My cameras part 2: Praktica BX 20

Praktica BX 20SLR Cameras made by Eastern German VEB PENTACON DRESDEN was a dream of almost every amateur of photography behind the Iron Curtain. They were a symbol of much further developed technology than Soviet Union Zenit cameras. The most important was far better quality of the lenses. After 10 years using of Zenit ET (already described on my blog) I bought second hand Praktica BX 20 - a semi automatic SLR camera. I was very happy having much better quality of the photos. I took the camera twice to Scotland. I used it on my Shetland trip. Unfortunately Praktica BX 20 cameras used to have a problems with quality of the components, especially with film tranport gears. I was loosing every 3 - 5 pictures on every 36 pictures film, due to the malfunction of the gear. I stop using that camera when I bought my first Digital camera - a hybrid one, full manual Konica Minolta A1 DiMage.

My comment: In 1997 my mother bought this camera for me from a Russian or Belarussian woman who was visiting us sometimes for selling some things in the markets and bring goods to USSR. It was my first reflex camera, a real one. I took hundreds of photos using it, especially during my trips to Scotland. The camera was exposed to a hard weather and travel conditions during that trips. Finally its chassis started to leak some light, so some of the pictures had a bright smudges (about 10 from 36 pictures on each film). Later another problems appeared whit the shutter springs. I needed to hit camera with a stone or something to make it work. The camera ended on the shelf in my living room as a part of decoration.

Those specification and my comments are also added to the subpage of my blog.
