Hidden under the Ifba 500 is a Halina 500, manufactured in Hong Kong by Haking, a photography giant.

Haking Wong, Commander of the Order of the British Empire, formerly known as Huang Zuyi, was born in Hong Kong in 1906 and, except for the period of Japanese occupation, spent his entire life in the British colony. He was the son of a wealthy Chinese from Thailand. He lived in Thailand during his childhood and returned to Hong Kong at the age of eleven to study at St. Stephen's College. After graduating from high school, he entered the rubber industry and manufactured thousands of athletic shoes in Kowloon. He later became interested in the emerging field of electronics and became involved in other businesses, including textiles. At one point, Haking's factory in Hong Kong was the world's largest producer of toothbrushes. His activities also extended to the ship repair industry. By the time the war broke out, Mr. Wong was one of Hong Kong's most promising entrepreneurs.
In the 1950s, Hong Kong began developing its manufacturing industry. In 1956, Haking Wong and Mrs. Pauline Chan co-founded Baoyuan Foundation Co., Ltd. Over the next five to six years, Haking Wong wanted to find a more competitive and high-tech industry, transitioning from the plastic industry to the manufacture of optical instruments.
In 1957, he produced his first simple camera. At that time, photography was still in a relatively formative state. Since then, technology in camera production has made significant progress. Haking Wong became the Henry Ford of Hong Kong in the world of optics. Yet, he was over fifty years old when he made this leap into the dark—or perhaps we could more accurately say into the darkroom. His specialty was the production of cameras with integrated electronic flash in the 110 and 135 formats. He made improvements to shutters, prisms, and lens coatings. He also ventured into manufacturing binoculars. Technology that was once the preserve of West Germans and the Japanese was no longer so. In 1972, the company employed 5000 workers in 9 factories in Hong Kong, 3 in Macao, and one in Taiwan. At that time, it was the largest producer of binoculars. Haking also produced cassette tape recorders.
Because Haking Wong was a pioneer in the manufacture of optical instruments such as cameras and telescopes in Hong Kong, he later became known as the king of optical instruments.
At the same time, he was a passionate philanthropist for education and public welfare. In 1977, he made a donation to establish the Haking Wong Institute of Technology, now renamed the Hong Kong Institute of Vocational Education, and in 1983, he funded the construction of the Haking Wong Building at the University of Hong Kong. In addition to Hong Kong, Haking Wong also invested in the construction of the Haking Wong Bridge in Xinhui (1992).

Haking Wong held several titles in his life, such as President of the Hong Kong Chinese Manufacturers' Association. Haking Wong was decorated with the Order of the British Empire in 1968 and received an honorary Doctor of Laws degree from the University of Hong Kong in 1980.

Haking Wong had three wives and a total of eleven children. After his death in 1996, his family members repeatedly made headlines due to financial conflicts and lawsuits. In December 2000, three of his sons filed a petition with the High Court to request the liquidation of the Baoyuan Foundation, ultimately leading to the company's exile to China. In 2002, Titan Continental Ltd purchased over 70% of the shares of Baoyuan Foundation and removed the family descendants from the board of directors.

Since 1957, Haking has been the only local company to successfully produce cameras and binoculars. While the company's name comes from Haking's personal name, the early cameras were named Paulette, derived from the name of his co-founder associate, Pauline Chan.
