2024 8 2 28 200 S add contrast plus Sigma 1 4x TC on an S5iiX

The lens fits on the TC but the TC and lens rear element bump at around 85mm and it looks to me like it is the lens grass then bumps, not just the element supports. Be careful if you try the 1.4 with this 28-200, keep the zoom between 100 and 200 mm and you should be fine.
