I have noticed this K-24 lens for a long time but till now I did'nt see much use for it.
Interesting piece of glass though...with a yellow dot on the front ring. They come without as well. Lenses were made by Kodak, Rochester and were produced by thousands during WW II.

However things have changed since I own a Pacemaker SG. The possibility to use barrel lenses (built in focal plane shutter) broadened the choice of lenses.Through the internet I came in contact with a US Photo journalist David Burnett.We first met in october 2005 in Amsterdam.
After seeing his images I really became interested. Using the lens wide open f2.5 gave a very shallow depth of field and an irresistible Bokeh.

Discussing several possibilities to mount the lens we have chosen for David's configuration which we'll try to describe in here...



During our conversation we talked different lenses like the Apo Lanthar/Voigtlander and the Ernostar 165mm f1.8. and of course the Aero!
David is interested in a Ernostar 165mm f1.8, if you have any tips or links, please let us know.
On weight and handling: David's vision: I had to have the rangefinder on the camera synched to the lens (a 7" Aero Ektar f/2.5, built in 1943) in order to be able to shoot 'on the fly,' that is, to make a picture without having to compose and focus on the groundglass. When people move you need to be able to refocus quickly. When I get a frame that I like, it helps make the annoying bits go away. But the system is not for the faint hearted. Schlepping is the word which most comes to mind when using a big camera like this. You are inherently a little less nimble than the digital shooters, but when you press the cable release, and the shutter raps through the camera, you can almost SEE what you're getting.

Well enough for now, let's shoot some Polaroids...I want to hear that shutter rapping!
