This forum is intended for discussion of Pentax 35mm and digital SLR lenses. Medium format lenses should be discussed in the
medium format forum.
Edit: the Lens Review Database system is now operational at this URL: http://www.pentaxforums.com/lensreviews/. Enjoy! It contains a listing of all geniune Pentax lenses ever produced, and allows for user reviews. A database for third-party lenses is also available.
