One of my friend looking for a first mirrorless. He is planning to go with EOS M system as it has a 22mm lens with F/2. He found that older models are cheaper than new M3. He found all 3 models bundled with EF-M 22mm f/2 lens with out kit lens. He doesn't want kit lens. He is going to be 35mm shooter for sometime.
Can you elaborate the difference between these 3 versions of the body?
Thanks

I currently own both the M as well as the M2. While I checked out my brothers M3 I cannot comment in detail on it.

M2 is a bit smaller than the M, but feels a slight little bit less sturdy. The cover for all the ports is OK on the M but very flimsy on the M2

Sensor is the same, and I have not seen any difference in IQ between M and M2. While there are feature comparisons on the web I won't try to replicate, the M2 has Wifi remote control over the M, which I find very useful in some situations. (Instant sending of pics over iPad or iPhone)

The over and over debated AF performance of the M series ist actually significantly better on the M2. While it will never be an action cam, I'm OK with the M2 where the original M left me frustrated in situations like low light or macro. I have no scientific test, but personally the M3 AF did not feel more snappy or more accurate to me.

From a form factor point of view I prefer the M and M2 over the M3. I have a FF DSLR for times when needed, and as small as possible is the gap I am filling with the M2 now. If the M3 was the same form factor as the M2, and would have shown more noticeable IQ and AF improvements, I would have gone for the M3 without a doubt.

FYI: I bought the M2 after the M3 was released, and did not regret the step. Now I'm waiting for the M4 or M5 with A6000 like AF
