Michael, in putting together an assortment of adapters this is one issue I ran into. It's really hard to find any adapter for an E-mount lens to any other mount, since this mount has such as short flange distance. In general, manufacturers assume that people want to maintain infinity focus so they make adapters accordingly. Rarely you'll find an adapter that does not try to maintain correct flange distance for the lens; I've found these for L39 and M42 lenses for instance.
On the plus side, some Chinese manufacturers have been producing oddball adapters that I expect would have limited markets, so there is hope that something might come up one of these days. Check Amazon now and then.
