[LargeFormat] Gundlach 4x5 Korona Anast. f6.3 Series 6x

[Clive Warren]

Have been finding some rather interesting lenses recently. This one 
is a Gundlach 4x5 Korona Anast. f6.3 Series 6x made in Fairport NY 
rather than the earlier Manhattan versions. This one is interesting 
as it is in a Wollensak Rapax shutter with no synch and is a 
convertible 6 1/4", 8", and 12".

It is a really compact little lens and is a later version of one 
which came with a Korona 4x5 field camera which I also picked up 
recently.

The earlier Manhattan glass (under the Turner-Reich name) did not 
have a good reputation for accuracy of centering when the lens 
elements were ground, but when the factory moved, quality control 
improved.

The lens appears to have a slight coating and the elements are 
unscratched and with no separation problems which the earlier lenses 
suffered from after 40 or so years. Maybe the glue used on the 
elements was changed from the earlier Canadian balsam or perhaps the 
lens is so much younger that any separation problems are many years 
away....

Anyway, has anyone used one of these later Gundlach 4x5 lenses 
mounted in a Rapax shutter? It seems ideal for a field outfit.

Will post some images of the lens on the f32 Discussion Forum when I 
next borrow a digital camera.
