Image quality, vignetting, flare and distortion test results along with specs, measurements and standard product images have been added to the Canon EF-M 55-200mm f/4.5-6.3 IS STM Lens Review page.
Canon EF-M lenses are compatible only with the compact Canon EOS M MILCs (Mirrorless Interchangeable Lens Cameras). The 55-200 IS STM is the telephoto lens option in the "M" lineup (though others are available via the EF to EF-M adapter). This lens has good image quality with a very small size and light weight.
Please note: Like the T5i, T4i and 70D, the EOS M has image sharpness dialed up (by Canon) in-camera. Even though the EF-M lens test results shown use our standard sharpness setting of "1", you will see the sharpness difference when comparing against EOS 60D-based lens test results. The increased sharpness comes directly at the expense of increased high ISO noise and can be adjusted to taste. Still, this is a good lens.
Special thanks to John S for loaning us this lens!
