Looking for some lens advice. I'm starting to get more into event photography and enjoy being a second shooter at weddings. Right now I have a 24-105 f4 and a 100-400v1 to cover that focal range. I'm pretty happy with the setup. I also use an 85mm f1.8 and have a couple of Speedlites.
Eventually I would like to upgrade to f2.8 lenses: like the 24-70 II and the 70-200 II. My question is, if you had my setup, which lens would you upgrade first?
On one hand, I can see using flash a lot more often with a 24-70 instead of the 70-200, so being at f4 on the wide end isn't as much of a problem. Typically with portraits, I would want to be at f4 with the 24-70 to keep enough DoF anyway. That would point to buying a 70-200 first. On the other hand, I use the 24-70 focal length a lot more often in general (while traveling, with family, etc), so upgrading that first would benefit my photography a lot more overall.
