Acquired a Kodak Commercial Ektar 10" lens (mfr. 1957) for my Toyo 4X5 view camera and, upon delivery and inspection, two air bubble occlusions are found in the lens elements.
One air bubble occlusion is in the front element; the second air bubble occlusion is in the rear element. The bubbles are about the size of a champagne bubble: Very small, but immediately observable within the composition of the lens glass when viewed looking through the glass from both the rear and front objectives.
1) Will these occlusions affect resolution, contrast, and image quality?
2) How could this lens pass Kodak quality control at the time of manufacture and distribution? I have read that Kodak Ektars are among the finest lenses of their era.
3) Is it common to find minute bubble occlusions in Kodak Commercial Ektars?
Thanks in advance for your comments.
