Also with Zoom lens, the extension of the barrel can suck dust into the
internals.
I wonder if Larry has the same dust issue with prime lens?

Looks more like dust internal to the lens to me, especially if you
only get it with moderately stopped down aperature. Is it the same

I tried it with another lens and it’s mostly the same.
Kind of makes me wonder though?
During the year I spent in Iraq my *ist-D didn't accumulate that much
crap on the sensor & I frequently had to change lenses in some really
nasty situations.
What are you doing to that camera?
