 Shutter 



^ In photography the tools we work 

 with have about as much to do with 

 our results as our own knowledge 

 and skill. 



^ That is why those who use this 

 famous lens and shutter get such 

 universally good results. 



^ Here you have a lens with speed, 

 definition and covering power, the 

 qualities essential for the production 

 of good negatives, and having a 

 range practically unlimited from 

 swift - moving objects to delicate 

 landscapes seen in the fading light. 



fl And matched with this is the best 

 of all between-the-lens shutters. 



^ When you work with such tools 

 as these you can naturally get re- 

 sults that the ordinary lens and 

 shutter will not give you.
