Leica lens cut in half
From Doobybrain: "Leica lenses are technical marvels and should be taken care of respectfully. So when I saw this Leica lens literally sawed in half, my immediate reaction was shock and awe."
From petapixel: "If colleges offered camera equipment anatomy classes, this Leica lens cutaway might be one of the things you’d be examining in the lab. It's a Leica Tri-Elmar-M 28-35-50mm sliced cleanly down the middle, revealing all the glass and pieces inside that go into making the lens."
"These were actually made by Leica students as a graduation project and boxed as a 'cutaway model' of the lens."
"Here’s the same thing done with a Leica 50mm f/1.4 Summilux M ASPH lens":
I'm betting my Orange County correspondent is experiencing heartburn as he views the photos above.
Sorry 'bout that.

Joe Peach:
The Leica 180mm f 3.4 apo telyit was developed as a sat photo lens. Back in the day these critters dropped exposed panatomic-x from low earth orbit to waiting interceptor aircraft.
I attended a Leica seminar where the company disclosed the resolution of this lens (Leica never publishes resolution data) around '76. This was the lens that could resolve license plates in Moscow.
Today's lenses use aspheric elements - but the 180 was an apochromat created with only spherical elements. The cost of the design and manufacturing line were defrayed by the US cold war budget.

Sophisticated camera lenses are almost in the metaphysical realm.
I would love to see the innards of a classified satellite camera lens!
