I suppose all that stuff could be added, but you're probably right that it won't happen. On the other hand, I do have a 0.42X convertor that fits on the front of the lens. It does produce some pretty horrific distortion around the edges, and adds a turquoise colour cast so it only usable for "arty" images on my MZ-S. With a *ist-D however only the middle area would be used, and the camera could adjust the white balance. A 50mm lense would thereby become a 33mm lens (50*1.53*0.42) and a 28mm becomes an 18mm. I was going to put it on ebay, but I might wait until I get a *ist-D to see if it's useful.

You'd need more than that - you'd also need something to stop a K/M lens down to the right aperture; the actuating lever on the body only moves to the 'A' lens position, which isn't far enough to fully stop down a K/M lens. And, of course, you would only want to increase the travel for a K or M lens; for an A or later lens you'd want to use exactly the travel that the body supplies. (In other words: it isn't going to happen) Good news on the optical front, though; I'm fairly sure the earlier poster who caclulated image distances, etc., got it wrong. A simple concave lens acts as a reverse teleconverter (image magnification factor less than one), but increases the primary-lens-to-image distance. Theres no image inversion, and there's room for the converter. So the optical side, at least, is possible.
