I have (temporarily) both a NEX 7 and an EOS M so thought I would do some comparisons. Both are very nice cameras, but I think will appeal to different sorts of users. The Canon is better than the reputation it has gotten on various camera forums, but yes, the AF performance leaves something to be desired. Basically, Canon could have omitted the AI Servo, it doesn't work. That said, I loved the feature that enables you to zoom in x10 and focus (AF or MF) on a fine spot. Single shot, flexible spot AF worked pretty well. Using the touch to shoot seemed quite quick. The M build quality is excellent. The lack of built in flash is a downer for when you want fill flash. While the 90ex flash is tiny, it adds considerably to the M bulk. It will, however, act as a master to any modern Canon flash (it worked well with my 430ex II for example). The adapter worked well with my 50 1.4, but AF wasn't as fast or smooth without the STM lenses.

The NEX 7 has been around for a while now, but is still Sony's top of the line mirrorless body, boasting a 24mp sensor (compared to Canon's 18mp). It has a hugely customizable tri-navi system, but is encumbered by an awful menu system. Sony really needs to get somebody to straighten that out.

IQ from both cameras was very good. Both can go toe to toe with any APS-C dslr on the market in the IQ department. (They just can't AF with one). I shot comparisons from both with the standard Sony 18-55 OSS and the Canon 18-55 STM. I also threw in a few from the Canon 22mm. I'd never really found the Sony 18-55 lacking when I had a 5N, but I think the 7 is more demanding. In any case, the Canon lens seemed to be the better performer. The Canon M defaulted to a slightly warmer white balance (both were shot on AWB) and also seemed to expose slightly darker for the same exposure settings.

Although Sony has better sensors than Canon with respect to dynamic range, the 24MP showed in a higher noise pattern for the Sony. I suspect down-sampling the images will even this out, but I didn't have time to try that.

This sample, at 55mm on each kit lens, but with the popup on the 7 and the 90ex on the M, shows the Canon lens to be a bit better IMO:

All in all, both are very nice cameras. I think the 7 needs to be used with better lenses than the 18-55 to get the most out of it. It is more full-featured and has outstanding resolution. On the downside, it's larger, noiser, and can be hard to figure out (steeper learning curve). I don't think anyone who has a 7 should switch to the M. I think they would find it frustrating. But for anyone buying into a new system, it's worth a look - provided Canon continues to support it with new lenses and products.

Interesting. I also found that the EOS-M kit lenses are high quality. For example: the 18-55 EF-M is about the same quality as the 15-85 EF-S and almost as good as 17-55 EF-S at similar apertures.

But I want more lenses for the system, at least there should be a 35mm prime.

And I want a similar Speed-booster for the Canon mirrorless.


Fuji XE-1, Zeiss ikon, Hasselblad; I love shooting film as a conceptual idea :)

In the first example you have exact same time of day for both pics and cameras ..
in the second there is over a minute difference.
Look fishy to me ..

Also first comparison has 1/500s shutter speed for EOS M and 1/800s for NEX 7.

Yeah I was shooting on aperture priority and probably should have shot manual. Could have been a slight difference in focus point leading the camera to select a different exposure, or could have just been a difference in the exposure choices. The difference in exposure - the 7 is slightly underexposed - likely contributes meaningfully to the noise difference. Oh well - I'm not running a lab out of my home office... if I had noticed right away, I would have reshot it, but the 7 is now sold and off to a new owner.

El Pic - I don't know why you would think that's fishy.

The ISO 3200 example shows 2/3 stop underexposure on the sony, which can easily account for more noise. (1/500 vs 1/800 shutter speed)

There is - the 22mm f/2 is 35mm equivalent and is an excellent lens

And the 40mm f2.8 with the adapter might as well be built for the system. It's still smaller than the kit, and with the STM focuses similar to the 22mm.

The 40 works great on the M. Here's my M lineup (taken with the 22mm), three lenses - three mounts:

+1
I found the 40mm STM indeed is good mate for the little M guy if you have the EOS adapter:

liked the OP, I have found the EOS-M's ISO noise is much cleaner (also smoother) than my other NEX-5N and Lumix GH-2 mirrorless camera (which I still have those)
