[OM] Re: What to buy, what to buy.

Those Nikonuts and Canonazis quoted are exactly that.  But your oft 
repeated Oly marketing speak statement about cropping to 8x10 belies the 
real math.

A 4/3 sensor is 17.3x13mm and when cropped to 8x10 ratio gives 
16.25x13mm for a total area of 211.25 square mm.  A Canon 1.6X crop 
sensor is 22.2x14.8mm and when cropped 8x10 is 18.5x14.8mm for a total 
are of 267.14 square mm or 26.5% larger.  A Nikon 1.5X crop sensor is 
23.6x15.8mm for a total area of 312.05 square mm or 47.7% larger.  A 
Canon 5D sensor is 35.8x23.9mm and cropped 8x10 is 29.88x23.9mm for a 
total area of 714.13 square mm or 338% larger.

Sorry, but I don't find much parity in these numbers.
