...that 2 out of 5 is good. So I love my 12-35 and my 35-100. That is about where it ends. The 7-14 has the crazy purple blobs and so I never use it. The 25 rattlesnakes and so I never use it. The 100-300 pretty well sucks under most conditions so I never hardly use it. I find myself traveling with just the two lenses and everything else stays at home as I find them bordering on unusable. I am so glad that I didn't sell my 5DIII and lenses. Say what you will, they just give me what I need. I may just keep the 2 good lenses as a travel kit and get rid of the rest. I have been shooting for 50+ years and never had so many issues with any "system"
