I'm an amateur photographer. The only times I don't shoot for "myself" so to speak is when I volunteer to do events. These have ranged from big company functions in hotel ballrooms to a relative's b-day party.
I've been using my 24-105 with a 430ex with great success most of the time. But I've also encountered situations where the room is just too large with ceilings way too high to effectively bounce flash. So I'm left relying on f/4 and my 6D's high ISO capabilities. I've tried to solve this issue with prime lenses, but I found it just doesn't work out well for me when shooting events. I like the versatility of a zoom.
So I'm thinking at this point to get what I want I need to use a 2.8 zoom. However, this also presents some compromises. I love the long end of my 24-105. It allows me to take shots without being too obtrusive, so I end up getting a lot of shots in the 80-100 range. And thanks to IS I can shoot shutter speed as low as 1/50 as long as my subjects are still.
I'm doing this non-paid, so adding a lot of gear is not an option (so don't suggest another body with a 70-200 2.8 and a body with a 24-70 2.8. I know that's ideal but not realistic for me).
The options I'm considering are:
(1) Getting the Tamron 28-75. It's inexpensive, and I'll keep that with my 24-105. If it's a venue where I know I can effectively use flash, i'll just take the 24-105. If I can't use flash, I'll just take the 28-75 and zoom with my feet.
(2) Save a bit, replace 24-105 with Tamron 24-70.
(3) Save a bit more, replace 24-105 with 24-70ii.
So which of these 3 options sounds the best?
