One of the highlights will be a Leica 0-series No. 122. With the original folding viewfinder, unique film spool and take-up spool, it is probably the most original and best condition to be auctioned. It is estimated that it will fetch  €700,000 to €900,000 (HK$6.82 million to HK$8.77 million). When this camera series was launched in 1923, only about 25 pieces were produced. It was one of the major rarities in camera history.
