Indeed. Not all of us are keen to rip far into lenses, armed with glue (fortunately Superglue is low toxicity) - or equipped to deal with problems that arise.
Just to add that the Leitax mounts are totally reversible and readily accept James Lao chips for EXIF, focus confirm, optimal in-body stabilisation and A mode metering on the Alpha 850/900.
I am also of the opinion that you would have much more success selling a Leitax mount lens than a stuck together lens - but whatever floats your boat(!)
Do the Lao chips work with a 35-70 zoom lens? Don`t they have to be programmed fot a specific focal length? I am thinking of mounting a 35-70 Angenieux to my Sony a850.
