The Canon EF-M 55-200mm f/4.5-6.3 IS STM is a series telephoto lens of the Serie M produced since 2014 from the Japanese house. Suitable only for APSC format devices. Focus is automatic and takes place via AF non -ultrasound engine which is quite precise and quiet. Image stabilization is present and discreetly effective. The lens is low -end and this is also seen from the quality of the images, not very bright and which transmit little. Obvious defects such as aberrations or distortions are not present, despite the fact that it remains an economic lens and without too many pretensions. The M series of the Canon is made with more plastic materials than the upper and therefore less resistant and less lasting series over time. The minimum focus distance is equivalent to one meter, enough to be used in contexts such as urban, street or landscape. The speaker is available but available separately. The Canon EF-M 55-200mm f/4.5-6.3 IS STM is an ideal lens to photographers looking for a simple lens with a good focal length but without exceeding in quality, a small investment for an economic product that will be able to repay in any case expenditure made. Not recommended for professionals, other superior quality lenses are available with just -upper investments, moreover it is not possible to mount them on FF which makes it not very attractive to this category of photographers.
