In 120 medium format film the rectangular frame option is favourite by many over the square one.
The vast majority of cameras are 6×6 and 6×9. Other options are 4×4 , 4×5.5 , 6×4.5 , 6×7 , 6×17.
The 6×4.5 is one of the best options combining the quality of medium format the rectangular frame and 16 frames per roll of film.
The choices in cameras are not so many and if searching for an easy way into 6×4.5 an old folder is to be considered.
The above photograph pictures a Konishiroku Pearl II camera.
Konishiroku was the company that later came to be the well known Konica.
A little search on the net is all needed for the full history.
The Pearl II features a coupled rangefinder, a 3.5/75 Hexar lens and a Konirapid-S shutter with speeds from 1s to 1/500 and B.
This model is from the early 50’s and was not in good condition. The lens was heavily occupied and a test roll revealed a small hole in the bellows, the shutter was sticky and the rangefinder was not correct.
The bellows hole was patched, that was the easy part. The lens cleaned up from the visitors leaving only some permanent inhabitants.
The hunt for the rangefinder fault cought a loose mirror. That was a bigger pain for it is a tiny mirror that will not forgive the smallest movement.
The last pain was the shutter. That was the first time i opened a folders shutter. It was not easy. When you come to a full frustration you need to let it, relax and start again. Somehow you will get into its theory of operation and find what’s need to be done.
For all us crazies with old cameras it is a great pleasure to ressurect one to a usable condition.
