I have the FULL spectrum mod (both filters removed) on my 1000D which I use for spectroscopy.
The loss of focus when using standard camera lens is minor BUT with EF lens the astronomik MC clip in filter can be used to correct.
Unless you really need to access the UV below 400nm and the NIR above 700nm you can safely leave the front ant-alias/ dust shake filter in the camera.
