An attempt to illustrate any effects that the Canon WD-H58W wide angle adaptor has on the image quality of the Canon XA 10 camera.
The White Balance was locked down for all shots, so the observed color shift is likely due to the WA lens.
Using screen grabs and enlarging in Photoshop does reveal some slight image softness due to the WA.
The queston: Can you just leave the WA adapter on the camera and pay no significant penalty??
Maybe you can :)
