The 24-105 is my fastest sold lens, after only 6 months for the great 28-70 2.8L which is out of production, but superb!
- Heavy vignetting on a 5D at 24mm & 105mm, every picture needs correction, or you have to use the lens profiles in PS to correct it automatically.
- the bokeh was not so soft (rather like f2.8 for portraits, I do a lot of portraits)
- rather like less hunting, speed is always handy!
That's why I sold my last f4 lens, I try to have the lowest fixed apertures for my primes & zooms (f2.8) for more dreamy bokeh pictures in daylight or with evening lights.
It's a popular zoom due to the range, but I rather have less range and the other, more important, advantages.
So you're basically putting down this lens for the benefit of the OP because......?
BTW the 24-105 is a great lens. I use is most of the time when I'm walking around.
