That's got a 'war of the worlds' vibe. Neat! Do you know what it's meant to contain?

Zeiss 25/2.8 + R72
Well, I got a new lens. It was on the list of lenses that are deemed good IR lenses. So, I took a chance and bought one. Plus, I wanted a wider lens.
Tested at my favorite place. Went from f5.6 to f22. Used the 850nm filter to really stress test for hot spots. Never found a spot, even at f22!

Now, to go out and really use it!
Looking good, Jon! That was my main wide angle lens from about 1994-2021. I had to retire mine as it stopped focusing. Otherwise, I'd still be using it.
