The Lens you have owned the longest and still do.

In the summer of my junior year in High School I bought a 1946 135 WF Ektar and a 90 Angulon. Still got them.

My oldest lens I still use is a Leica collapsable 50 mm Summicron I got with my virgin Leica M3 in 1962 !

My first LF lens that I owned was a 8-1/2" Ilex Paragon, and I still have and use it.

First LF lens was a 250mm Wide Field Ektar, 1996. Yeah, I started with 8x10, making contact prints. Spoiled me forever.

An uncoated, mint 162mm Wollensak Velostigmat Series II in a Rapax. A lovely lens.

[Steve Barber]

300mm f5.6 Rodenstock Sironar-N that I bought from Sally Mann, I think in 2003. It was the lens she used for the pictures that were published in "Immediate Family".

[Bill_1856]

90mm Angulon gifted to me in 1953 in a recessed board for my Graphic View II.

A Carl Zeiss Jena Goerz Dagor, 21 cm., purcased Spring 1966 with my 4 X 5 Sinar Norma (see that thread),

Uh, a 50mm f/1.4 AF-D lens for my Nikon. LF-wise, a Schneider APO 150mm f/5.6.

I guess I'm showing my age, or lack thereof...

[Mark Sawyer]

Nine-and-a-half-inch Velostigmat Series II in a Studio Shutter. It was my only 8x10 lens for maybe fifteen or twenty years, sharp as a tack and wonderful tonalities. Still one of my favorites, it's on the 8x10 waiting for wet plates right now.
