Well, I really don't do it professionally right now. I do some side jobs and little things. Shot a couple weddings and engagement sessions. Does the 2.8 really make that much of a big difference in low light or like night shots?
f2.8 is a full stop faster than f4.0, so yeah it's a huge difference. You'll be able to double you shutter speed with the 2.8. Now, imagine shooting a wedding where you can only achieve 1/125 with the f/4. Possibly will turn out ok, but with the f2.8 you could have the same exposure at 1/250.
Another factor to consider is that you will lose your high-precision center autofocus sensor with any glass slower than f2.8. Lenses with maximum apertures slower than f2.8 cause the high-precision center autofocus sensor to change to a standard precision sensor.
Yet another bonus with the f/2.8 is that you can throw the 1.4x teleconverter on and have a very usable 98-280/f4 lens if you need a little more reach.
I don't understand why people are so fearful of the weight of the 70-200/2.8L IS. Yeah, it's a heck of a lot heavier than a small prime or the kit lens, but this lens is handheld routinely by wedding, portrait, sports, and photojournalist photographers all over. A few guys I shoot with routinely handhold the 300/2.8 IS or 200/1.8 for an entire football game. I prefer a monopod for the 300/2.8, but sometimes will handhold it for a quarter or so.
