Sinar 90mm f/6.8 Sinaron-W MC DB Mount Sinar Lens Review

The Sinar 90mm f/6.8 Sinaron-W MC is a wide-angle lens designed for large format 4x5 cameras with the Sinar DB mount system. At 90mm, it offers a moderately wide field of view on 4x5 film, useful for architecture, interiors, and landscape work where you need more room in the frame without extreme distortion. The f/6.8 maximum aperture is typical for lenses in this focal length and format, providing adequate light gathering while keeping size and weight manageable on a view camera.

This is a multicoated (MC) optic from Sinar's Sinaron-W line, which historically aimed to balance optical quality with affordability for large format shooters. At $173 in excellent-plus used condition with board and caps, it sits in the accessible tier of large format glass. It's a practical choice for anyone building out a Sinar system or looking for a workhorse wide-angle without spending thousands on premium optics.
