Should i buy the 35L or buy the 35 F2 and use the other money towards maybe a 17-40? I have a 5dc 70-200 2.8 IS 28-75 2.8 and 85 1.8. Im mostly doing portraits/weddings. I have about 2k as of now to spend on lens and camera (going to be buying another 5dc). So ill have about 1100 left over. What would you guys do?
