Geoffrey Berliner is the Executive Director of the Penumbra Foundation, a non-profit photo arts organization in New York City. He has also been an avid collector of historical camera lenses for 15 years. Pop Photo recently paid a visit to the basement where Berliner stores his massive collection of rare glass. In the video above, Berliner briefly talks about his passion and offers us a glimpse into his unique stash.

Started out doing photography at the age of 6 using an uncle's old 1940 kodak brownie box camera. At 15 years of age, I decided to buy my very own 1975 Praktica SLR camera. I now shoot with a Nikon D850. I do unpaid TFP and commercial paid work.
