Oh, so will I. But chances are it will still be a couple of generations away from what I'd be interested in buying. One thing I do like about the M that is different from both the Sony and Nikon MILC entries is Canon has chosen to keep the EOS lens mount. Which means that it should be easier to design an FF M. So when Canon decides to release an FF MILC, I'll be saving or selling to come up with the funds for one.

If I understand your comments correctly, you are saying that the EOS-M uses the standard EOS/EF lens mount. This is not correct.

The new EF-M mount, used on the EOS-M has an 18mm registration distance, as opposed to the standard Canon EF mount that uses 44mm. It also has a smaller throat diameter which would probably make it unsuitable for FF.

Yes that's sort of what I was saying, although I think I was suffering from a bit of brain fade at the time. It's been my impression that the M mount is the same physical mount as the EF mount, but yes that the registration distances are different, of course. So you're saying that the M mount is physically smaller than the EF mount?

I've handled an M once at a store and I did not detach the lens to look at the mount, so I've never seen a bare M mount yet. I've just assumed it was the same size. If Canon designed the M such that its throat is too narrow to support a 24mm x 36mm sensor, then this is a HUGE mistake on their part.

I use a m43 camera atm, with the Metabones Speedbooster for the Nikon mount. For some photo's using the 105mm f2.5, 50mm f1.8 ais and 28mm f3.5 H.C see this flickr set - http://www.flickr.com/photos/90643394@N06/sets/72157635434953134/

I'm very happy with this adapter and can't see myself 'upgrading' to aps-c sensor - especially with the panasonic gx7 (inbuilt evf, very decent focus peaking implementation) just about here Smile

The M mount (EF-M) has a smaller throat size than the standard EF mount.

Thanks guys for all the info. I think I'll probably stick with the panny for mf lenses and still go with the Nikon d7100 for everything else. I had a look at the Sony NEX systems and I'm just not sure about them. They seem great as far as iq goes and pretty good for the money but one thing that puts me off is the ability for them to develop further in the future. I just feel more comfortable with Nikon.
Thanks,
Brian.

Hmmm . . . your reason for passing on the NEX puzzles me. If you pay any attention at all to the Sony rumors sites, it would appear that most of their camera development these days is occurring within the NEX ranks. They just introduced the A3000, which really isn't a NEX, but it takes the same lenses and is the same technology, plus they're due to release an upgrade on the NEX 7 and the much-anticipated full-frame model NEX that apparently won't be called the NEX 9. There's a LOT of interest surrounding that one.

Will it have a viewfinder Michael?

Logic says it should, since the higher level cameras in nex series (6 and 7) already have it, and the new full frame one will necessarily be the top of the line.
