Summary: This is as close as you're going to get to a dSLR without actually buying one. The real highlight is the touch interface which makes it easy to fix the settings you need. Performance was good overall, although a little muted on an overcast day, and although the choice of native lenses remains fairly small right now, the option to add on existing EF and EF-S kit makes it seriously tempting. It's well-priced, too.
Cons: Narrow selection of native lenses so far; Muted tones on overcast day.
Excerpt: Undeniably an exciting announcement from Canon, the popular camera manufacturer has finally announced the company's first mirror-less interchangeable lens camera called the EOS M. Arguably designed for more novice users looking to upgrade the quality of their photos while keeping the smaller form factor of a point & shoot, the Canon EOS M has been modeled around a new "EF-M" lens mount.
Excerpt: The EOS M is Canon’s first foray into the mirrorless camera market that is currently dominated by Micro Four Thirds models from Olympus and Panasonic, along with Sony’s NEX lineup. The EOS M was welcomed with a collective “It’s about time…” from most of the digital imaging press, who have wondered when Canon would get around to participating in this exploding market segment.
Conclusion: In technology, we expect first-of-its-kind products to encounter teething issues. But in the case of the EOS M, Canon should not have had to reinvent the wheel. Perhaps the company is still unsure and testing the waters with this first try, or, as some have theorized, Canon doesn’t want a mirrorless model to cannibalize its market share of compact EOS DSLRs, a sector it’s strong in.
Pros: Solid construction, The use of Canon’s full line of lenses (via optional adapter), DSLR sensor, Great image and video quality
Cons: Slow autofocusing system, Time-consuming settings adjustments, No viewfinder
Conclusion: But Canon has been late to enter the increasingly popular mirrorless camera market, much to everyone’s wonder. However, with the EOS M, one can term their entrance as ‘fashionably late’. The EOS M is a very impressive mirrorless camera that rivals entry level DSLRs in terms of image and video quality, with a slow autofocus being its only major weakness.
Conclusion: Late to the mirrorless camera game, the Canon EOS M wasn't a big hit at launch -- primarily due to reports of its glacial autofocus speeds. (Something we discovered here at IR immediately.) Due to what was considered a fatal flaw, the camera was mostly ignored until recently when Canon finally addressed the AF issue with a much-anticipated firmware update.
Pros: Solid, compact build and attractive, sleek design that borrows from Canon's PowerShot compacts, 18-megapixel, APS-C sensor delivers great, DSLR-like image quality (similar to the Rebel T4i, T5i and SL1), 3-inch LCD touchscreen monitor is bright and high-resolution, Robust video capabilities, including Full HD (1080p) recording at up to 30fps with stereo audio, Manual Movie mode allows for setting and changing aperture, shutter speed, ISO and more, External mic jack, G...
Cons: Autofocus speed, though now in the acceptable range thanks to a recent firmware update, is still slower than most other mirrorless cameras, Navigation and changing settings can be confusing as it's not always intuitive whether to use physical or touchscreen controls, Limited creative filters and special effects modes, LCD does not articulate (it's fixed flush to maximize compactness), Poor low-light focusing, Slow single-shot cycle times, Below average burst speed for...
Summary: Blending the best bits of their compact and DSLR range, Canon has delivered one of the most easy to use, capable CSCs around today. While there are a couple of things that are missing on the EOS M - Wi-Fi connectivity for instance, on the whole it's a very well specified camera, with plenty to keep both the entry-level and more experienced users happy.
