A CAD rendering of the upcoming Eckhardt New Dallmeyer 3B
Eckhardt Optics of White Bear Lake, Minnesota, is taking orders in advance for its upcoming replica of the Dallmeyer 3B. The 3B was a variant of the Petzval intended for cabinet portraits, with a focal length of 292mm (11.5in). (For large format cameras, if that doesn't sound familiar.)
A sample made with the prototype of the new lens on whole plate
Eckhardt says its replica will have "the exact functionality of the original," which means brass and aluminum construction and Waterhouse stops, and "glass which closely replicates that found in the originals." I presume this means the lens will be uncoated (a good thing, to aficionados).
The originals, which Eckhardt rightly calls "rare and costly," were made in London at about the time of the American Civil War. They are especially valued today by wet collodion enthusiasts. Pre-orders end on March 21st at 5 pm CST. There are more samples at collodionbastards.org.
