Starting with; I am a relatively inexperienced and newly appointed photographer which must be remembered by the reader of this review. I took the EOS M before EOS M3 which I was incredibly happy with. The change was involuntary when my EOS M was stolen. I shoot almost no action because I do not know how the camera is there. The EOS M felt sometimes like a point-and-shot camera which could be limiting but with M3, it really feels like an SLR. What I lack is mainly about more original objective. There's lots of third-party manufacturers so really missing nothing, but it would have been interesting to see Canon bring forward a few more and then preferably with aperture of around 1.4.
I am very pleased with the EOS M3! All the proposed improvements I had have been fixed. The foremost is that the controls have been moved out of the house which makes shooting so much easier to control. Perfect on the programmable keys too!
I found that the EOS M delivered a fabulous picture quality and I must say that the EOS M3 is a bit sharper. I shoot mostly with pancake (22mm), but with the EOS M3 I think also kitobjektivet (18-55mm) are really good. I would absolutely recommend buying 22mm lens. It is bright and does wonders even for an amateur like me :-D It costs 700 SEK type on Ebay, corny worth.
The new grip is really good! The camera is very comfortable to hold, and because the controls are equivalent to those of a standard DSLR camera, it is quick to do / see settings and a big plus for the programmable keys that truly personifies the camera. The camera has become a bit heavier and larger which I think is a shame because it takes a bit of portability.
The screen has gone from fixed to floating, which at first I thought was going to affect me at all, "it needs to will not", I thought. But alas I was wrong. It is very comfortable with a folding screen. Especially when you want the camera closer to the ground and can only tilt the screen and get a perfect picture of what you're shooting.
+ Brutally good picture quality, especially with 22mm lens
+ M3 version really feels like a compact DSLR with great controls!
- The camera has become a little less portable.
