2012-11-18: Zeiss ZM 50mm f1.5 C-Sonnar: Portrait of a lens
The 50mm Sonnar f1.5 is a transplant from the Contax rangefinder
world. A real classic there. Also, it is indeed a personality with a
focus shift.

2012-05-14: On colour
When a subject contains vidid colours, I invariably transform the
photo to black and white. If there are few I usually preserve colour. Unless
there is special conditions that make me feel that colour is important. For
instance, when the image contain vivid colours.

2010-12-02: A tale of two lenses
Here I discuss two lenses. Both are very new. I've owned them less

respective companies building them. But appart from that they differ in
almost all aspects. Even in the very idea behind their existence.

NB
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.
