The ‘L’ – disease strikes again

[clemmb]

comparing to the 24-105mm f/4L IS, once you get to f/4, it's more of a challenge to get good OOF blur,

I see a lot of comments on the f4.0. With the IS I handhold available light in most churches when I am doing weddings at ISO 800 & 1600 and get great results. As for OOF blur at 105 f4, I am very pleased. I see a lot of comparing this to the 24-70 f2.8. I have not had the opportunity to compare the two myself but the comments imply that you can get better OOF with 70@2.8 than 105@f4.0. I am skeptical but am interested if someone can do a side by side comparison.
