I just brought a PENTAX K-x and looking for a flash that able to reach 200 Ft or like 16 storey high, I have 500mm tele lens BUT I broke and not able to buy a Pentax, Canon EX580EX II or Nikon type of flash.
I need it for bird shooting as sometime as high as a Pine tree (over 10 storey high), any recommendation for a cheap flash? I have look around and seen like Nissin etc but don't understand those setting/specs as a newbies.
Please give me some help and recommendation and I could afford $100 approx.
Thanks very much
