I like cameras. I like using them. I like learning about the technical details. I like repairing and modifying cameras.

Camera interests

Cameras:

• Leica M6, Leica CL and Leica M8
• Paxettes
• Nikons
• Koni Omegas

Interests:

• rangefinder accuracy
• Camera patents

Works in progress

• Leica M8

• 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.

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
