Having pretty much run out of things to collect, I recently gave into an
impulse and bought a Pen FT on eBay. I lucked out -- the camera is in full
working order (including the meter) and terrific cosmetic condition (except
for a dent on the bottom plate and some "brassing" of the lens anodizing).

I'd never owned a Pen F camera, so I was startled at just how big and heavy
it was! The body is almost as large as an OM body and weighs only about 2
ounces less.

The traditional story is that Olympus developed the M-1 because 35mm cameras
had grown too big, which is no doubt true. But I suspect that the
"plumpness" of the Pen F was also one of Maitani's motivations. It's obvious
the body doesn't have to be much larger to handle full-frame.

If I interpret John Hermanson's site correctly, he has no parts for Pen Fs.
So, other than my buying a junker, does anyone know where I might find an
undented bottom plate?


A 55/1.2 that came attached to a mint OM-1 body I won on eBay. (I think I
paid $200, which definitely counts as a Fang.) Anyhow, the lens is visibly
yellow -- and that includes what you see through the viewfinder. Doesn't
this lens have a reputation for "waxy yellow buildup"?


Although I bought an Infinity Stylus Zoom 80 Wide DLX (love that model
name!) several years ago, I only started using it recently. Though the lens
has just eight elements, it's decent. In 4x6 prints, I can't see any
particular difference between it and the IS-10/20/30 lens.


Silicones are organic (carbon-based) compounds in which some (but not all)
carbon atoms have been replaced with silicon atoms. This substitution is
possible because both carbon and silicon are column IVA elements in the
periodic table. The silicon atoms change the compounds' characteristics,
most notably their viscosity and heat stability.

Silicones were first synthesized by GE, I believe.

Please note the difference between silicon (the element) and silicones (the
compounds). It drives me crazy when someone says they're going to apply a
silicon lubricant. Well, maybe if you live on Mercury...
