As a huge fan of ultra-wide-angle lenses, today I will have the opportunity to share an opinion about one of their representative and specifically for Canon EF-S 10-18mm f / 4.5-5.6 IS STM. This lens was released in May 2014 but who knows why i did not find time to check it out. A year later ( May 2015 ) I I had the opportunity to shoot seriously with it on a wonderful trip to the Austrian capital Vienna. For several days, armed with photographic equipment Canon I finally managed to make a bunch of photos and video which after that with pleasure i shared in the pages of PhotoCafe.
Canon EF-S 10-18mm f/4.5-5.6 IS STM
Base class lens – budget and accessible designed for DSLR cameras Canon’s matrix type APS-C (x1.6 Crop factor). Cannot be placed on full frame cameras (35mm. standard). There are structural limitations. To test it I pick the highest class „Crop“ camera – Canon EOS 7D Mk II. I have an affinity for the top cameras and look to take advantage of them whenever possible, and the results reflect well the capabilities of the lens. As mentioned above this is the base class lens. It is aimed at photography enthusiasts that shoot with cameras like 1000D; 100D; 750D; 760D, but i believe professional photographers with cameras from the class of 70D and 7D would not mind using it at all.
|Type Focus||rotating zoom|
|Focal length||10–18 mm.|
|Max. Aperture||F4.5 – F5.6|
|Min. Aperture||F22.0 – F29.0|
|Min. Focus distance||0.22 m.|
I will start with the focal length range from 10 to 18 mm. Most „kit“ lenses for APS-C cameras from low and middle class have a range of 18 to 55 mm. Equivalent to 35 mm standard that allows angular range of about 29 to 80mm lens. That makes the millimeters at the widest part too insufficient for lovers of huge landscapes or shooting in tight spaces. Canon EF-S 10-18mm f / 4.5-5.6 IS STM expand with quite big angular range. Equated to 35 mm standard we already have angular range of 16 to 29 mm lens – the limit of ultra-wide-angle lenses. So If by now you look only thru your “kit“ lens, then glancing through the Canon EF-S 10-18mm f / 4.5-5.6 IS STM positioned at 10mm. the effect will be WOW… at least that’s what I’ve noticed when people try it.
Aperture – The lens is a bit dark I admit. That can be shortcoming in situations of low light (for example inside some cathedral) so you will be forced to use tripod or to compensate with the ISO sensitivity. But the low brightness give two positive things to Canon EF-S 10-18mm f/4.5-5.6 IS STM – first very low price (which excites many users) and second smaller size and weight. My opinion is that the best results you will have at aperture 8. I what found after checking the pictures that were made with it. At f8 I get the maximum sharpness and minimum chromatic aberrations.
Chromatic Aberrations – the lens is basic class. At maximum aperture 4.5 I observe visible chromatic aberration. A bit spherical effect is seen in extreme close-up photos when the lens is most open. The good news is that these problems can be easily corrected even in the camera itself. Look at the menu and you will see where to turn the adjustments, this may lead to delay in shooting a series if accidentally you start wonder why the camera is shooting slower. This applies to those of you that shoot in JPEG. As you know shooting in RAW allow us to use post processing softwares like Adobe Photoshop or Adobe Lightroom so here is good to know that Adobe has developed a profile for Canon EF-S 10-18mm f/4.5-5.6 IS SMT, which when applied cleared almost completely chromatic aberrations, vignetting and the spherical distortion. In addition putting the slider of clarity at 18 or 20 will improve your contrast if shooting macro.
Stabilization – The optical stabilization allows us shooting up to 4 stops under the rules of shooting from handheld camera. Do you remember it? I would add that all this rules depends on how “nervous” you shoot. For me stabilization at 3 stops is good, but some colleagues go for 5 stops that means they can make with Canon EF-S 10-18mm f/4.5-5.6 IS STM image of a half second exposure, and the image will be crystal clear and sharp. And now a little advice…stabilization is designed to remove some of the random twitches but it will not replace your tripod in cases that you will have to shoot below 1/15 of a second.
Focus – Canon EF-S 10-18mm f/4.5-5.6 IS STM as its name suggests is from the series lenses with a stepper motor (STM). Canon created this type of motors to meet the increased shooting of video with their DSLR cameras. That type SMT lenses offer extremely smooth and silent focusing unlike the older motors that are integrated into the lenses from the older generation. Almost reaching the speed of Ultrasonic motors and they are equally precise. With ultra-wide-angle lens like Canon EF-S 10-18mm f/4.5-5.6 IS STM is really hard to feel the speed of focusing because the focus area is quite small and you get the impression that almost always everything is in focus. In that lens we have a lack of scale that calculate the distance from your camera to the object that we shoot, but that is extra which is reserved for higher class lenses.
Quality of production – Canon EF-S 10-18mm f/4.5-5.6 IS STM is made of polycarbonate plastic, even the bayonet, this material is robust and reliable, proven in quite cameras of any brand. Maybe someone will ask „why not a metal bayonet?“ Lens is light enough to be held by a plastic mount, which further lightens it. Bracelet of the wide zoom is equally good for use in summer and in winter with gloves. Bracelet of the focus is much smaller – very common in lens of this class. Anyway manual focus probably you will almost not need and use. You may find on the lens switches for stabilization and focus.
Hood type is tulip, the front element dose not rotate which allowing normal use of polarizing filter. It is recommended the use of filters size 67mm, especially the polarizers type should be “slim” – thin because its much likely to enter in the frame around the edges if the zoom is at 10mm. For dessert I will show you some pictures that I take with that lens from Austria. Looking my pictures again I am convinced that most of the time I shoot at 10mm zoom and just searching for the right position and view. And all that is just to present in to my image some different and powerful story that I want to tell. All this photos had a minor retouch like profile correction, remove chromatic aberration and some contrast. But to be honest I hardly notice any chromatic aberrations in the images. And yes, to shoot indoor I had to go for higher ISO but Canon Eos 7D Mk II is pretty good at quite high ISO, so no big trouble for me at all. The lens is compact and that allowed me to travel with my smaller bag, which is generally design for mirrorless system. In the end of the day Canon EF-S 10-18mm f/4.5-5.6 IS STM with its small size and price fully compensate any optical imperfections.
