well i have a nikon d50 just 6 MP but good enough for me. the reasearch that i did pretty much said the lens for the nikon was really good and i had an old nikon f series so i still wanted to use my old lenes
as for the flashlight i could have done that but i would have to jump off a roof to do it i think i might be easier to just do it when its more busy like tonight
just make sure you dont see your shadow its scary sometimes
