lens. Auto focus is actually very quick and accurate for a Pentax. Weather sealing makes it worry free on on wet or dusty hikes - it rains here a lot. Lens has a solid feel to it. Great Pentax color. Image quality is not as sharp as lenses that cost twice as much (like a DA* lens); but then they cost twice as much. Image quality is still very good. I have been shooting with it for 6 months; very happy with it.

An Excellent Walk-Around Lens

I really like this lens. For me, it's a perfect everyday walk-around lens. The focal length works great for pretty much everything I use it for (car shows, family gatherings, outdoor scenery). It's lightweight, the auto-focus is fast and quiet, the sharpness and color etc. are quite good for me and it "feels" very well built. It is a little slow (f3.5-5.6) but I knew that when I bought it. Overall a great lens that I'm very happy with.

Good general purpose lens

I wanted a general walk around zoom lens that bridged with focal length overlap at both ends between my wide angle zoom (12-24) and my telephoto zoom (55-300). It fits the bill nicely and would be my first choice as a kit lens rather than the usual 18-55 zoom, which it replaced in my bag. It's a little slow and I wish it had a wider maximum aperture. The auto focus is very quick and very quiet and is not prone to hunting the way some of my other lenses are. I also like the weather resistance. That along with the weather resistance of the body gives me a sense of comfort in inclement weather.
