Re: +3", + $1,250., 35mm ff same as 24mm aps-c??

Are you saying that standing same distance away from group shot, both RX1 and RX100, angle of view of 35mm ff and 24mm aps-c is the same?

the review of the 24mm lens says: if that lens was used on a asp-c sensor, it would be 36mmm equivalent.

To put it in another way, if you had Sony NEX-7 with Zeiss 24mm lens, and RX1 with its Zeiss 35mm lens, you'd get the same field of view. This is, of course, an approximation since the crop factor for NEX-7 due to its APS-C sensor is 1.52x.

So, the Zeiss 24mm on NEX-7 would cover the same scene from the same spot as 36mm lens on FF would (so, RX1 would be negligibly wider).

The same applies to Depth of Field. Using 24mm f/1.8 on NEX-7 will compare to using 36mm f/2.8 lens on a FF camera (So, RX1 will have a shallower DOF).
