fast lenses for NX100

When I'm shooting primes, I usually don't change that much.  There's certainly no time during a play to switch lenses to catch some specific bit of action.  I like to get near the end of the field so I can get faces, and rotate through the lenses through the course of the game so I'll get play on the far, middle and near parts of the field.  You can get fun shots of the parents that way too.

These lenses are really smooth focusing.  Once you get an intuitive feel for which way to turn the ring to focus near/far, you can track pretty well.  The shallow depth of field is a blessing and a curse.  Because it's so thin, it's kinda hard to nail the focus, but having the foreground and background so far out of focus makes it easier to keep the players sharp...  The screen on the NX100 is great, but honestly it would be easier if it had an EVF to help with glare.  I also use these lenses on an old Minolta 35mm camera, and it's super easy.

I think if you stick with it to get a feel for the camera/lens combo, you'll do fine.  You might have better luck with a newer NX body, but those cost money...

One of the soccer moms asked for a recommendation of a nice camera, asking,"Which is better, Canon or Nikon?"  I looked at what was out there, asked myself how long she'd want to carry around a big DSLR, and recommended an OMD EM-10 with a couple kit lenses and a nice fast prime.  (She ended up with a huge Nikon anyway.)  From the little I've played with them, lots of current generation mirrorless cameras would do well with kiddie soccer, and one with an EVF would be ideal.
