So I've been shooting an A6000 with the beginners trinity (16-50PZ, 55-210, and 35mm f1.8). I've got some year end cash I can spend on some new lenses but everything I'm seeing seems to imply there aren't any mid-range (say $500-$800) upgrade lenses. I'm used to the Canon and Nikon world where there are solid first upgrade lenses (for example the 18-105 or 18-140 Nikkor). Does e-mount not have that? I tend to shoot wide and was looking at the Zeiss 16-70 for example, yet real world photos don't seem to really show a big improvement over the 16-50 power zoom. Or am I missing something? I totally understand pro's needing $1500+ lenses, but I'm looking for something that creates prints I don't mind hanging on my wall, not the Met's.
