Let's be clear!  Are you knocking Sigma fanboys?  I don't have a single modern sigma lens, from the Global View Era.  But I might qualify as a Sigma 50mm f/1.4 art fanboy since they've managed to sell me on that one - and I've never even seen one! 


Or do you mean Canon L lens fanboys which I might be someday.  The problem is, I've only used three L-lenses, and nothing as iffy as any version 24-105 F/4L.  Since the 24-70mm F/xL all seem well received, I don't think I will go with a ? for the extra 35mm on the long end.

First, making sarcastic fun to me is not "knocking" but I'm no native speaker so you could as well describe what I did precisely in your words.

Second, I mean fanboys in general. As long as a manufacturer surprises me by doing things better than I expected, I'm pleased and on the step of becoming fanboy. I cross that step when I defend an objective disadvantage with slightly weird reasons, like "yes, IQ could be better, but the pouch they put in the box is very nice"
