Are you deliberately trying to provoke a rude comment from Jonathan?  Cheesy

Not a bad idea, actually.  Why not put an easily-cleanable, easily-replaceable optical flat in the lens path?

Cheaper than my solution to the same problem, namely two bodies.   Never change lenses.

If I had a x1 teleconverter (although it wouldn't be a teleconverter at x1) I could leave it on and change lenses and not get dust on the sensor.
Is it possible to put a good quality piece of plain glass in the thinest converter body and leave it on the camera? I am guessing that the focal length must change (bit like bellows?) but by how much? would a 10mm become a 12mm or 30mm?
Is this a brilliant idea  Cheesy  or the start of an urban myth?

Cheers Spike

A 1x converter would move the lens forward and prevent the lens fromfocusing at infinity. Bad idea. Canon did make a DSLR model (one of their very first, before the D30) with a glass window between the lens mount and the mirror box to prevent sensor dust, but it turned out the glass was prone to breaking during lens changes, at which point the user had a much worse problem than a few dust bunnies on the AA filter. Between the cut/puncture injury hazard from the glass splinters and the incidence of glass shards jamming and damaging the mirror mechanism and shutter, the idea was scrapped. And now you know the rest of the story...
