Thread at the front of a summilux 35 pre asph?

[SYD_TRIBE]

Excuse my ignorance.

I've recently acquired a lux 35mm s/n 3474710 and 12504 hood which clicks on the front.

Question - what is the thread at the front of the lens for?

I read online that this little beauty doesn't take filters without the 12504 hood, so whats the purpose of the thread?

Mine has concentric rings but no thread. Unless you have some rare modified front end on your lens, only series vii filters can be used with the 12504 hood (it screws apart to hold the filter). Hope this helped.

...only series vii filters can be used with the 12504 hood...

Or 49mm filters mounted upside down.
