Questions
Why is the rear element yellow?
The Aero Ektar uses thoriated glass elements that yellow over time due to low-level radiation from the thorium; this is a known characteristic rather than a fault and can be lightened by extended exposure to UV light.
What camera does the Aero Ektar fit?
It was originally fitted to military aerial cameras, and today it is most commonly adapted by users to 4x5 Speed Graphic and similar press-type cameras for ground-based photography.
