Colin, This is one of the reasons that I also like Minolta is the 'retro fit' capabillity, however there are a couple of areas where this practice has changed, the new lenses available for Minolta SLR's i.e. the SSM will only function with the present series of Dynax cameras e.g. the Dynax 7 (the latest Pro Dynax 9 has to be 're-chiped' so to speak) and there is a problem with flashguns the Digital cameras will only work with the latest Flashguns i.e. 5600 HSD, 3600 HSD and 2500 D. these flashes will work on your 800Si but you won't get all the capabillity e.g. ADI pre flash etc. <font color=blue>RonM CRIPN</font color=blue> Everyone has a photographic memory. Some just don't have film.
