Hi Dirk, I wrote about using an adapter in Issue 16 of Club Rollei User: http://rollei.org.uk/2010/01/club-rollei-user-issue-16/ There is a problem with using a chip – it needs to be situated where the stop-down pin is on the QBM lenses. Hence a manufactured one does not seem to be on the market. I have thought about Aralditeing a chip at the bottom of the mount but have not got around to it yet. You have to stop down the lens manually anyway so this would not necessarily be a problem...

Can you tell which adapter you haveß I heard that most adapters do not work with the 1,8 50 Planar as the back of the lens goes too far into the adapter.

Without, you're on your own for the focusing. With, you get the little red box to confirm where you're in focus. The chip is available on its own if needed. I have one without and it works quite well, I have tried it with the 55/1.4, 50/1.8, 85/2.8 and some non-Rollei 28-70 macro lens (don't remember the brand). They all worked fine on my 5d and 1d. No exposure problem. When I tried it on the 450d of a friend of mine, it seems it didn't like the all-metal adapter and started to blink ... I have been told as well that some lenses may hit the mirror but it seems I have none of them. So your mileage may vary.

I just bought an adapter to use on Olympus FourThirds, but I did not yet receive it to test it. Adaption should also work to Canon, but some adapters allow no infinity focusing while I also read that some lenses got so deep back at infinity that the mirror of the Canon would touch the back of the lens. Any reports of own experience and also recommendations for adapters and best camera bodies combinations to be used are appreciated. Yes I know, finally this is then no more a Rolleiflex. But maybe using a Carl Zeiss Rollei 1.4/85 at a Canon will finally let us continue to use some good Rollei staff! ;-) Regards Dirk --- Rollei List - Post to rollei_list@xxxxxxxxxxxxx - Subscribe at rollei_list-request@xxxxxxxxxxxxx with 'subscribe' in the subject field OR by logging into www.freelists.org <//www.freelists.org> - Unsubscribe at rollei_list-request@xxxxxxxxxxxxx with 'unsubscribe' in the subject field OR by logging into www.freelists.org <//www.freelists.org> - Online, searchable archives are available at //www.freelists.org/archives/rollei_list
