No help on the CLA in Sweden I'm afraid but indeed that thread seems to be missing in action, this was the OP which I found by a circuitous route:

Anyone come across this before?
Seems to be an issue mostly with my Hasselblad 50mm C (non *T) lens.
See attachments.
Directly into the sun for picture 0166 (though facing down) and 70 degrees to the sun on right for picture 0156.
I have all chrome C lenses for my 500cm Hassy and have not really noticed this with the 80mm, 150mm or 250mm in film or Digital Sensor (CFV16II).
Though having checked some film and digital photos into the sun, the 80mm also does seem to lightly do this but the picture were crap anyway so did not notice this before.
Because of this I bought a 6093 hood and this solved the issue with the 80mm but this did add tons of extra contrast with the 80mm, 150mm and 250mm, which I tend to not like doing as I add this after if I feel like it.
I've never really used the 50mm in favour of the 80mm for most occasions especially as I did not have and could not find a 67mm Hasselblad thread to fit the 6093 hood.
So it languished in the cupboard until I eventually made a 67mm thread adapter with bayonet fitting so I could fit the 6093 hood to the 50mm, which at least fits.
But does not seem to fix the flare? at all (in any direction with bright sunlight) if that's what it is?
Incidentally in order for me to fit the 67mm filter thread I made I removed the original filter holder thread that came with the lens.
Could this be the issue?
Anyone come across this issue and a fix?
Should I get a 67mm UV filter to fit the lens so I can keep using my DIY bayonet mount?
Help would be greatly appreciated.
