【Product Name】 Nikon D90 【Condition】 The exterior has no noticeable scratches or marks, and is in relatively clean condition with minor scratches and scuffs from normal use. The cover for inserting the SD card is stiff to open and close. 【Operation】 When the shutter button is pressed, the mirror stops halfway, and an error message appears. Sometimes it is possible to take pictures. The motor sound can be heard, so I think the pinion gear that operates the mirror is damaged. How about it for someone who can replace the pinion gear? 【Included Items】 None.
