284,000 Cyber Shot DSC-T5 cameras sold in the United States, Europe and China as well as 66,000 sold in Japan have been recalled following the discovery that the case may warp leaving sharp edges.
Sony is offering to replace the casing located on the base of the camera at no charge, where the problem occurs.
The problem arose about one month after the model first went onto the market during September 2005, Sony spokeswoman Ryoko Takagi said. About 30 customers in Japan and "several" others overseas have since reported finding the defect, with a number saying they received small cuts and scratches from it, she said.
Customers are advised to check the model and serial numbers of their cameras to see if they are among the affected products, the company said in a statement. The problem only affects cameras with numbers between 3500001 and 3574100.
