I got the 5D3 kit and never really fell in love with the 24-105. It was never good enough. However, over the last 9 months i've also picked up the Sigma 35mm 1.4 and Canon 70-200mm F/4 IS and love them both. So where i once thought the 24-105 would be my go-to kit, I pretty much never leave home without the 35mm and 70-200.
I've tried a few times to use the 24-105 only, but i'm always left wishing i would have brought the other lenses for their superior image quality and reach/aperture. Its come to the point where i'm seriously considering selling my 24-105 because it literally has left the house twice in 2013. If i hadn't invested in some expensive 77mm filters when I first got it, it would have been up on eBay already.
With the 35mm and 70-200mm f/4, I really fell like i can shout about 95% of what i want to shoot. For that last 5% i'm trying to decide on a wider lens for lanscapes or a macro lens. I'm interested in both, but don't shoot either all that often.
