I have the XL1s camera with the lens adapter and have used it with the tamron 400 lens,wirks fine but everything is manual control .It is large and heavy but the lens has tripod mount.
My question is can the XLs1 lens be fitted to a canon digital camera like the 5D,is there an adapter for that .
Also does this camera retain is money value,mine has 2hours on it

Check used camcorder sales venues, Craig's List, E-bay to see the extent to which XL1s retain value now that they are manufacturer discontinued.

To my knowledge no one has offered a mount adapter to put a XL1s lens on a non-XL series camcorder, especially a 35mm size body such as the 5D.

The value of doing this is highly questionable. The XL series lenses are designed for use on a camcorder with a nominal 1/3" image sensor, not a 35 mm still film frame that is nominally 7.2x wider. Performance with a larger image sensor would see significant fall-off of image quality outside design sensor size region as well as major vignetting.

Note that the 1/3" is not the actual physical size of the XL1s sensor, but is a relative term based on the size designations used for the imaging tubes in early television cameras.

thanks for the info ,you're right about using the video lens on a 5D,its just that the xl1s camera sits alot and it would be nice to get some extra use of the lens from the xl1s ,it is a good lens
