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

Interests:
- rangefinder accuracy
- Camera patents
Works in progress
- Article on Series Filters
References needed: While most series size filters had plain metal mounts. Towards the end of the era of series filters several manufacturers started making screw-in series filters that didn't require a retaining ring or hood to hold them in place. If these are used with some lenses the original hood may not fit. (reference needed.)

- Article on Mercury Cells
Mercury cells came in number of different sizes including the 625 size (i.e. PX13, EPX625, RPX625, KX625, HD625, PN625, RM625, 4625, H1560, H-D, MR9 and the like), the 675 size (i.e. EPX675, HD675, KX675, RPX675, MR44, H-C and the like), the 400 size (i.e. E400N, EPX400, KX400, PM400R, PX400, RM400, T400N, V400PX and the like), and others. By far the 625 size is the most common.
To do list
- Leica M8 rewrite
- rangefinder accuracy math
