I know this has been asked alot..
I have Canon 600D with Canon EF-S 18-135mm f/3.5-5.6 and Canon 50mm f/1.8 lenses.
I'm looking to upgrade the zoom lens with something with better IQ, sharpness, bokeh and low light performance.
I read alot about those 2 Sigma lenses and I understand that the compromise is between constant aperture and additional reach.
I mostly shoot at outdoor trips / hikes, etc.. and have my first baby on the way so it'll be used for family shots as well.
I'm also using my camera for mountain biking videos, using those 2 lenses I have and some vintage manual lenses.
I need some expert advice for choosing between the 2 Sigma lenses..
