OK, I have scanned all my images from my first roll and put them on my
site. Here is the URL:

I see what you meant about the vignetting. With my hoods on like yours,
I got just the tiniest rounding of the corners. I actually needed
magnification to verify it, even on slides with bright blue skies. The
slides are sharp, no doubt about that. My last slides pushed one stop
looked fine. I see the easy hand held shooting along with push
processing as making MF shooting more enjoyable, at least for me.

Some show vignetting in the left corners, some show vignetting in the
top corners, and some show vignetting in all four corners.

The lens shades must be moving ?

The hoods were extended and left that way during the entire shoot and not
touched in any way. My only conclusion from the differing amounts of
vignetting is it must be due to focus and/or fstop.

They are pretty cheaply made ($4.99 each) and not very ridgid so they
don't always hold their shape very well. In fact the two different ones
seems to be slightly different in length when extended.

I just did some checking using a ground glass and the shutter open and it
didn't matter if the hood was under the UV filter or over it. I saw the
vignetting either way. I also just tried to trim some of the rubber off
to make it shorter and that went very poorly as the permanent bend curves
from being collapsed causes the edges to distort the cup very badly.
Trimming below this made the hood too short.

These hoods were sold under the ProMaster name and were made in Korea. No
other markings were on them.

So does anyone have a specific brand/model of hood that works well? Does
anyone have a preference between metal/plastic fixed, rubber fixed, or
rubber collapsable hoods?

The similarly cheap generic brand of collapsible hoods I got from B&H
show an insignificant amount of vignetting in the extreme tip of the
corners only, 90% less than with your shots. Has anyone checked that
the lenses give full coverage out to the corners without shades or with
just a filter on?
