A few days ago i'v bought myself this cheap SUNPAK PZ42X external flash...it did'nt come with user manual but i'v manage to download it Somewhere from the internet.(I did'nt remember where)..The thing is even with the user manual i'v found that this flash was so hard to use.its really giving me the headache...I'v even search Youtube for the tutorial videos but yet come out with these two videos that not really helping me out in solving my problm.....have any of u guys in here use that particular flash before,even now?I really need help here...A step by step video tutorial would be best...on how to use it/getting started that is..
