Two Unquestioned 
Successes 
The famous GOERZ DAGOR F/6.8 is an 
unquestioned success! For over twenty-five years 
it has met the most exacting requirements. It is 
made to fit virtually every make and style of 
camera. 
Another unquestioned success is the popular 
convertible GOERZ DOGMAR F/4.5 — three lenses 
in one! It is a fast anastigmat for reflecting- 
eameras, an excellent studio-lens and ideally suited 
to commercial and landscape-photography. The 
demand exceeds our manufacturing-capacity — 
enough said! 
These two unquestioned successes embody true 
GOERZ QUALITY throughout — no finer anastig- 
mats are made. Talk it over with your dealer. 
Our descriptive matter, includiig our other suc- 
cesses, is yours for the asking. Get that “better 
lens” right now!
