Leica M240
Leica 75mm f/2.4 Summarit-M

Veiling Flare + Bokeh, Barn Interior (M240)

This series was shot to evaluate bokeh, but the veiling flare is so severe that the series is more interesting to show just how serious the veiling flare issue is with the Leica 75mm f/2.4 Summarit-M. Your author observed flare issues constantly in a wide variety of field usage scenarios; see for example the Mining Camp Bunkhouse and Green Barn series.

Veiling flare, is very diffuse, but covers a wide area of the frame. The flare seen here is disturbing because there was no reason to suspect that it would be a problem; there was no particularly challenging lighting, merely a bright source of cloudy sky (not sun!) outside the frame.
