Film Size Chart

v1.0, 2005.05.31

 

The following tables compare different types of film and film cameras. Even though digital is rapidly replacing film, there are still some limitations which could take years for digital to overcome. It is important to realize that most of today's digital cameras are being compared to consumer grade 35mm film cameras. A single frame of 35mm film can only hold so much information but as you can see, other types of professional film can capture details that are beyond the ability of any digital camera costing less than $20,000.
