What Canon has managed to produce in the EOS 100D is pretty special - a very small body that retains the same DSLR stylings of its larger siblings, and, more importantly, produces impressive image quality. That's quite a feat.
However, the problem remains that although the camera itself is small, the overall system is not. By the time you attach the 18-55mm kit lens, it's not too much smaller than other, cheaper, cameras in Canon's range. Furthermore, if you're intending to use several lenses, you will still need a pretty large kit bag to pack it all in.
It's worth looking at the 40mm pancake lens as an accompaniment to the Canon 100D, since its incredibly small size makes it a reasonable combo for street shooting - albeit with a longer (equivalent) focal length than we'd usually recommend for such work.
It's also arguable that the intended consumer of this camera won't stray too much further than the light kit lens, which does keep the weight down significantly.
Speaking of the kit lens, the new 18-55mm STM lens is a very good performer. If you don't already have any lenses, it's well worth buying the standard kit box, rather than the body-only option. It's a great lens to get you started with until such time that you decide you want to expand your collection.
Images from the Canon EOS 100D are impressive, with lots of detail and bright, punchy colours. Although it doesn't help with size reduction, compatibility with Canon's incredibly extensive lens range does make this a more flexible overall system than the compact system camera it's trying to take on.
Despite the reduction in size, the layout and usability of the Canon EOS 100D is still very good, with buttons arranged so that they're easy to reach and the touchscreen complementary to operability, rather than a necessity.
That touchscreen really comes in handy when zooming into images during playback and accessing different functions on the quick menu.
Perhaps our biggest bugbear with this camera is the hyperbole which is associated with being the world's smallest and lightest DSLR. Does that really mean anything when lenses are still big and heavy?
Aside from that, there are a few other niggles, such as only being able to use digital filters in Live View, or indeed the sluggish performance of AF in Live View.
It's hard to know what to say about the Canon 100D. Canon has once again produced an incredibly capable DSLR, which produces excellent images.
The miniaturisation element is fun, and a nifty feat of engineering, but there's still no way that a camera and system such as this can compete with the likes of the Micro Four Thirds system in terms of weight and size.
That said, if you're already a Canon owner looking for something small to add to your collection, this could be a good second shooter.
