Battling falling prices for its compact cameras, Ricoh hopes to establish a presence in the profitable upmarket single-lens reflex camera segment, the Nikkei business daily said.

The deal will go through in October, Hoya said in a filing to the Tokyo Stock Exchange.

Hoya, which bought Pentax in 2007 mainly to gain access to its medical technology, had been widely expected to sell off the camera business.

Pentax is the world’s tenth largest digital camera brand by shipments, with just 1.5 percent of the market, according to research firm IDC.

Sales of Pentax cameras dropped just over 13 percent in the year ended March 2011, amid fierce price competition in the compact camera market.

Copier and printer-maker Ricoh, which aims to shed nearly 10 percent of its workforce to improve profits, also has a digital camera business, but sales are too small to feature in global data.
