Re: MM's

They are the same:  1200mm = 215mm

215mm is tha ACTUAL value.

1200 is the equivalent in 35mm film world... is it simply a common reference point (it assumes everyone if familiar with 35mm film equipment!).

Why the difference?  It pretty much boils down to sensor size.  A smaller sensor gives higher magnification for the same lens when compared to a larger sensor.  You trade magnificataion for quality.
