These two images were made with a Kodak Aero Ektar lens on my Speed Graphic 5×4 large format camera. The lens was designed for aerial photography during WWII and it’s quite a chunk of glass. Here’s a picture of the setup: http://www.simplyoxford.com/equipment/equipment-aero-ektar
I’m still getting to grips with how best to make use of the shallow depth of field you get with this lens but so far I think it’s a good start.
