This section will be always under development, being updated continuously according to questions asked by AOHC members and guests accessing this website as well as discussion in Pentax Discuss and Spotmatic Users mailing lists.
In case you don't find a proper answer to your question here, you can email us. Should your question be of general interest, it will be also added here. Please don't ask questions needing a whole book to be answered. If you have such questions (and I really hope so), you can probably enjoy AOHC membership. Corrections and/or contribution to improve this page are always welcome.
