    150mm lens for 4x5 inch camera

    Is that like a 50mm standard lens in 35mm photography ?

    Yes, but anything between 135 and 180 would be considered "normal", in the same way a 35 mm lens could be a wide normal and say, a 60 mm lens would be considered a long normal in 35mm photography.

    Some addition to Jerevan's answer:
    A Tessar will give you a smaller image-circle than the more expensive lenses like the Sironar, important to know if you want to use shifts with the TC.

    The best way to calculate a 'normal' focal length for any film format is to measure the diagonal of the film plane. The diagonal divides the film into two equal triangles.
