I would expect quite a dust problem using these in the field.

Facinating (but painful to look at).

I am off to buy a good saw.

Also there would be a greater risk of flare I guess.

Mechanical beauty. A modern plastic zoom might look a bit different than tri-elmar.

Sadly we can't saw-in women the same way to see how their inner workings are :-)

Boris, some things are best left to the imagination or even not imagined at all; just enjoy the package and don´t enquire too closely.

I thought you meant the other way. Some LF lenses can be used as aeither or both of the front and back groups. Perhaps something that might catch on dslr users?

The perfect lens for crop sensor cameras.

That's at the Museum of Science and Industry in Chicago.

Very interesting seeing the internal structure. It made my eyes pop. Good article, too. Thanks.
