一般閃光燈can use for both 菲林機 and 數碼機 but no TTL, some only use A mode or M mode... eg canon閃光燈cannot use at nikon ma?, i can say yes but no TTL. u need to use manual mode only. so 菲林機既用既閃光燈可以用係數碼機...... but manual mode and u need to adjust output yourself.... i use nikon SB26 for my D70s by using manual mode. it's work
