This website is continually being upgraded, sometimes in response to questions sent to me by visitors.

New features include:

• information on further lenses (located in the lens data section for the manufacturer in question)
• reviews of further lenses that I have tested (located in the lens tests section for the focal length in question)
• more information on accessories
• additional facts and illustrations on lens data summary pages
• many new illustrations
• answers to questions that I have been frequently asked
• updated links to other websites
• Video tutorials.  To find these quickly, go to the upgrades page.

Enjoy your visit, and do come back to visit me here regularly!
