MINOLTA DUAL LENS AF Film Camera With Quartz Date Function When a CRP2 battery is inserted, the film advance, lens selection, flash, etc. will function. When a CR2025 battery is inserted, the date function will work. This is a fully functional product. The photos of the interior are not very clear, but the actual condition is clean. Please take advantage of this opportunity. I will pack it carefully and ship it quickly. ^_^ AI Description - Brand: MINOLTA - Model Name: DUAL LENS - Function: AF (Autofocus) - Date Function: QUARTZ DATE - Mode Settings: YEAR MON DAY, HOUR, MIN - Internal Structure: Film slot, Battery compartment
