1、Rectsr （because the a kinda, sorta, looked like an s）, and the ignorant call Rectal （in an attempt to belittle their quality）. Some even claimed that these lenses were filled with water, instead of glass - no kidding! Undoubtedly, these Fuji lenses were modeled after German,Tessar-type lenses that w

2、ere common in Japan before the War. There were at least four of Fujis Rectar lenses that were made for what we nowadays refer to aslarge format. The early Rectar lenses were made with uncoated glass, but it is possible that all Rectar lenses were uncoated. Afterall, the first, coated,Japanese lenses

3、 did not appear until Minolta produced them in 1947. It might be that when Fuji added coating to their lenses that they changed the name toFujinar （see below）. It is possible that there were other focal lengths than those listed here, but not too likely. The Rectar name was also used on Fujisearly e

14、 SC means Single Coated, but this is unlikely since Fuji had not developed EBC coating at the time, soall of their lenses were single coated.
