I have a 60D with two lenses, 85mm 1.8 and 28-138mm. I really what to let go of the 28-138mm and get something better and faster. I have been looking a quite a few lenses and just can’t decide. I shoot indoor and outdoor portraits as well as low light concerts mostly. Do I sacrifice zoom and IS for image quality and speed. Im looking to spend $500 to $600.
This is what I was looking at:
Sigma 17-50 OS
Tamron 17-50 VC
Sigma 17-70mm f/2.8-4 Macro OS
Sigma 30 1.4
Canon 28 1.8
