This is not entirely true, atleast not for canon lenses.
That is only true when you use an EF (Full Frame) lens on a EF-S (Crop Sensor) camera.
For example an EF 50mm 1.8f, is effectively an 80mm on most crop sensor cameras (Xti, XSi, X1i, 40D, 50D, 7D, etc).
But a 18-55mm EF-S lens, is a 18-55mm lens on an EF-S camera.
I'm pretty sure this is the same for Nikons, they just use different codes (FX vs. DX) for their full frame lenes vs. crop.
Either way i think we are confusing the OP, i think all he needs is a LX3 and call it a day.
