I'm a 6 month old noob and an amateur. I just get invited to parties cause I can take better pics than most of the idiots I hang with 
Long story short, I took my 5Dc, 24-70L (rental), 70-200 F4L, and 580EX2 (rental) to an indoor party last night.
You know, I see so many people online with the 24-70L (especially pros and wedding pros) that I thought it would make the skies part, a light to shine down, and make angels sing. Well, that didn't happen. It did take nice pics, and admittedly the 70-200 would not have been able to do the BIG group shots (~8-12 people in one big curve), but it just was not tight enough. The ring was too tight and I just wasn't you know, feeling the Force or anything.
I eventually removed the 24-70 and put on my 70-200 F4(!) and it was like magic :P The F4 worked better than I expected indoors (incandescent) and was SHARP and colorful; wish I could get the same sharpness with my 7D :P (yes I pixel peep
) The 580EX2 was a huge help as well; thassa nice flash.
If I was a pro, I'd use a 24-70 sparingly and have the 70-200 (2.8 tho) on the camera all the time. Not taking any kind of dig at the 24-70 fans out there but I just did not get the high I was so hoping for. The high turned out to be my trusty beauty who'd been there all along.
So have I actually established a 'style' now or is it just because the 70-200 is all I have been shooting with for the past 4 months I'm just too used to it? Dunno, just wondering out loud; thanks for listening.
