First Impression Of The Canon 10-18 mm Camera Lens

With the EF-S 10-18mm f / 4.5-5.6 IS STM, Canon launches another, more advanced ultra-wide-angle lens for cameras with APS-C image sensor on the market. It replaces the EF-S 10-22mm and is the counterpart to the EF 16-35mm f / 4 L IS USM for the full format. The image-stabilized ultra wide-angle lens arouses a great deal of interest among amateur photographers.


  • Cheap ultra wide-angle lens with a focal length range of 10 – 18mm.
  • Smooth, quiet STM focus during video recording with compatible cameras.
  • Dynamic image stabilizer.
  • Fast automatic focus
  • Very low weight with only 240g
  • Minimum focusing distance of 0.22 m.

Handling And Processing

Within our lens test , we always attach great importance to the handling and processing of the respective camera lenses. Anyone who has had the EF-S 18-55mm f / 3.5-5.6 kit lens in their possession before, or even been able to call it their own, will find similarities in terms of feel and build quality with this Canon lens . For everyone else, the EF-S 10-18mm is equipped with a plastic bayonet and 67mm diameter filter thread. It also has two switches to enable and disable the image stabilizer and autofocus . Furthermore, the camera lens works properly, however, and is with its just 240g a real lightweight . It is the perfect complement to the Canon EF-S 18-135mm or EF-S 18-55mm and with its focal length provides a seamless entry into architecture or landscape photography.

Autofocus & Image Stabilizer

Thanks to “Stepper Motor Technology” (STM), autofocus is used to being fast, accurate and almost inaudible, even though autofocus is generally relatively low due to the maximum aperture of 4.5 and the short focal length. The image stabilizer (IS) is not much different than the autofocus. With a focal length of less than 20mm you can still produce useful photos despite longer exposure times , regardless of whether the IS is turned on or not. With this camera lens, therefore, the benefit of the image stabilizer is not in the photo but rather in the videography .

Picture Quality & Sharpness

The Canon EF-S 10-18mm IS STM is not a shrew miracle. If you are looking for an angle lens that is sharp to the corners and loses almost no contrast in it, you have to put two price categories on it . This should not mean that the Canon 10-18mm is not a good lens. In the image center, it delivers decent results and loses little edge to the edges. The chromatic aberrations, due to the very difficult focal length, fortunately keep within limits. In the outermost corners, although slight color fringes can be seen, but by no means disturbing.

Here is a spontaneous picture with the EF-S 10-18 mm STM lens. This image is completely unprocessed except for the inserted image section. The sharpness of this lens does not need to hide.

The lens also shows a good side in the vignetting. A shading on the edge is on the test images made by us to recognize, on the other hand, anyone who bothers the effect with any image editing program easily correct.

Bokeh Of The Canon Lens

The Bokeh is relatively unimportant in an ultra wide-angle lens , since such a lens rather for architectural and landscape shots with very high depth of field uses. Because of this fact, we add another snapshot instead of a bokeh shot.

This image is also unprocessed except for the image details. The picture was taken with 10mm focal length . Good to see is the distortion on the left edge. We have made this clear with a cut-out of the lamp. The wall next to the lamp looks a bit crooked. This is still relatively normal with such a short focal length. In addition, the edge is a bit “mushy”. In the center, however, the lens is sharper, as you can see in the right part of the image well. In addition, there is almost no distortion to recognize.

The Canon EF-S 10-18mm 4.5-5.6 IS STM is a true alternative to expensive Canon landscape lenses , which also offers a near-unbeatable value for money. The 18mm focal length at the long end also provides a seamless transition to EF-S 18-55mm or EF-S 18-135mm IS STM kit lenses. Despite the very short focal length, it shows only minor glitches and can be recommended without hesitation, as long as it is not intended for professional use. An alternative for the APS-C image sensor is the older Canon EF-S 10-22mm 1: 3.5-4.5 USM, which comes a little light intensity and with 4mm more focal length therefore. The big disadvantage of the older Canon lens, however, is the lack of image stabilization .
