what is IS? h:

 

image stabilizer (tion)

 

You going to need 3 things.
1. fast lens (f4 or faster)
2. fast focus speed
3. money to buy the above 2.

also IS isn't necessarily necessary. you can use a tripod or a monopod. the blur that comes from tracking a subject wont be reduced by using IS. faster shutter speed will reduce/remove it. personally i prefer to track the subject and use a slower shutter speed to blue the wheels/back ground. I use a mono pod if I am standing in one place with VR (Nikons version of IS) turned off or set for horizontal tracking. If i'm not using a mono pod and/or on the move I turn on both but most of the time I don't see a big difference in the photos.

 

f/2.8 or go home h:

 

it's like 2x the cost of the F4 and the F4 is already about 2x the cost of the lens he posted :chuckles:

 

:rofl: i know.

i really want the 2.8 h: but it's so big it's not like i could take it to any pro sporting events, which is what i'd really want it for :hs:

 

Both are out of my price range. Keep in mind im still a noob.

look for used lenses. there is nothing more expensive than cheap lenses in the camera world.
