Pentax 18-270mm f/3.5-6.3 overview

  • 1Description

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.
Specifically designed for use with Pentax K-mount DLSR cameras.

    Pentax 18-270mm f/3.5-6.3 reviews

    smc Pentax-DA 18-270mm f/3.5-6.3 ED SDM Lens is rated 4.6 out of 5 by 40.
    Rated 5 out of 5 by from Perfect Travel mate 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!

    Rated 4 out of 5 by from Pentax-DA 18-270mm f/3.5-6.3 All in one nice lens especially when want to travel light only with one lens. It is slightly soft on wide aperture and from start getting sharp from f/6.3 then f/8 to f/11 is very sharp, very nice built in quality and good IQ when comparing with same range 3rd party lenses. I used this lens quite a lot and observed that it getting better and better day by day which means that need time to understand the specification of this lens in order to get the full positive result. I would have been 5 stars if focus was slightly fast in low light condition.

    Rated 4 out of 5 by from Good all-around travel 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.

    Rated 5 out of 5 by from Great Lens! I have used Tamron 18-200, Sigma 18-250 and then just came across to Pentax 18-270 and I must say that it was not bad to make up my mind and buy this lens. This lens is amazing all in one lens, I used it on my vacation trip and was extremely happy with the performance. Fast Auto focus though a bit struggle in low light but still much better than others, I don't think its a negative point since we all know that we have to compromise somehow for all kinds of zoom lenses. The sweet point of this lens start from 6.3 then 8 to 11 like a razor sharp.....

    Rated 5 out of 5 by from Great Lens, I love It! everything I hoped for 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.

    Rated 5 out of 5 by from This lens is not a bust. I wrote a review on this lens saying the auto-focus is a bust. Gave it 2 stars. Not so. Operator error caused the problem. This lens is a good lens My Bad.

    Rated 5 out of 5 by from Good walk around lens Got this lens to replace a Tamron 18-200mm zoom. The Tamron lens was working well, but I liked the extende zoom to 270mm and the SDM focusing as I shoot a lot of action shots. Used it last weekend to cover multiple events at our community Independence Day activities for the local newspaper. Took photos of the model airplane show, boat parade, swimming pool events, sky divers, and fireworks, all with good results. Shot over 500 photos. Would recommend this highly.

    Rated 4 out of 5 by from Excellent for its purpose 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.
