I have taken 2 pictures, one at f8 and the other at f16 with the
following
lenses:

Canon EFs 18-55 f4,5-5,6 ("kit" lens modified to fit on a 10D)
Canon EF 50mm f1,8
Canon EF 24-85 f3,5-4,5
Canon EF 35-80 f4-5,6
Canon EF 24-70 f2,8 L

So we have 4 zooms, 3 plastic cheapie lenses, one middle of the road
zoom
and a primo pro lens. The "kit" lens is one of the early ones which
came
with my Drebel, the newer ones are said to be better. I tried to put
all
lenses at 50mm and not move the tripod but there are still some slight
changes from one lens to the other.

The pictures are at http://www.pbase.com/jeandr/50mm_test

Now which is which?

PS These are all TIFF files and at about 4Mb each so a broadband
connection
is better for download. There is no EXIF to make sure no one cheats
(unless
I missed something embedded in the files which is quite possible)

Autofocus, or manually focused, with good eyesight? If autofocus,
forget comparisons.

Autofocus, good eyesight, 3 shots took the one that looked the best to my
good eyes with reading glasses. At that distance, I would think autofocus
would not be an issue.

Does that mean autofocus is erratic or never accurate?
-Rich

neither. autofocus is accurate - at least on Canons {:-), but with a
subject containing some depth, like these test shots, with large bushes
in the foreground, an oblique angle on the buildings, and a seven-point
focus system, who knows where the focus was. I wager most people looked
at the roof skyline or chimney, and I bet that wasn't the point of
focus. All this means the shots were demonstrating dof and not much
else.

Most of the "canonites" have never used anything but a canon so have NO idea
what else is out there. Many of them started with a Canon autofocus 35mm
and have never used anything else.

And could you have blown the highlights out any more? Even the roof of the
house is blown to oblivion!

If you want to post a "lens test", post some full rez crops of each one.

You're assuming none of the lenses front or back focus.

Why? Maybe he should make 5 Shots, and select the worst, but if I buy an
autofocus lense, i want the autofocus to work properly.

I started out with a Canon TL, and then moved to an FTb. My first digital
SLR was a Drebel and I was dissapointed with it's manual focusing abilities
just as I am with my current DSLR (10D) so I rely on the autofocus. I works
most of the time especially if only one focus point is selected. With
action shots, there is no way I could do better manually, AI servo mode is a
shot saver.

40% you got two right. 1 and 3. Now if anyone cares about picking the two
remaining choices (#4 was given in a previous post).
