The Pentax smc Pentax-DA 18-270mm f/3.5-6.3 ED SDM Lens is an all-encompassing zoom lens, featuring a 15x zoom range from a wide 18mm to a long 270mm (equivalent to 27.5-414mm in 35mm format). Benefitting the long reach of this lens, two extra-low dispersion elements have been incorporated into the lens construction to help reduce chromatic aberration and improve overall image clarity. A minimum focus distance of 1.6' across the entire zoom range also makes this lens an effective tool for macro and close-up work.

The SDM autofocus system has also been integrated into the design, which utilizes a supersonic motor for fast, quiet autofocus operation. The lens also features a rounded 7-blade diaphragm for smooth out of focus regions and less susceptibility to highlight streaking.

Wide-to-telephoto zoom lens is equivalent to 27.5-414mm in 35mm format.
Two extra-low dispersion (ED) elements help to reduce chromatic aberration and improve image quality and clarity throughout zoom range.
SDM autofocus system incorporates a supersonic focusing motor for fast, quiet action.

    I used to lug half a dozen lenses with me, until I started using a Tamron 18-250, which I changed for a Pentax 18-250, and since last month, upgraded to the Pentax 18-270.

    One very good move: I managed to change a very good lens for one even better!

    I am an enthusiast, and love travelling, and decided that the best all-rounder is a 18-270 lens, where I am always prepared for whatever surprise I find - a bird far away, requiring the 270mm, or a sunset, demanding 18mm. A close-up, like a flower, or family and friends getting together: whatever your need, it is there for you, without wasting precious time to change a lens, risking to loose the moment or even getting dust on your sensor.

    The perfect traveler's companion!

    The 18-135 mm lens let you move focus while on automatic focus and if you want the off center point of focus you just switch to manual. Its a quick operation that the 18-270mm lens does not have. And will not have because obviously the motor in the body is not suffient to move the 270 mm lens and thus the motor in the 270 mm lens.

    Good all-around travel lens

      Comments about smc Pentax-DA 18-270mm f/3.5-6.3 ED SDM Lens:

      The 18-270 works with well on the K20d and K-r, although I use it mostly on my K3. It is good all-around travel lens. It is good for bird shots, but I find it most useful for close in "macro" type shots for small critters such as butterflies, moths, millipedes, etc. I can stand a good distance away (4 to 6 feet) and still get good sharp images. Sometime it seems a bit soft at very long distances, but I suspect that may be more because of dust/mist/particles in the air. I miss the fact that it's not weather resistant. In inclement weather I have to use my 18-135 lens.

        This lens was purchased to replace a world weary Sigma 18-200mm zoom. A good lens but starting to show its age. Matched to a K5 II, the lens is very quiet and smooth in auto focus mode with a light manual focus ring. Zoom ring is large and easy to use but feels a bit stiff, will probably get easier with use. Test shots so far look good with no significant problems over the zoom range.

            Have used the lens for a couple of month and I am very happy with my purchase. Takes a clearer picture than than the 18-135 lens that came with my K-3. Lens has a solid feel about it as well as a smooth action. Have no hesitation recommending this lens, the joy of not having to constantly switch to my 70-300 lens is worth loosing the distance. Please be aware that I am only a casual photographer and my use of the camera is basic.

            Have only had the lens for a little over two weeks and taken 30+ pics. So far the pictures have been great as expected from a Pentax lens. A little hard getting used to the quiet focus motor when other lenses I have had make some noise, I will learn. I noticed the focus ring has less travel than other lenses, and would be more difficult to focus manually. But since we don't use manual much these days I don't see a real problem. The 18 to 270 mm zoom range is a big feature. Love it!

              It is quite sharp for a lens with that long a zoom range and fulfills my hopes.

                  I have used this product on my K3-II for about 2 weeks and have seen fine results. I plan to use it in traveling in the next six months and will know more then. Thus far, I find it very sharp at all stops, stiff focus (which I personally like because it will not drift) and focuses very quickly and quietly. Overall, I'm very pleased with this purchase and would certainly recommend it to others.

                  I have only had this lens for a couple of weeks, but I am very pleased with it so far. I also have the Pentax DA 18-135, and the 18-270 is definitely an upgrade. It's quiet and seems sharp to me throughout the range that I have used most: I tend to back off from the 270 endpoint a bit. Not a lightweight lens, but you can't heav everything, and I think most people won't find it cumbersome to walk around with. If I ever get a vacation, this will be the lens I take.

                  Comments about smc Pentax-DA 18-270mm f/3.5-6.3 ED SDM Lens:

                  This lens has outperformed both my expectations and many of the on-line reviews. Image quality, flexibility, amazingly quiet autofocus, all came together to satisfy my needs.

                  I firmly believe this great walking-around lens is the perfect complement to my primes that range from 15 to 35, 50, 77, 100 mm. The only downside, perhaps, is the speed that does limit working in subdued lighting. However, the price of a fast lens with such a focal length range would be prohibitive - I can learn to live with it. I love this piece of glass.

                  After a two-week trip to Alaska, in which I was hiking every day and encountering many (inconvenient) situations that required lens changing, I swore that next time, I'd have a superzoom lens on my K-3. This was the obvious choice, as the Pentax and Tamron 18 - 250 lenses are out of production. The lens focuses quickly and quietly, finds focus easily at all focal lengths, and the image quality is better than I was expecting. No, it's not very fast and it's not as sharp as a prime lens. If you need that for every shot, this lens isn't for you. But for if you're headed for a place where changing lenses constantly is going to be inconvenient, this is a good choice. If it was weather-resistant, I'd give it 5 stars.

                      Been using Sigma's 18-250 Macro until this little gem came down in price. In terms of center image quality my DA lens wows across the whole range, but compared to my Sigma, seems a bit softer fully extended. I understand this trade off, and love the extra reach to pull subjects in closer. Thanks to the great B and H deal, I'm extremely satisfied with my new 18-270. Only wished it was available as a WC series.

                        It is exactly what I was looking for, THE zoom! With it I am no more in the need to change lenses and can take only the camera with me in my excursions, very confortable ...and no risk to let the dust enter the camera. This is a perfect lens for traveling and everyday-useage. I love it, as it is versatile, ranging from wide to telephoto, which avoids me changing lenses all the time and getting my precious sensor dirty/dusty. I seriously recommend it to people who love to have their camera at the ready, but do not like to change lenses all the time. I have no issues with focus at all.

                        Wonderful zoom lens!! It has incedible zoom, and the focus ring is much better than others I've used (only matters for manual focusing). If you want to only carry one lens around I highly recommend this one for the gig! I use it for everything from landscapes to close up shots. Great glass for the price. You're very lucky if you get to learn photography on as versatile a lens as this one!
