Q: 4. will this fit a canon xa20?

A: Sorry, but the Canon XA20's lens is not removable so there is no way to mount this Kowa lens. Since 25mm is very telephoto on the XA20's 1/2.84 HD CMOS Sensor, you might consider this tele converter that you mount on the front of the XA20's permanent lens. Canon TL-H58 Tele-Converter Lens (1.5x) B&H # CATLH58. Of course, this all depends on what you are planning to do.

Q: 5. Will it work on the Canon C200?

A: It could work, though there's no way to view a desqueezed image on the C200, so you'd have to use an external monitor with an anamorphic desqueeze mode. You may also have to slightly crop in to avoid vignetting.

A: The image circle of the Sirui 24mm f/2.8 Anamorphic 1.33x Lens (MFT Mount) (B&H# SI24AM43ML) is sufficient to cover a micro four thirds sensor.
