From an article in Photo District News:
It’s common for some photographers to hold on to one or two pieces of prized gear, but
Berliner, who serves as executive director of the
Penumbra Foundation, has what can only be described as a treasure trove: a collection of approximately 1,500 lenses dating back to the 1840s in every formula and format. “I also have cameras in every format from half frame to 20×24 inches.” (And you thought you had gear acquisition syndrome!)
Berliner is no mere acquirer. He modifies and shoots the gear too. “I like to modify cameras so they suit my needs and aging eyes,” he says. Asked to identify a few favorites, he singles out the Plaubel Makiflex. “I like the square format, Rolleiflex, Hasselblad, etc., but I like a larger negative. So, I found this camera which makes a 9×9 cm square negative on 4×5 film. It also takes
medium-format120 roll film backs but that defeats the purpose. The camera is mounted with the 4×5 sheet film back, [which is] rare to find.”
Berliner modified the Makiflex by attaching an adjustable lens clamp, enabling him to swap out lenses. “This camera has a focal plane shutter so barrel lenses without shutters can be used. The lens mounted is a Dallmeyer 1B Long Petzval Portrait lens, circa 1870s. I also modified an Arca Swiss chimney finder to replace the waist level finder, which is much easier to use.”
