My math is not off. I assume it’s pure titanium and aluminum, 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
