Hello,
I am looking to upgrade from my 60D possibly to the 7D Mark II. I currently primarily shoot with EF-S 17-55mm f/2.8 IS USM. Should I keep the Canon EF-S 17-55mm f/2.8 IS USM or also upgrade the lens to either the Canon EF 24-70mm f/2.8L II USM or the Canon EF 24-70mm f/4L IS USM? I understand I lose some of the wide angle, but I find myself zooming in and shooting in 35mm to the 55 mm range more often then not.

Please feel free to recommend additional lenses, camera bodies and ask me questions.

Thank you for looking, thank you for your help.

Bruce J.
