Re: This is not a good test image

Anything will look blurry at 400% crop. But this is a good example to show there's no motion blur, as each thread is ghosting in different directions. Check the bottom of the image, it's pretty sharp. It's a lens issue, not a shutter speed issue.

As Ted pointed out, you misunderstood my example. There was no resampling, and at 400% I would expect to see pixels, like in this 400% crop of a flower bud:

(This is the 100% crop:)

The OP's image has plenty of fibers in it, I'd expect to see  them 1 pixel wide, but they aren't.

Right now I'm leaning toward operator error,, but as I said originally, a 0,6 sec exposure is not the way to test  that.
