Thread for Componon-S 240 - 66mm???

[Tom Stanworth]

I have been failing miserably to get the thread size for mounting on my enlarger lens panel. I saw a 66mm on the internet on a website selling panels. Sounds weird. Should it be 67mm?

Can anyone clear this up for me?

Tom,

I measured my 240mm-F 5.6 Companon S by laying a mm guage across the lens mount and I came up with 65 mm. I may not have been as accurate as a micrometer measurement though. So very likely the numbers you mentioned are accurate.
