Photographer Christopher Frost published this interesting review of the small EF-M 15-45mm f/3.5-6.3 IS STM lens for Canon mirrorless cameras.
A day after Canon announced its new EOS M5 advanced mirrorless camera, making this lens even more relevant now than before. We are currently on our way to Photokina where we will have time to bring to you a hands on with the EOS M5 (and possibly the EF-M 15-45mm f/3.5-6.3 IS STM as well).
The lens has a plastic lens mount and although it is very small and light the aperture is not amazing (f/6.3 at 45mm so you will not get too much light at the telephoto end). The focus is electronic but seems to do well is general.
The AF is silent quick and accurate and the image stabilisation seems to work well. Wide open the center is sharp and the corners pretty soft. The corners improve up to f/11 to a reasonable level (especially at 45mm). Keep in mind that this isn’t a very good lens for close ups (not to mention macros).
The Canon EF-M 15-45mm f/3.5-6.3 IS STM sells for just under $300.
