Sigfrid Lundberg's Stuff

A Leica lens from Minolta?
The M Rokkor lenses were produced by Minolta for their excellent rangefinder camera Minolta CLE. I aquired one of them, the 40mm f2.0, for use with my Olympus E-P2.

A neighbour, almost
I've made a new acquaintance, Gustav Holmberg, a history of science scholar with a deep interest in photography. He has started a small series with portraits of cameras he meets on the streets of the world.

Costs and benefits of standards
The Library communities have been more prone to accept and create standards than most other communities. Here I try to list costs and benifits for this.

I have smoked a cigarr together with The Book Thief
This is the story about the one and only book thief I've met

On focusing on the essentials
I acquired a socalled mirrorless interchangable lens camera in August last year. Since than I have used it exclusively with manual focus vintage lenses. Here I discuss my experience blending old and new imaging technologies.

My name is Sigfrid Lundberg. The stuff I publish here may, or may not, be of interest for anyone else.

On this site there is material on photography, music, literature and other stuff I enjoy in life. However, most of it is related to my profession as an Internet programmer and software developer within the area of digital libraries. I have been that at the Royal Danish Library, Copenhagen (Denmark) and, before that, Lund university library (Sweden).

The content here does not reflect the views of my employers. They are now all past employers, since I retired 1 May 2023.
