Hi guys,my question is directed towards SEL1018 and SEL1650 owners. My preferred wide angle focus distance is 24mm on full frame (so 16mm on my NEX6). I have a SEL1650 and the 16mm distance is not bad, much better than in the SEL1628 that I had before but not shiny. My question is simple, although the answer might not be: is 16mm from SEL1018 noticeably better than SEL1650's? I don't mean the technical differences; I'm curious about the visual differences in colour fidelity, contrast and sharpness. I'd appreciate any comments!
