Its a bit disingenuous to compare class when the feature set is as different as it is (as cameras go) due to the difference in age/generation.

What you are suggesting is similar to saying that a 2002 Accord is the same as a 2007 Altima because they are in the same class. (or vice-versa... a 2002 Altima compared to a 2007 Accord).

Look down the feature set and performance of the cameras and then tell me again that they are 'the same'
