- Article on series filters, references needed: Many cameras and lens use Series Filters. Series filters are glass filter in a metal mount distinguished by the absence of threads. The sizes in the series filters are denoted by a number. The number is usually in roman numerals for integers and in arabic numerals for half sizes.
From the 1930s through the late 1970s, filters were also made in a standard sizings known as series. Theses filters are round pieces of glass or resin with an unthreaded metal mount on their circumference. The filter is attached to the lens between two thread rings. Adapted from Wikipedia.
The diameter of the filter for each series is:
Series Diameter (mm) IV 20.6 4.5 25.5 V 30.2 5.5 35.9 VI 41.3 VII 50.8 7.5 57.0 VIII 63.5 IX 82.6
To do list
- Leica M8 rewrite
- rangefinder accuracy math
