Hi all.I have recently got a k1000 film slr from my bro's boss and becoz my bro is not really into photography,he passed it to me along with 2 lenses.The problem is i have some diffcultly operating it.I simply do not know how to use it.Im guessing it could be the battery that's dead already.Do you guys know of any online site that still teach ppl how to use that classic?thanks
