My opinion of of lenses made by other companies is it's just not all that good as opposed to original manufacturer lenses plain and simple, the quality of those others is not consistent some work ok for the folks that
Use them. Back in the film days I also bought a few of them my thinking was I will save money and it will be ok but the sharpness was just not the same? I have been a Canon user for more than fifty years I feel Canon makes the best lenses for their own products I have never had a bad lens yet period! Yes you pay more for original equipment manufacturer products but it's worth it in the long run. And yes some of photographers get lucky and with Sigma Tamron and others? But in the end of things it's your choice good luck with what ever you decide to do!

I need an opinion on which lens give sharper focus. I have a canon 70D and need a good low light lens. I shoot family gathering and landscapes mostly. I have a canon 40mm f2.8 but need longer reach sometimes. I checked the Tamron at a local camera shop. It seemed to be soft in its sharpness. They do not handle Sigma, some Hogs speak well of Sigma, and many like the Tamron. Any advice is welcomed and needed. Thanks for taking time to advise.
