My math is not off. I assume it’s pure titanium and reached the conclusion of impossibility. So I said it must be alloy.
Besides, in a typical Summilux lens, there are about no more 65-70% weight is from glass. So that 245 gram v.s. 22 gram distribution is definitely off, therefore it must be alloy
Assuming pure titanium would be pretty wild considering its high reactivity with air. Also, I said your density figure is off, not your math. They aren’t using pure Al or pure Ti.
The website had already disclosed the use of alloys for both versions. 7075 for the Al version.
If I had to make an educated guess on the Ti alloy used it would be Ti-6Al-4V as that is the most commonly used alloy for that type of application, but that is speculation on my part. The other option would be some kind of Ti plating as someone else already speculated.
But as you said, that would still require the vast majority of the weight to be glass. Certainly possible but pretty impossible to speculate beyond that.
