Kodak 12 in. (305mm) f/6.3 Commercial Ektar Acme Synchro BT Bi-Post (72MT) 8x10 Lens Review

The Kodak 12 inch (305mm) f/6.3 Commercial Ektar is a classic large-format lens designed for 8x10 view cameras, mounted on an Acme Synchro BT Bi-Post shutter. This vintage optic hails from Kodak's Commercial Ektar line, which was known for delivering sharp images with excellent contrast for commercial and product photography. The 305mm focal length provides a normal to slightly wide perspective on 8x10 film, making it versatile for architectural, landscape, and studio work.

Available as a used item in excellent condition from KEH, this lens represents an affordable entry point into large-format photography for those already invested in an 8x10 system. The f/6.3 maximum aperture is typical for lenses of this vintage and format, though it requires careful focus and adequate lighting. The Acme shutter is mechanical and straightforward, though potential buyers should verify shutter speed accuracy as these older shutters may require service. At the MSRP of $543, it sits in the accessible range for vintage large-format glass, appealing to those seeking proven optics without the premium of modern coatings or more exotic focal lengths.
