This page shows how the 1.4X extender performs on the demanding mosaic target.
Note that the two zooms are being used as reference lenses by themselves without the 1.4X extender, the goal being to see how well the 135/2L + 1.4X can perform against the zooms.
Reproduction ratio and positioning are not exactly the same between the combinations tested, but they are plenty close for comparison of relative quality; we’re looking here for contrast and consistency throughout the frame.
- Canon 135mm f/2L + Extender III 1.4X (nominal 190mm).
- Canon 70-200mm f/4L IS @ 190mm (lens by itself, NOT using extender)
- Canon 70-200mm f/2.8L IS II @ 190mm (lens by itself, NOT using extender)
