There are two websites I’ve used extensively for information about camera bodies and lenses, and in the process helped my own understanding of some underpinning concepts: contains comprehensive reviews and tests of nearly every digital camera made (including tests of dynamic range, as touched on today). Has some limited lens and other reviews too. contains a database of many but not all SLR style lenses of the main brands (zoom and prime), with test results that show clearly the apertures at which they excel – or not. Worth reviewing for your own lenses if they appear here.

Best regards,
