Opinion vs review?

A serious camera review will typically provide:

General product background

Detailed specifications (from the manufacturer)

Empirically measured performance date of the specified parameters

Construction, ergonomic and user interface descriptions

Comparative analysis of similar products with empirical data

Comments and conclusions ( this is where the reviewers opinions are usually stated and references made to the cited empirical data to support the opinions).

The less empirical data provided to support comments and conclusions, the less the article is a serious review and the more it falls into the area of opinion.
