Regrettably my battery was dead after only a few pics because I forgot to charge it the night before. So I'm only posting 1 photo. its made by a company called Rising. http://www.rising.co.kr/ Bought mine from B&H in New York. The documentation lists it as 18mm focal length, f 1:82! This pic was with a 1/4 second exposure. Note the spots, your sensor has to be spotless!
