Sony 24-105mm f/4 G vs Sigma 28-105mm f/2.8: Best Sony Zoom Lens Review

Buy the Sony 24-105mm f/4 G OSS: http://SDP.io/S105G Buy the Sigma 28-105mm f/2.8: http://SDP.io/S10528 Tony Northrup reviews the Sony 24-105mm f/4 G zoom lens against the Sigma 28-105 f/2.8 lens to see which is the ULTIMATE zoom lens! The Sony is cheaper and lighter, and it goes back to 24mm, and that extra wide-angle can be really important. However, the Sigma is sharper and has MUCH better contrast. It's also a full stop faster so it'll gather twice the light and produce cleaner low-light images with more background blur/bokeh/subject separation. 0:00 Introduction 0:11 Speed, range & stabilization 1:13 Handling & weight 2:36 Sharpness 3:10 Contrast & Backlighting 4:18 Summary
