About the Imaging Resource Digital Camera Database: We believe this is the most comprehensive database of its type in the world. It incorporates not only information supplied by manufacturers, but critical performance data such as shutter lag, cycle time, and power consumption figures for cameras we've tested.

(All non-manufacturer-supplied data is copyright 1999 - 2024 The Imaging Resource, all rights reserved, and may not be duplicated without express written permission.) This is also the ONLY camera-features database with up-to-date "street price" information, updated approximately biweekly.
