[rollei_list] Re: Rollei taking and viewing lens alignment

Is there evidence of impact on the lens standard? The lenses have to be absolutely parallel mounts on the lens board. This is a very difficult repair requiring specialized training and tools, so I hope you sent it to a good repair shop.

The parallax compensation moves a mask in the viewfinder to approximate the effect of close focusing.

Hi Folks
I finally shipped out my FX to get the rewind-tripping-shutter issue looked at and also to re-calibrate the focussing. The repair house has come back quickly to point out that in fact the camera has at some stage been a victim of gravity (my humour...) and is quite a bit out of alignment. They are in Germany and are well respected so I am quite happy to give them the go ahead with the repairs. One thing I'm now curious about though is that I had always noticed that the taking and viewing lenses were not exactly parallel - they appeared to be aligned ever so slightly 'into' each other. I simply thought this was to do with parallax minimisation but am now wondering that is not normal and in fact was a gross manifestation of the alignment probs. In short should the lens pair be exacty parallel?
I might add I never did any 'brick-wall' tests (taking a photo of, that is...) but had been fairly happy apart from wide open focussing.
rgds to all
