Newbie here struggling to get acceptable basketball shots. After reading posts, I bought an additional lens for my canon 40D - the 50mm 1.4. Tried to shoot some shots using flash because light is beyond horrible (no windows, 5/9 overhead cans burnt out). tried shutter priority, but shutter speed stopped at 1/250 with flash which doesn't makes sense to me. Also, don't mean to be stupid, but I thought a prime lense 1.4 meant the aperture stays at 1.4, but apparently not. I turned ISO up to 1600, but thought I wouldn't have to do that with this new lens. Got some decent shots, but grainy when cropped. Without flash in this particular gym, its just too dark. Why can't I get faster shutter speed with flash? This is at ISO 1000 with no flash - shutter speed 1/250 and 1.8 aperture And this is one using falsh, 1/250 shutter speed, ISO 1600 and 1.4 I would really appreciate feedback -- I am reading everything I can, but I would like to get good shots before season ends.
