Since a few years, a lense from the 1950s has become very popular among nature photographers. It is the Trioplan 100mm 2.8 and due to strong demand it is currently valued at over 500 USD. Surprisingly, I found one in the old photo bag of my grandfather. According to the serial number this lense was produced in between 1951 and 1957 and has not been in use for decades. Despite of its age of around 60 years, it is still perfectly working and I wanted to show why it is such a famous and rare piece of equipment: its unique BOKEH or background blur.
