Sigma 886101 18-300mm F3.5-6.3 DC Macro OS HSM Lens for Canon

Product Information

I bought this to replace my wonderful Sigma 18-250 (which my talented 19 -year old granddaughter got to go with the K5 I passed on to her). I use a K5ii, Lightroom, PS Elements and Topaz Clarity, and the LR Lens Correction set and Detail sharpening set put the 18-250 on par with much more expensive brands, and the same is true for the 18-300. The processing software isn't essential to a great result, but it provides good optimization for an already fine lens. Thanks to the optical stabilisation, sharp hand-held images are possible around half the time at shutter speeds as low as 1/40sec at 300mm, which is roughly four stops slower than the usual rule of thumb would dictate is possible. There's noticeable improvement at 200mm. At f/6.3, the lens scores 1,873 lines. If you're paying attention it won't be a surprise that the edges are not good, though, showing just 1,127 lines. Stopping down to f/8 (2,021 lines) and f/11 (2,050 lines) goes a long way to sharpen the center and midparts of the frame, but you'll still be left with 1,222 lines and 1,482 lines (respectively) at the periphery. The color rendition from this lens is very standard for Sigma, which means that it’s top notch. There is no where as high a contrast level as you’d see with the Art series, but instead it is a bit more muted. Despite the muted colors, it isn’t at all horrible and a bit of a saturation boost in Adobe Lightroom will solve any problems. Color Fringing

Both are about the same size and easy to carry. A few comments are that the K5ii and 18-300 seem a bit heavy, but I remind those folks that often that's all I need to carry. Die Aufnahmen, die ich für diese Rezension aufgenommen habe, zeige ich unter stefansenf.de/?p=4268 . Sie stehen beispielhaft für das, was das Objektiv können soll. Den Familienalltag bestreiten. Ausflüge. Urlaub. Schwarzbrot, sozusagen. it’s my first Sigma lens, so I found the "wrong" zoom rotation direction to be rather disturbing, you maybe get used to if you use the lens often, but if you continue swapping lens between Pentax and Sigma you will further continue enforcing wear on your mount by accidentally driving in the wrong direction;Chromatic aberration is the lens' inability to focus on the sensor or film all colours of visible light at the same point. Severe chromatic aberration gives a noticeable fringing or a halo effect around sharp edges within the picture. It can be cured in software. Die ersten Probeaufnahmen Blumen, Insekten, Landschaft waren vielversprechend, ein bisschen Erfahrung braucht es nun noch, um sicher die günstigsten Einstellungen wählen zu können.

Nun ja, auch dieser Punkt geht an das Tamron, das Sigma rutscht sehr schnell heraus, wenn man das Objektiv nach unten hält. Beim Tamron passiert dies zwar auch, aber wesentlich langsamer und weniger. Da muss man dann schon drauf achten, möchte man einen speziellen Bildausschnitt/eine Brennweite dauerhaft eingestellt haben. The build quality of the Sigma 18-300mm f/3.5-6.3 DC MACRO OS HSM Contemporary lens is pretty well built. It isn’t like the Sports optics and only a smidge below the Art lineup in terms of build quality. For the typical APS-C DSLR user, you’ll have nothing to complain about with the build of this lens except that the lens cap should have been better designed. If the lens hood is on, it can be tough to take the lens cap off. Zoom.nl: Deze Sigma zet gezien de adviesprijs goede resultaten neer, aldus de reviewer van Zoom. “In de groothoekstand was de scherpte in dit prijssegment uitstekend, datzelfde geldt voor het middengebied van het optisch bereik. In het telebereik liep de scherpte wat terug, maar scoorde het objectief nog altijd goed.” Krijgt van Zoom het cijfer 7.4. Natürlich muss einem klar sein, dass eine solche Lösung immer einen Kompromiss (hinsichtlich der Bildqualität) darstellt, welchen vermutlich „Hobby-Fotografen“ eher bereit sind einzugehen als Fortgeschrittene oder Profis. Hier muss man für sich entscheiden, ob einem die Bequemlichkeit (= Immer-Drauf-Objektiv) oder die bestmögliche Bildqualität (= separate Objektive je nach Einsatzsituation) wichtiger sind. Opinione: Obiettivo decisamente versatile, comodo in viaggio e in tutte le occasioni dove è necessario razionalizzare il numero di ottiche da portarsi appresso.A petal-shaped hood is supplied as standard with the lens, which does a good job of protecting the lens from extraneous light that may cause unwanted flare and loss of contrast. During testing there were no issues with flare and contrast holds up well, even when shooting into the light.

The macro designation means that it has a relatively close minimum focusing distance and is capable of producing macro images (1.0x or 1.1x magnification).The pictures below illustrate the focal length range from wide to telephoto (on Nikon DX format, 1.5x). This lens has a 16.6x zoom ratio covering focal lengths from wide to telephoto and it also offers a 1:3 (0.33x) macro ratio. The lens has a built-in HSM autofocus motor. The lengthy title for the Sigma 18-300mm is simply a road map so that you know exactly what the lens brings to the table. In terms of lens controls, this lens has a switch for MF/AF focusing modes and optical stabilization. These are both guaranteed to be on for most users. Falloff of illumination towards the corners is typical of a lens of this type. At 18mm the corners are 1.91 stops darker than the image centre and at 300mm the corners are 1.48 stops darker. Visually uniform illumination is achieved with the lens stopped down by just over a stop from maximum aperture throughout the zoom range.

Ich habe das Sigma 18-300 aus der Contemporary-Serie erworben, um es als „Immer-drauf-Objektiv“ an meiner Canon EOS 1300D zu nutzen. Parallel hatte ich zum Vergleichen das Sigma 18-250 [ Sigma 18-250 mm F3,5-6,3 DC Macro OS HSM Objektiv (62 mm Filtergewinde, für Canon Objektivbajonett) ]erworben. The the Sigma 18-300mm f/3.5-6.3 DC MACRO OS HSM Contemporary is one that is characterized by a rather spiffy looking exterior. Much of it is dominated by the zoom ring, but the parts that aren’t have a bit of extra class to them without looking pretentious. In alcuni scatti l'aberrazione cromatica è decisamente evidente, Lightroom aiuta ma non elimina totalmente l'effetto.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. The lens will be available in Sigma, Nikon, Canon, Pentax and Sony mounts; Pentax and Sony mounts will not offer OS.
