Hi Austin, The loss of functions effectively means that the 6008i (or other 6008 variants) will have the same features as an SLX or 6006/2 ie it will only have shutter speed priority and manual. I believe that if you put an HFT lens on an Integral and try to use for example programmed or aperture priority, a row of dashes appears where the viewfinder shutter/aperture read out is and possible that the camera will not fire. This effectively informs you that the feature is not available. I have not used an HFT lens on my Integral for a long time so cannot remember exactly what happens. Whether such facilities as flash sync on shutter close would work or not I have no idea either. Just have to try such things out. It used to be possible to upgrade an HFT lens to give the necessary information to the camera body so it could use all the 6008 camera functions. I cannot remember if this was a return to factory task or whether it could be done by the local importers. Whether the necessary parts are still available is anybody's guess. Paepke Fototechnik in Germany (see http://www.franke-heidecke.net/ authorised repairers for full details)would probably be able to help if this was to be considered. However, the cost of a secondhand PQ lens now is probably the cost of an upgrade anyway. When I bought my Integral, I thought that all the extra features would be useful. I have found that most of the time I use manual exposure and that in this respect my 6006 and 6002 are quicker to use (I could have saved a fortune but would have always hankered after something better) so an HFT lens is not such a disadvantage. ;-) Regards John =20 -----Original Message----- From: rollei_list-bounce@xxxxxxxxxxxxx [mailto:rollei_list-bounce@xxxxxxxxxxxxx] On Behalf Of Austin Franklin Sent: 20 February 2008 13:31 To: rollei_list@xxxxxxxxxxxxx Subject: [rollei_list] Re: MF SLR lens designations =20 Hi John, Thank you very much for the great explanation. > All lenses can be used on the latest 600X series cameras with some=20 > loss of camera functions. Can you please outline with this loss of camera functions is when using an HFT lense on a 6008 Integral?
