Sigma 18-300mm f/3.5-6.3 overview

  • 1Description

An all-in-one zoom for APS-C cameras, the 18-300mm f/3.5-6.3 DC MACRO HSM Contemporary Lens from Sigma provides users of Pentax K-mount cameras with an extremely versatile focal length equivalent of 27-450mm. The lens also has a maximum aperture range of f/3.5-6.3 and benefits from the inclusion of one SLD and four FLD elements. Additionally, a Super Multi-Layer coating on the elements results in less flare and improved contrast.

Utilizing a Hyper Sonic Motor for autofocus ensures quick, quiet, and accurate focusing, all the way to the lens' minimum focus distance of just 15". A lens hood is included with the lens and it is compatible with Sigma's USB Dock for installing firmware updates and adjusting focus.

Lens construction with 17 elements in 13 groups
Super Multi-Layer Coating reduces flare and ghosting for higher contrast images
"F" Low Dispersion, or FLD, glass is designed with performance similar to flourite elements with a low refractive index and low dispersion for minimizing chromatic aberration as well as clearer and sharper imagery

    Sigma 18-300mm f/3.5-6.3 reviews

    18-300mm f/3.5-6.3 DC MACRO HSM Contemporary Lens for Pentax K is rated 4.8 out of 5 by 17.
    Rated 5 out of 5 by from Bye Bye Bridge Camera Over the past 6 years, I have been getting progressively more interested in photography. Like many hobbyists, I started out with point and shoots, eventually graduating to long zoom bridge cameras. While I still enjoy them for their convenience and ability to get up close and personal with far away subjects, I have more and more been aware of their limitations in image quality. On the other hand, I don't want to be stuck with a DSLR and a bag of fixed focal length lenses when I am out shooting for fun. After a couple of weeks of practice shots, this lens, attached to a Pentax K-50 body has been the perfect compromise between the versatility of a bridge camera and a the image quality of a DSLR with a fixed focal length or short zoom lens.

    Rated 5 out of 5 by from Outstanding Superzoom I initially had my doubts regarding the performance of this lens. But after several weeks of use, I'm now a believer. I was very impressed with the sharp images, fast focusing, color rendition, and very wide availability of focal lengths in such a nice, compact size lens. My personal recommendation would be to disregard the superzoom naysayers rhetoric, shelve the heavy bag of lenses, and give this versatile, affordable, high quality, lens a try.

    Rated 5 out of 5 by from Great all-in-one lens! Nice lens!! Heavier than expected but the build quality is probably the reason. I was pleasantly surprised with the sharpness of this lens. Seems to be quite sharp across the spectrum. I tried it out on a very recent trip - used the entire range from the 18mm mark all the way to 300mm. On a test-shot of a squirrel in the shade from many yards away at 300mm - no fringing, aberrations or fuzziness. The image blown up to where the squirrel filled the monitor - sharp!! I was pleasantly surprised. I took over 300 images - from cars to waterfalls to squirrels to birds - in sun, shade, and in-between. The only fuzzy pics were my fault. Does it match my 700mm or 14mm primes? No but it is not supposed to. For what it is described as and its intended tasks - it far exceeds any expectations. I would highly recommend this lens as a superb walkaround.

    Rated 4 out of 5 by from Good Bang For A Buck I purchased this lens as a back-up for my Sigma 50-500 lens. While shooting landscapes with with my Sigma 17-70 lens situations arose where a longer focal length was required and picking up my other camera wit the 50 -500 attached was not an option (I shoot mostly wildlife). I captured the image but even at 70mm focal length pixelation took over and i missed the shot. Enter the Sigma 18-300. At the low end the lens offers enough width to shoot landscapes while at the long end it offers the opportunity to switch from landscape to close-up without losing a heartbeat. When the lens arrived I mounted it to my prime camera, a Pentax K3. It was a sunny afternoon when i took the first shots and I was impressed with the initial results. The real test came two days later when i took the lens out mounted on my back-up camera, a Pentax K5II. it was a dreary fall day with poor lighting conditions and some shower activity, a day which will challenge any lens to its limits. Even under these atrocious conditions the lens performed quite well. Out of the box i found the auto-focus somewhat sluggish when compares to my other Sigma lenses. it seemed as if the lens could not make up its mind on which target it should focus. But apparently this can be rectified with the Sigma USB dock. Since i have not had time to experiment with it i am unable to comment on this. The lens is lightweight and compact enough that it will fit in a backpack which allows any photographer to take along his DSLR camera instead of a point-and-shoot camera for better results. Overall I think that the Sigma 18-300 is a good lens for the budget minded photographer who doesn't want to change lenses all the time and wants a good bang for a buck. As for the attached photos: one was shot at the 18mm setting and the other at 190mm, so you be the judge. Overall i wanted to give the lens a 4 1/2 star rating, but the system wouldn't allow me to do so.

    Rated 5 out of 5 by from Sigma 18-300 C is the best travel zoom for my Pentax K3 Quite sharp at 18mm and at the other end 300mm. Thanks to B&H for the added bonus of a close- up lens. A good incentive. Delivery was prompt as promised. I'm a happy customer.

    Rated 5 out of 5 by from Works flawlessly, would buy again. It's my go to lens now the only one I carry. It has replaced 3 other lens.

    Rated 5 out of 5 by from Loving this lens! I wish SIGMA made one 18mm-400mm, now I can move around with less lenses and therefore less weight and more room in my bag for other stuff. This lens is very silent, sharp and the contrast is very good, did have some problems focusing in the dark though with my Pentax k3, could be the camera and not the lens, the macro capability is superb, will get the close focusing lens filter, to get even closer.

    Rated 5 out of 5 by from Great hyperzoom lens This is the first lens I bought for my Pentax K-3 II and I am extremely impressed. The lens quality is solid, and images are sharp across all focal lengths and apertures. The autofocus is slower than the built-in AF motor, but it shouldn't be a problem unless you're taking action shots and don't have it pre-focused. The motor is very quiet, though, which is a huge plus over the built-in AF. The lens is heavy, but this is to be an expected tradeoff for not having to carry and switch out 2+ lenses. Pros: - It's a true hyperzoom - Solid build quality and image quality - Autofocus is quick enough for everyday uses - HSM is very, very quiet - Comes with a lens hood (you'd be surprised that some expensive lenses don't) Cons: - Heavy - Focus ring movement is short, so it is very sensitive to small changes in manual focus - Zoom ring requires a nonlinear force to move through the focal lengths (I'm just being picky here) Overall, I am very satisfied with this lens. I just hope Sigma continues to expand their K-mount lineup since Pentax has such a relatively small selection.
