    I'm looking at getting a 85 1.8 for shooting basketball in a poorly lit gym. But is it really gonna make enough difference from a 2.8 lens to the 1.8? So if I were shooting 1/250, how much faster could I shoot? I know I would like to go for the 1.4 when it comes to getting the fastest lens, but price difference won't cut it. I thought about 135 f2, but again huge price difference.

    I know there are some basketball shooters in here, any suggestions and/or tips...I'm thinking now of using the 70-200 2.8, underexposing alittle for speed, and pulling out in PP.
     
  2. f/2.8 f/2 f/1.4 so you will have 1 and 2/3 of a stop, so that's nearly 2 stops more light

    Wide open at f/1.8 you'd be able to shoot around 1/500 to 1/650 at 1.8 if you could get 250 at 2.8

    f/1.4 would give you 1/1000 but I have a feeling 1.4 and 1.8 are too little dof for sports.

    If you underexpose and then lift it in PP, you will increase noise a lot, you'd be better lifting your ISO, and then exposing correctly, are you able to use any flashes?

    Actually the difference between 2.8 and 1.8 is about 1 3/4 stop (lg 2.8 / lg 1.8 = 1.75) and as previous poster pointed out that's a decent difference.

    Instead of 1/250 you could be shooting at 1/840 or whatever is closest. Mmmh. Maybe I should get that 85/1.8 instead of waiting until I can buy the 1.4 instead...

    Thanks, looks like I'll be going with an 85.
