The Taylor, Taylor & Hobson 8 Inch f/4 Ortal is a large-format brass-barrel lens from the British optical maker better known as Cooke. With a 203mm focal length and f/4 maximum aperture, it was intended for plate cameras and studio work typical of its era.

At recent UK auction, hammer prices for the 8 Inch f/4 Ortal have been modest, with two recorded sales in January 2026 both reaching £60 — giving a median and range tightly clustered at that level. These are saleroom wholesale results rather than dealer retail, so what this lens is worth as a finished user or display piece in 2026 can sit higher once cleaning and presentation are factored in. With only two data points the picture is thin, so a single well-preserved example could sell for more if condition and completeness are strong.
