"...I also took a twin-lens Rolleiflex which I used for black and white.Despite being more bulky than the Contax and Retina it was extremely easy to use and with its superb Zeiss lens it was capable of producing pictures of exquisite quality. I took it as the South Col and the final results made the extras effort well worth while. When in recent years these three cameras were stolen I felt I had lost a very real part of history..." (Alfred Gregory, 1953 Everest expedition official photographer).
