Hello, i bought my camera for the main reason to take pictures of cars at events. (car shows, meets... whatever i have spare time for). i bought the 17-40L since thats the focal length i generally like to use the most. i have seen alot of people recommending a 70-200 f;4 L for daylight events. should i invest my money in one? since the price for a non-IS version is affordable for me. (i cant justify spending 1300+ on a lens that i use maybe once a month) im pretty sure i can do without the IS. since the pictures i take is for myself only.
