While I am waiting for my X1Dll, I was wondering how well the XH adapter works in terms of IQ? I have the HCD 28 and 35-90mm lenses. Also, the HC 50mmll. These are older lenses and I know autofocus is an issue, but I am much more interested in IQ. The market for these H lenses seems to be poor (certainly in terms of price) and I also need to keep one or two lenses for my existing H6 camera. Any and all thoughts would be appreciated.
