I didnt expect to like this little lens. After having used the olympus, sony, panasonic, fuji pancake (the pana and fuji are almost as good but I really hate the a: lack of real MF and b: the irritating powerzoom). This came as a real surprise. The IQ is very good for what this is.

Canon did it again; Very small and light; Very inexpensive; Surprisingly good image quality; Decent zoom and manual focus; On the newest M50 high speed AF; For the price,size and IQ a steal

Only average built quality; Only 3.5-6.3

Using this lens on the M6, the corner sharpness is terrible. I sent it in for repair and that made no difference. You need to stop down to f11 to sharpen the corners. This is an embarassement of a lens for Canon. Other three EF-M lenses that I own are all much much better.

Lens fits camera and works great. I thought it would be heavier but it's light weight due to the material it's made of.

I got this lens because the 18-55 was a bit too long. I've since compared it (pixel peeping) at centre and corners and it is excellent. I now use it as my carry-about lens all the time with my M3. It's small and light and very easy to use.

Consistent Output; Easily Interchangeable; Lightweight; Sharp Focus

Don't know as it is a Christmas present

Compared to the standard kit lens with other EOS DSLRs this is a great kit lens. My copy is extremely sharp and fast and can deal with all manner of lighting. It's discreet for street photography and lightweight for travel.

Announced in October 2015 to complement the EOS M10 camera (which we didn't review), the EF-M 15–45mm f/3.5–6.3 IS STM lens is offered as one of the standard kit lenses with the new EOS M5 camera .

This lens is amazingly compact, not much longer than the EF-M 22mm prime. The manual retraction feature is easy to use. The quality heft and feel are what you're expect from Canon. Auto focus with the M3 is very quick and accurate. Good color, tack sharp front to back @ f/22.

Conclusions The Canon EF-M 15-45mm f/3.5-6.3 IS STM is a pretty typical example of a starter zoom lens. It doesn't offer the build quality or high-end optics of a premium zoom. Instead it makes compromises in order to manage a small size and a cost that allows it to be bundled with a camera body.

Compact; Crisp center; Wider coverage than other starter lenses; Optical stabilization

Narrow aperture; Noticeable distortion; Dim corners at 15mm; Soft edges; Plastic lens mount; Doesn't include lens hood

As of the time of this review, Canon's mirrorless system is solely targeting the budget market and despite a less then attractive overall system, they seem to be surprisingly successful with this strategy ... if we can believe their marketeers (...).
