I recently bought a new Tamron 24-70 f2.8, I have a canon 750D, when I'm using the view finder the focusing is extremely quick, however when I flick it to live view it literally takes 2-3 seconds to focus.
When using my 50mm ef f1.8 lens I have zero issues with the live view.
Could this be because the tamron is made for professional cameras or?
Thanks for your time, Phil 🙂
