11 August 1999 eclipse. Partial eclipse, before maximum, at a non-totality
f 1:32, 1/2000 s, Fuji Superia 400. A Rowt Skylight 1A filter was on the lens and it might have degraded the image too. In other words, the lens alone can't be worse than what you see. Note that the clouds, even those very close to the sun, are visible and distinct. The diaphragm "star" effect is at its peak (f 1:32).
This is a detail scanned directly from the negative.
P.S. Do not compare this image with a proper eclipse shot, done with ND and IR filters, and in which the sun crescent is properly exposed. The exposure here is considerably higher.
