Welcome to my channel! In this video, we deeply dive into the Sigma 16mm F1.4 aperture lens for the Sony E-mount system. We have been facing issues with this lens, specifically it is not producing uniform bokeh when the aperture is wide open. So, let’s open up the lens and see what’s gone wrong.
During the teardown, I discovered that a damaged screw hole is affecting the bokeh. Without repairing this screw hole, it’s impossible to fix the bokeh issue. In this video, I guide you through the entire process of opening the Sigma 16mm F1.4 lens, showing all the intricate parts and explaining their functions.
Stay tuned for my next video, where I’ll attempt to repair the damaged screw hole and hopefully restore the lens to its full functionality. This series is perfect for anyone looking to understand their lens better or attempting their own repairs.
