Interesting information just came to me when I read my Profisix light meter manual.
In the section regarding accessories and their usage, there was a note regarding the use of Lunasix 3 attachments.
I didn't realise that there were different attachments for the Lunasix compared to the rest of the range.
An example, and I quote from my handbook.:-
You are using the Tele attachment of the Lunasix 3 on your Profisix, set for the 7.5 degree measuring angle; you would have to set the scale value on the Lunasix 3 to the green index. To consider the correction value on the Profisix, set the white index (15) at "(+)3" on the EV modification scale (13).
Unquote:-
So it appears that there are different Tele attachments, with what appears to be identical external looks. I have never realised that the Tele attachment came in anything other than the one version. Something I didn't know.
I have used a Tele attachment on my Profisix, I did like it but I have the spot attachment which takes 1, 5 & 10 degree readings. One day when one pops up at a reasonable price I may be enticed.
