Thanks for the info Phil - 44mm - Clear skies tomorrow night are forecast, so I am going to work the lens from f2 and up to see what happens.
The ST8300 has 17.5mm backfocus, and the FW8300 has 20mm - so thats 37.5mm. The Canon lens adapter easily adds probably 5mm or so, I have not measured it (but will), so that puts it very close, assuming a delta of perhaps 1.5-2mm is not critical - it probably is at f1.2.

cheers
Martin
