JAPB is structured in three main sections: Lenses, Technology and Business.
• The Lenses section focuses on all those articles that pertain either to detailing lenses, comparing lenses, lens mounts or are otherwise directly related to lenses.
• The section named Technology discusses photographic technology, techniques and some of the underlying theory.
• The Business section gathers together all those JAPB articles that relate to specific companies as well as the overall logic behind decisions to manufacture (or not) a specific lens.
See below for a list of Technology-related articles.
Those technologies, concepts and terms that are explainable in a few paragraphs, you will find in the JAPB glossary.
