CELOSdb: Canon EF lenses and other stuff database

J.L. Colwell, Canada, 2005-04-30




The Canon EF lenses and other stuff database, CELOSdb, includes contemporary prices and physical specification data for over 300 lenses and other stuff, including: all Canon EF prime lenses; all Canon EF L-series zoom lenses (plus a few others); selected EF-compatible “third party” lenses; and, other stuff including; teleconverters, flash, and macro accessories.  The prices are mostly for used equipment in excellent to mint condition, based on hundreds of eBay sales and online list prices at over 90 camera stores.  The price information was gathered over seven months from October 2004 through April 2005. The database also lists physical specifications such as minimum focus distance, weight and dimensions.  The database and this document are distributed in .pdf format, and the database is also available as a password-protected MS Excel .xls spreadsheet, and as .csv comma-delimited text files.
