![]() ![]() Macro UseĪfter-all, this lens bears the designation of a macro lens so let’s talk a little about how it truly performs as such. Fortunately, it was easily removed with one click using Lightroom, so all is not lost. However, it had a significant amount of chromatic aberration which was quite apparent, and worsened towards the edges of the frame. Colors came through true to life, and quite crisp across all focal lengths. This is a scene shot at the shortest focal length of 18mm and at f/6.3.įor comparison, here are two images shot from the previous vantage point, after zooming to 300mm (shot at f/6.3).Ĭolor rendition is very good with the Sigma 18-300mm. Maximum sharpness seemed to be achieved between f/8 and f/16. Each of these images were shot at 18mm, at apertures ranging from f/3.5 to f/22. Test images showed that sharpness is acceptable/good across all apertures for a lens in this range, and likewise with contrast. Lens Hood Indicators: In addition to the rubberized ring, the lens hood also has mounting markings to help mount the hood on the go or in low light.It makes lining up the lens much easier, and is longer lasting. Sigma has chosen to use a small white bead embedded into the lens body instead of merely paint. Raised mounting indicators: Attaching your lens to your camera can be difficult in low light or if you’re in a hurry.Zoom-Lock: The zoom-lock switch is a great feature for any zoom lens in my opinion, by preventing gravity from gradually extending the lens while carrying your camera on a strap.Here are a few small points that stand out about the Sigma 18-300mm. Speaking of details: The effort (or lack thereof) a manufacturer puts towards the little things is of great importance. It’s a small detail but worth mentioning. Sigma also placed a small rubberized ring at the base of the hood which really helps in the on/off application. Included in the box is quality petal-type lens hood, which fits the lens perfectly and mounts in reverse for storage. The overall body of the lens is finished with a very understated yet attractive matte black appearance, in case you love form as much as function. It became virtually unnoticeable at longer focal lengths, so it remained off for the majority of the test images. Autofocusing performed very well and was quite fast using my Canon 7D, but the image stabilization was not the best. Some telephoto lenses of this type arrive a little too tight and require some use before the zoom ring operates easily, but the Sigma 18-300mm was just right out of the box. Everything is exceptionally tight and smooth. ![]() Both the focus and zoom rings are rubberized, and provide a suitable grip for cold or damp fingers. The lens felt very solid but in no way overly heavy. First handling of the lens proved to be immediately impressive. The optics were all clean and free of smudges and dust. The lens arrived well packaged from Sigma. This lens is designed to be mounted only to APS-c(cropped) sensor cameras.
