Lens Technical Report on SMC Pentax FA77mm F1.8 Limited and FA43mm F1.9 Limited

Almost two years ago, someone at the DPR Pentax forum discovered the above technical report at the Science Links Japan..

A Japanese forum member then searched the publication from his library and he posted the scanned copy of the whole report, in Japanese.

There are six pages of the report. The forum poster further human translated the first 3 pages of the report to English (via here and here), here they are:-




The remaining three pages were left un-translated, however. If you read Japanese, you can continue to read them here:-




I found that the article to be very interesting and it worths reading for all Pentaxians, especially for those who own the Limited lenses. Enjoy!
