Canon EOS M Review

Canon EOS M

This is an in-depth review of the Canon EOS M camera that came out on July 23, 2012, the first mirrorless interchangeable-lens camera from Canon. Along with the EOS M, Canon also announced the first two lenses for the new “EF-M” mount: Canon EF-M 18-55mm f/3.5-5.6 IS STM and Canon EF-M 22mm f/2 STM. Among major camera manufacturers, Canon was the last to enter the mirrorless market. Aside from Panasonic and Olympus sharing the same Micro Four Thirds sensor and Nikon going with a smaller “CX” sensor, all other manufacturers chose large APS-C sized sensors (Samsung, Sony, Fuji and Pentax), each with its own proprietary lens mount. With the introduction of the EOS M system, Canon has officially joined the APS-C club. Instead of developing a new sensor format, Canon chose to reuse the same 18 MP sensor from the EOS Rebel 650D / T4i DSLR camera. Canon also released an EF-M to EF / EF-S adapter for mounting existing and future DSLR lenses on the EOS M, with full compatibility with all lens functions such as autofocus and image stabilization. In this review, I will go over the features and capabilities of the camera and compare it to other mirrorless options, including Nikon 1, Sony NEX series and Olympus OM-D E-M5.

Battle of the Mirrorless – Part 1 (Dynamic Range)

Mirrorless Cameras and Lenses

As promised, I have performed some additional dynamic range tests on the mirrorless cameras I am testing (Nikon 1 J2, Canon EOS-M, Sony NEX-F3, Sony NEX-5R, Sony NEX-6, Sony NEX-7 and Olympus OM-D EM-5) and I have the data ready for your viewing pleasure. As expected, the Sony APS-C sensors performed the best, with the Sony NEX-5R and NEX-6 leading the game (although other NEX series are extremely close) followed by the Olympus OM-D EM-5, then Canon EOS M and then finally the Nikon 1 J2. Here is a comparison chart that shows performance of the various mirrorless cameras:

Battle of the Mirrorless – Part 1 (Low Light Performance)

Mirrorless Cameras and Lenses

I have spent a considerable amount of time working with 7 different mirrorless cameras from Sony, Canon, Nikon and Olympus. I apologize for not being able to provide periodic updates on these cameras. I have come up with new ways to measure digital camera sensor performance, so it took me a long time to do it in a way that I believe will be more accurate and objective compared to my previous methods. Not only will you be seeing crops of sensor performance in a controlled environment, but I will also provide some numbers to quantify performance in colors and dynamic range. As I have already mentioned before, I will be measuring dynamic range myself going forward without having to rely on other websites for the data. It will be interesting to see how my data compares to other sites like DxOMark. I am not planning to do anything super intensive and I bet my measurements will not be without issues and errors, but I believe it is something worth trying. Hopefully it will give a different perspective to testing sensors.

Here is the first test that shows the low light performance of the following mirrorless cameras: Nikon 1 J2, Canon EOS-M, Sony NEX-F3, Sony NEX-5R/NEX-6, Sony NEX-7 and Olympus OM-D EM-5. Since these cameras all look excellent at ISO levels between 100 and 800, I decided to only show ISO performance at 1600 and above. Take a look!

Canon EOS M Compact System Camera Announced

On July 23, London, UK, Canon has finally announced its mirrorless system to compete with Nikon 1, Sony NEX, Samsung NX and other brand offerings. Having neglected this market share for about 4 years now since the introduction of the first Micro Four Thirds camera, the Panasonic Lumix DMC-G1 (which may not have been the first camera to lack a moving mirror and an optical viewfinder, but offer interchangeable lens mount, but it sure was the first to really spark an interest in such a design), Canon seems to have finally admitted the potential behind affordable, small, interchangeable lens, high image quality cameras, and stepped up to the challenge. Lets see what the last DSLR manufacturer to enter this segment has to offer.
