The Industar-61 L/Z 50/2.8 MC M42 macro lens from the Soviet LZOS factory features an optical structure with a Zeiss Tessar design, consisting of 4 elements in 3 groups. This lens can produce a distinctive six-pointed starburst bokeh between apertures f5.6 to f8. Although Christmas is still four months away, in order to capture the special starburst bokeh, the photographer had to bring out Christmas decorations to serve as the background for Santa Claus.
來自蘇聯LZOS工廠的Industar-61 L/Z 50/2.8 MC M42微距鏡，使用蔡司Tessar 4片3群的光學結構，在光圈5.6~8之間可拍出六芒星的特殊散景。雖然今年聖誕節還要4個月才會來臨，為了拍出星芒特殊散景，也只好把聖誕燈飾找出來當聖誕老公公的背景了。
