If that is the case, then the sensor would in the neighborhood of 6mmX9mm to 7mmX10.5mm?

If this describes the long dimension of a rectangular sensor, then it would seem that the camera has a sensor measuring about 17mm x 11mm if it has the same proportion as the 35mm film frame--in other words, close to exactly half the linear size of the 35mm frame. The problem is, the multiplier from the Digilux lens to the 35mm equivalent is 4, not about 2, as indicated by the figures given (7-22.5mm actual, 28-90mm equivalent). It also doesn't work if the 2/3" refers to the diagonal, as the 35mm diagonal is about 43mm, or about 2.5 times 2/3". Nor if it means 2/3 of a SQUARE inch, as that is produced by a 1.5:1 rectangle of about 25mm x 17mm, requiring a multiplier of about 1.5. > > So--what are the dimensions of the Digilux 2's sensor, and what does the 2/3" refer to? > > --howard > > -- > To unsubscribe, see http://mejac.palo-alto.ca.us/leica-users/unsub.html > - -- To unsubscribe, see http://mejac.palo-alto.ca.us/leica-users/unsub.html
