Canon announced EF-S 10-18mm IS STM Ultra-wide angle lens for APS-C cameras

May 13, 2014

Canon has announced the EF-S 10-18mm F4.5-5.6 IS STM lens, an affordable ultra wide-angle zoom lens for Canon APS-C bodies. The lens is equivalent to 16-29mm when mounted on Canon APS-C cameras, like on the Rebel SL1 for example.

The estimated price for this lens is $299.99. This means that it’s cheaper than the Canon EF-S 10-22mm F3.5-4.5 USM lens which costs around $600 as of the time of writing. Furthermore, we’ve already some disappointed voices regarding the specs in comparison to 3rd party offering. For example, for around $150 more you can get the Tokina 11-16mm f/2.8. So for a bit more (might not be a ‘bit’ for some), you get, according to some lens review websites, one of the best ultra-wide zoom lenses for cropped-sensor DSLRs. The lens has little distortions, it’s very sharp, has great build quality, but does suffer from CA and slight vingetting at the widest angle and at f/2.8 aperture according to website.

If you search for an affordable ultra-wide angle zoom lens, and you don’t mind the lens being a bit slow, I think that you love this new lens.

I can tell you from my own experience, that ulra wide-angle lenses open up a whole new world of creative photographic possibilities for photographers. I’m not just talking about cityscape, street, landscape or interior shooting, but things that somewhat looked a bit boring on a normal focal length lens, suddenly get a new perspective that catches the eyes of the viewer. No doubt that regardless of the cons and pros that this lens has, it’s great to have another ultra-wide angle lens in the EF-S lens’ lineup.

There are also voices from Nikon DSLR owners that wished that Nikon had followed the same and release it’s own affordable ultra-wide angle lens, instead of offering mainly professional quality lenses at a much high price. Nikon is well known for its superb UWA lenses, which is one reason why some outdoor photographers opt for Nikon bodies, to enjoy these magnificent lenses. In fact, Nikon might release its own budget-friendly UWA lens after Canon released its version.

I’m pretty sure that for many people, there is little to complain about. If you want a faster and high-performing lens, you can always buy one of Canon’s fine UWA lenses, like the Canon new EF 16-35mm F4L lens that was announced at the same day as the 10-18mm. You have lots of lenses to choose from, especially if you are shooting with an APS-C body.

Canon EF-S 10-18mm specs

Let’s take a look at the lens specs:

  • lens construction: 14 elements in 11 groups
  • 8 diaphragm blades for smooth Bokeh
  • Minimum aperture: 22-29
  • 0.22 m closest focusing distance
  • 0.15x (at 18mm) maximum magnification
  • 4-stop image stabilization
  • STM AF actuator
  • 67mm filter diameter
  • dimensions: 74.6 (diameter) x 72.0 mm (length)
  • Weight: 240 g

  • STM (Stepping Motor technology) for smooth and near-silent focusing, especially designed for video shooting
  • Aspherical and UD lens elements ┬áto minimize distortions and chromatic aberrations that can reduce the image quality
  • Dedicated manual focus ring


The main question that still remains is how well this lens performs. If it does perform well in lab test reviews, I think that Canon might have a winner here, and I’m sure that it will sale like cupcakes. You can buy the most sophisticated camera body, but the lens has a direct impact image composition definition and artistic style, and I highly recommend giving yourself a chance to buy an ultra-wide angle lens, or at least rent one, and see what you can come up with.
