A question about the new M 240 Titan

I read on the Leica site, that the new titan version of the 28summicron and 50 summicron asph, that they are made out of aluminium with an " eloxiertes " titanium layer.

 

I thought in the former lenses, of the M6 titan and the M 6 TTL titan were made of brass + titanium eloxierung.

 

Anyone has an idea why the changed to aluminium?

Less weight?

The Leica Q3 is available for pre-order at B&H Photo Video and Adorama

Hello Everybody,

 

"Eloxiert" is German for "anodized". Anodizing is a process for black coating aluminium lenses which has been used by Leitz/Leica for over 50 years.

 

Best Regards,

First, there is no "Titan" Leica cameras. There are Titanium models, I believe.

 

Secondly, titanium is plating and not anodizing.

Less weight?

Would be possible, but why didn't they make the first ones like the black, less weight, but with brass lenses. I thought it had something to do with the process of "titanisierung" that it wasn't possible with aluminium, or has something changed? ( or was this with chrome ?) .
