Sinar Horseman/Sinar 4X5 Lens Board, Black, 35 Hole (140x140mm) Review

This is a used Sinar lens board designed to fit Horseman and Sinar 4x5 large format cameras. It features a 35mm diameter hole in the center and measures 140x140mm, which is the standard size for these camera systems. The black finish helps reduce internal reflections. Lens boards like this one are essential accessories for large format photographers who want to mount different lenses to their view cameras. The 35mm hole accommodates a range of shutters and lens barrels common in large format photography. At $39, this used board from KEH (graded as Excellent condition) offers a cost-effective way to expand lens mounting options without paying new prices. These boards are straightforward mechanical components with no electronics or moving parts, so condition matters primarily for cosmetic reasons and ensuring a secure fit in the camera's front standard.
