18mm wide in 3:2 ratio would make it much smaller than APS-C.
Perhaps it is the G1x sensor, that would make a lot of sense, that one is 18.7mm wide but I don't believe that is the right ratio.
I've always e-speculated that Canon's mirrorless would use the G1X sensor, if the endless stream of DSLR's with the 18mp APS-c sensor is any indication, Canon likes to spread its sensor investment over multiple cameras.
This topic really raises dust. We shouldn't wine a lot if it won't have every possible characteristic, it is only the first generation. For now it obviously hasn't got an eye viewfinder and tilt/swivel screen. And it is definitely not an eye catcher. This is only a small wine.
I'm still betting it's a APS-C sensor. Even with a low-res file and my roguh measure it's too close to the officail measure of APS-C, and let's not forguet the 3:2 ratio.
Anyway from what I've read the official announcement should be this Monday.
I'm just doing the math.. not speculating anything about new sensor tech.
Also note.. the 20.2 mm is to the housing edge. That means the sensor underneath is smaller yet.
If this sensor is around 20mm wide and a 3:2 ratio, the lens would be about a 40mm equivalent lens.
If this sensor is around 18mm wide, like the G1X, then we're looking at about a 45mm equiv.
If this sensor is actually Canon's 1.6x crop sensor, and the lens is a 35mm equiv., then Sony should take notice of this lens design, because the Zeiss 24 is huge in comparison, despite being a little faster.

Remember we don't know how the lens performs or what the register of the camera is. Canon could have gone with a much longer register (as Samsung did) to make compact lens design easier, or included compensating microlenses on the sensor or accepted the quality tradeoffs that Sony did with the similar-sized 16/2.8. And the Zeiss 24 is unusual in that it is extremely telecentric, which is why it is so large and also one reason why it performs so well on the NEX-7.
Frankly I suspect the large size of the Zeiss 24 is in part a reaction to the response the 16/2.8 got, the originally shown prototypes were much smaller and it grew to the current size late in the game. The 16 gets widely panned for its poor edge performance, ignoring the simple fact that it is in fact a very good performer across most of the frame and that for the cost, it's an excellent performer. Even the Sigma 19/2.8, which is widely considered a remarkable performer, is only a little better at the edges than the Sony 16, and the Sigma is both larger and less wide, making the design simpler to execute.
Hoping the normal fast primer for NEX will be a 35/1.4 - preferably a zeiss I can dream right? Alright, cards on the table what I'd really love is the handling/portability of a NEX (the 7 is fine) and the image qualities afforded to me by the 5D + 35/1.4 distagon. Oh... and I don't want to pay Leica M9 prices (or deal with the rangefinder)... oh well, maybe one day

That won't happen anyways, Sony already does a 30/3.5 Macro for E system, they won't bring out a second one so close. I'm expecting a 35/1.8 based on the A mount optics and something longer in a ZA (I'd kill for a ZA E 50/1.4 Sonnar)

I think Sony's problem could be in the inconsistent design of the sensor assembly and how it handles oblique light rays, so they have to design the lenses to work with the lowest common denominator. Vivek on another forum took apart the NEX-7 sensor and found an extra piece of coated glass between the dust shaker and sensor that the 5N doesn't apparently have. It's all pretty odd, and I wish that Sony had a clearer handle on it. I sold the ZA 24 after a while, partly because I wasn't a fan of the size.
Judging by the pics, the registration looks maybe slightly longer than NEX, although not nearly as long as NX, but we'll see. I'm still not convinced that the sensor is a full 1.6x crop aps-c.

I'm actually hoping for a 35/2, so it is a little smaller.

From the lack of control looks like they are more concerned about not cannibalizing their APSC line than to compete against other mirrorless.
I guess it has a touchscreen so I wouldn't say so.
Sad, everyone wants to build the same low end ridiculous stuff.
I see no differentiation.
I would still say Sony is the leader, everyone else being lemmings...
