The best way to sum up Canon EOS-M (with 22mm lens) is this – It’s a poor man’s RX1. Of course it will not match RX1’s combo of full-frame sensor with a Zeiss prime but it comes awfully close. And all for a paltry sum of $300 which is what it was selling for as of November 2014.
I have read lots of reviews and examined hundreds of image samples from all kinds of cameras, including the aforementioned RX1. And I can say without any hesitation that this tiny 22mm f/2 lens has ridiculous amounts of resolving power. It’s up there with the best of them. In fact, it’s being limited by the relatively “low-res” sensor. Here is an example.
You can actually read those letters and read them comfortably! Notice how each letter is still distinct even at this tiny size. This would have turned into a blurry mess on a lesser lens. That is some serious resolving power. If this does not make your hair stand up, you are either dead or a medium-format user 🙂
I can only imagine what this lens could do on a higher-res sensor. Here is hoping to a 36MP M3.
