It is an all-in-one zoom lens featuring a sleek design and characterized by versatility and compactness. As it forms a part of the Contemporary-series lens, it prioritizes ease of use with impeccable performance. This makes it an ideal lens which is well-suited for all sort of photography applications.

Sigma 18-300mm lens review

Some of its notable features include an optical design containing a series of aspherical and low dispersion elements that help minimize significantly chromatic and spherical aberrations all through the zoom range. It also features a Super Multi-Layer Coating, which controls lens flare and reduces ghosting.

Additionally, it is also adept at close-up shooting s it employs a 1:3 maximum magnification along with a 1.3′ minimum focusing distance. To balance these optical capabilities, this contemporary lens is also characterized by a Hyper Sonic Motor to make it fast and precise when focusing.

This not only enhances performance but also gives it the ability for full-time manual focus control. It also sports an Optical Stabilizer, which results in sharp imagery as it minimizes the appearance of camera shake. Moreover, it has a small build, which contributes to both easier handling and convenient carrying.

Let us look at all the above-stated features in detail to understand what makes this Sigma 18-300mm F3.5-6.3 DC Macro OS HSM so special:

Product overview:

First of all, this zoom is in an all-in-one lens that is perfectly designed for APS-C-format Canon EF-mount cameras. It offers a 28.8-480mm equivalent focal length range and is ideal for close-up shooting as it provides 1:3 maximum magnification together with a minimum focusing distance of 1.3′. This makes it well suited for working with nearby subjects.

Coming on to optics, this lens employs not only One Special Low Dispersion (SLD) but also has Four F Low Dispersion (FLD) elements in its optical design to minimize both color fringing and chromatic aberrations. This results in enhancement of clarity as well as color accuracy. For further improvements in results, it has three aspherical elements that limit distortion and prevent spherical aberrations.

This benefits both accurate rendering and overall sharpness. It is also all individual elements coated with Super Multi-Layer Coating to reduce ghosting and lens flare. This leads to even more enhancement, especially in backlit conditions, as results become contrast-rich and color-neutral.

Good performance

Next is the performance, which is also optimal. Sigma has been successful yet again in giving both top-notch optics and on point functionality. This has been possible due to the integrated HSM (Hyper Sonic Motor) complemented by a rear focus system that contributed to fast and quiet, and precise autofocus.

The performance is further enhanced by an optimized AF algorithm that smoothens the focus. Another advantage of the HSM is that it also provides full-time manual focus control to the user, which can be gained by merely rotating the focus ring.

This lens is also perfect in terms of lens controls. It has a switch for MF/AF focusing modes that are easy to use. It features an optical stabilization system, which reduces the camera shake’s appearance so that sharper imagery can be achieved when conducting handheld shooting. Moreover, this lens also extends out from the original collapsed position. Then it also has Macro focusing markings on enabling very close up focusing.

It also employs a Zoom lock switch, which prevents both unwanted and accidental zoom adjustment. It is also compatible with the Sigma USB Dock so that different lens characteristics can be tuned and even for updating of firmware.

The exterior of the Sigma 18-300mm f/3.5-6.3 DC MACRO OS HSM lens is also top-notch. It is characterized by a somewhat sturdy outlook, which is mostly dominated by the zoom ring.

72mm filter thread

The rest of the prospects is very classy. A pretty small lens hood protects its front element, and it also has a 72mm filter thread, which works quite well with close up filters. Coming on to build quality, this Sigma is pretty well established.

You will find nothing to complain about in both its quality and design. Both are top-notch as it has been crafted with top-notch Thermally Stable Composite (TSC) material, and the construction is done to perfection. Except for the cap, everything not only looks perfect but also works perfectly. The material also makes it capable of being used in wide temperature variations and also adds greater precision.

Then it also features a brass bayonet, which enhances mounting accuracy and rigidity. Then what makes this lens stand out is its compactness. It is the zoom locking function that collapses the glass, making it easier to carry.

When talking about sharpness, you might find the Sigma 18-300mm lens very basic initially, but you had been incredibly wrong. This lens exhibits sharpness exactly like all high-end lenses when using artificial lighting.

Sharp lens

The sharpness is also on point, even when working in natural light. The images that it delivers are beautiful, even though the bokeh is not very surprising.

Yeah, like all Sigma lenses, both the color rendition and bokeh are pretty much standard in this lens. This means that it is not top-notch and not as high a contrast level as found in the Art series.

Instead, the rendition is more muted, which is lacking. But even muted colors are not a problem as a bit of saturation boost in Adobe Lightroom can resolve it. This means the final results don’t look bad at all, so it’s not such a big deal.

All in all, with perfect sharpness, focusing, handling, and classy built, this lens is a significant player in its market. It is topping the charts, and photographers who like to experiment with zoom prefer it over all others. Like all times, Sigma has succeeded in fulfilling its user’s requirements and creating a lens that performs over the expectations!
