Conclusion: I've owned 6-7 Canon bodies and 5-6 EF L lenses. Love this little camera. Digic 5 processor and APS-C in a little tiny package. Great little lenses and with the adaptor can strap on my 16-35, 70-200IS2, EF 35-350, whatever. All it is is a great sensor and processor that you put on your monstor lenses, or a tiny little camera that basically takes the same pics as a 7D. Built like a tank.
Pros: pictures as good as a 7d, tiny and light, dirt cheap as of 3-2014
Cons: not a full size sensor, can't burn date into picture easily, wide zoom is pricey, can be hard to hold no good grip place
Excerpt: My Canon S105 was just not cutting it for me. It didnt have a place for my flashes, it lacked great ISO performance and it didnt have the kind of quality I was looking for. While it could fit into my pocket, it was just not cutting it for me. I saw the Canon EOS M for sale on B&H with lens for $350 so I got that deal. There have been many reviews on the internet about how this isnt that great of a camera.
Pros: Excellent image quality for both still and video images. Many manual overrides, when desired, for the extensive auto functions and modes. Photo RAW; 2:3 format that is consistent with Canon's pro cameras. With 22mm lens it's a compact, light camera.
Cons: There is no effective rapid-fire of images as compared to G series or pro-sumer Canon camera bodies.
Pros: Great camera, relatively noob friendly, touchscreen, amazing quality of pictures, the lens base is metal and feels high quality. (same with the 22mm I bought as well, great weight and quality). Touchscreen works well. PRICE: bought this already low priced camera on sale for a fraction of the retail price (about 1/3 of the price) , but I think it takes some pretty amazing pictures that could rival the rebel series. Great bang for the buck.
Cons: Small, the grip might be lacking if you are used to other cameras. Even though the camera might be 'just as good' as some of it's bigger brothers, it looks ridiculously small. Lastly, the reviews for the seller are not all that good, and caused the deal to smell pretty fishy.
Conclusion: Hate to see all of the neg reviews but industry-wide, it has helped drive prices down so low, this was just too darned good of a digi-cam to pass up! 1, with the EF lens adapter, this is a mini powerhouse! 2, simply incredible video - breath-taking color & resolution! 3, this isn't an action camera - yet. I have dSLRs for that. Sure, Canon has work to do on a newer model - but for what it is, it's a superb camera.
Pros: quiet, Quick Start-up time, excellent image quality, Superior build quality, Bright LCD, Solid Operation, Lightweight/Portable, ef lens adapter available, incredible video
Cons: Missing features/settings, Short battery life, Complicated controls/menu, needs a better remote, no articulated screen
Conclusion: Like many others I purchased the EOS M around Black Friday at what I figured was a steal. It's incredibly well built and has every feature one could ask for. Obviously the most glaring issue is, of course, the slow autofocus. Not sort of slow, not relatively slow to other cameras...extremely, almost throw-throw-it-in-the-garbage, slow. As big and relevant of a camera corporation as Canon is I can't imagine how this design could leave their engineering dept?
Pros: good battery life, Nice features/settings, Quick Start-up time, excellent image quality, Superior build quality, Bright LCD, Lightweight/Portable, Simple controls/menu, easy to use
Cons: noisy, horrific autofocus, terrible firmware support
Excerpt: Just bought Raynox DCR-250 and tried to 22mm and 18-55mm on my lovely Canon EOS M. Here it is the picture taken from those lenses at closets distance. For better stabilities and precision I'm using macro focus rail. BTW the ruler is in cm. Sadly the result from 18-55mm has a little shadow at all of corners.
