Olympus Corp. is continuing talks with Sony Corp., Terumo Corp. and Fujifilm Holdings Corp. about possible tieups as the struggling camera maker seeks to raise capital in the aftermath of an accounting fraud.

There's a 50-50 chance Olympus will choose Sony as a partner, and odds are that similar firms, including Terumo, may invest in Olympus, Chairman Yasuyuki Kimoto, 63, said Monday.

Forming an alliance with Panasonic Corp. is "less likely," while the door is "still open" for Fujifilm, he said.
