Maybe so. It might be 1/5th sec, but not 1/40th.

I just got two good exposures of trees in the sun yesterday and developed.
Exposures look about right , at least on 1/8th & 1/4.
I did one at f/ 11-16 and one at f/22
At 11-16 it's sharp over 4x5" but turns soft pretty quickly after that.
At f/22 it's sharp almost to the corners of 5x7" , on the top corners it is going at about 10mm from the corner.
Oddly ( despite setting the front up carefully to be centred to the format ) the lower corners look sharp, although there is foreground grass coming towards the camera here - maybe the field curvature is nulled.
Probably worth another shot later.

When I get chance I'll show some small pics either printed or digi scanned/reversed.
