All that awesome gear, and you can't use a better camera?

@WillowFox yep, you right, it shouldn’t wind. but, i took off the record
lever from it place. hence, it still works even with the lever is down. in
short words : i used only the power part from the main transformer :)
(disabled the reel part). thx a lot
