A Sonnar Shot A Day

I used to optimize my Fortran programs on the VAX 11/750 by probing the boards with an Oscilloscope.

I was too young to be at MIT, LMI, Symbolics, TI or Xerox to do the same in LISP on the various LispMs and high level assembler (aka C) didn't really need it. But it's funny to look in the open source sources of Medley Interlisp and see programming structures designed to use the Dandelon 1108's specific hardware to optimize memory management in the virtual machine. The VM for PC's available for download fakes those structures in C 😉

A test shot with the Collapsible Nikkor that I opened up yesterday. This lens had severe build-up of oil on the surface behind the aperture, and a lot of deposits on the front element.

"This is what Success looks like" when cleaning a lens. The inner surface- coatings fully intact, and all clean.
Wide-Open.

Exquisite. I am presuming this would be the same as the regular Nikkor 50/2 but built like the Zeiss collapsible?

Yes- the first couple of thousand if the 5cm F2 Nikkors were collapsible mount, min focus of ~3.5ft. The rigid- the 5008 series go to 18".
 
I enjoy my rigid mount Nikkor and despite my collapsible lens fetish I doubt I'll go looking for one (though if one fell in my lap... 😉 ). Having the 50/1.4 on S & 50/2 on LTM this reminds me that in most ways at that time unless you REALLY needed the extra speed, the 50/2 was the better lens.

I do have a struggle between the Zeiss collapsible and the Nikkor though because the Nikkor being coated does have a different look. Neither is inherently better or worse, but obviously different.

As rewarding as an exquisite and complex do-loop working perfectly first shot.
 
This fellow has one of these in this area. There is another. It is all electric. He got 35 miles with it (Astoria to Clatskanie), charged it and drove home. We get ~100" of rain a year, and this thing has no windows. He tells me the back seat gets some spray. He does not ride there, his wife does. The company is bankrupt. I wonder why? It was fun hearing him defend this thing. His wife made herself absent.

The good news is, yes there is good news, that black rack on the right can carry a golf bag.

There's this Rooster statue down by the university. Really a nice bit of work, The last one I wanted to get the morning sun in the east into the frame (rooster, morning, crowing, etc). Doesn't really work but it's an interesting failure so unlike several other images in the set, I'll post it anyway 🙂 32.jpg33.jpg34.jpg
