-if you have alot of money, go for a 70-200 L f2.8 (+- 1000 - 1500euro)
-if you have money but mostly take pictures outdoors, go for a 70-200 L f4 (no image stabiliser) (+- 500euro)

-if you don't have alot of money, for indoor, go with the 50mm f1.8 (+- 80euro)
-if you have a bit more money, go for a tamron 28-75 f2.8 (or the 17-50 but you don't need the wide angle for RC shots so go with the extra 25mm on the zoom) (+- 320-350 euro)


I have 70-200 f4 ; 50 f1.8 and tamron 28-75 f2.8


Hope this helps !!
