EF 50mm 1.8/ II between f/4.0 and f/8.0 or so... nothing bigger than f/4.0 I don't believe.
most of the shots are pretty darn shaky, this is just random footage I took when I first got the cam. I'm wondering how the exposure (especially of the dancing scenes) looks to everyone else... too dark? on some monitors I notice it's very dark but on my monitor at home and on my TV it looks fine.
It looks like it might be underexposed in some shots. Then again, it's all up to the filmmaker in my opinion. Sometimes a darker image is what you want, but it doesn't seem so in this short because it's relatively happy and comedic, so yeah, probably underexposed.
