Kenko 1.4x with 70-200 f/4 L IS

Did some sample shots.

• All shots were on tripod with mirror lockout

• All shots were from a little over 5 meters

• All shots were taken 3 times to eliminate random problems

• Image center is a little to the right of the aboriginal art. so crop represents side, but not far side of lens.

• The 200mm shots were cropped to pixel size

• the 280mm shots were cropped to match same FoV as 200mm crops, then downsized to same size.

I think samples show clearly the benefit of the 1.4x TC. *
