I saw that too, they even have 2 of these listed (at a ridiculously high price, but expensive items are usual for Foto Henny Hoogeveen, although I wonder who would want an accessory supposed to work with an unknown film format...). They also list an old DSP 104, without the necessary accessories to make it work... what is strange about that film magazine is that 1. the 70mm film magazine for series 6000 is completely different (much more reasonably sized) 2. The rolls do say "for Agfa package print lab" (cannot find any information about what this is) and 3) "Made in Germany by Schneider-Dresden" - I suppose this means Pentacon? Schneider did own Rollei/F&H for a while so this could explain why this accessory even exists. If someone has a large amount of money to spend on that "thing", I'd be curious to have a closer look...
To get back to the main topic.. Has anyone ever had light metering issues with the Hy6? One of the main advantages of Rollei vs the competition is to be able to use the waist level finder and still have accurate metering -- and it usually works without any trouble. Nevertheless, I noticed a few times that when the sun is strong and, I suppose, close to its highest point of the day (right above my head..) the Hy6 seems to over-compensate for the light that goes through the finder, and shows me much too large exposure times (I did not check with the 6008). Switching to an eye-level finder (or closing the viewfinder hood...) solves the problem. Is it a known issue, or something I should have DW repair?
