Thanks for your input. But the 70-200 is not currently on my list.
And I would not consider and third party lens.
If I dont go for the current 24-70 upgrade I will probably do nothing at the moment.
also, I do intend to get a 5d3 eventually. Just not now. It's too expensive and bodies depreciate much faster. I'm just not ready to buy it right now.
I shoot a wide range of events there's no one "kind" and besides the different kinds of events and parties are more similar than not. And the 24-105 is fine for most of that. I would love to use more primes and events but its just not practical. At best I can carry another prime on me and every once in a while I shoot a whole event with just 1 prime.
So, I need a mid range zoom. And since I need a midrange zoom that's what is on my camera body all the time. Although I don't need a better zoom for most events, I feel it would help me out in all situations since that is by necessity the default lens.
I dont do a lot of weddings, but when I do I imagine the 24-70 would be much better and I just rent the 70-200
A longer lens would be nice, but just not absolutely needed enough to warrant such a large expense.
