I currently have a Canon 70D with an 18-135mm IS STM lens. What would be considered to be an upgrade? I am looking at image quality rather than speed, as all of my photography is scenic rather than sporty. Having said that, the Sigma 17-50mm f2.8 has reported super IQ. Do IS USM lenses have better glass than IS STM lenses?
Thanks in advance
