I've seen posts both ways [and I'm not sure I'll believe any answers to this
post either... :)], but can anyone say for sure if the canon 100-400 with the
canon 1.4 II extender will auto-focus on a canon 20D body?  [And is it limited
to the center spot?]

I did a small trial for what I hoped would be a reasonable demonstration
of the cumulative effect of reopening and saving images as jpegs on
image degradation - by superimposing the compressed image as a 50%
transparency over an inverted colour image of the original.  Do it with

When using an incident-light meter, holding it at or near the subject and
aiming the meter's light-sensitive cell back toward the camera.
I notice a difference when shooting at 10 ft and when shooting at 20 ft.
Say when shooting at 10 ft I need to give it f8  but when taking the ...

Im looking to buy a Canon 350D but I have no idea as to what the lens
sizes mean and what zoom range they relate to.
For example, one of the lenses that comes with the 350D is 18-55mm and
there is also a 55-200mm.

I'm thinking of getting the Sony P200 or W7. They both can take a 1 Gig
Memory Stick Pro.
They are about the same price. Is one better than the other?

It seems like the EXIF data from a bunch of the photos I took yesterday
is being lost in the transition from RSE to Photoshop.  Not a major
disaster, but a curiosity as this has never happened to me.  Has anyone
else had a similar problem, and if so, was it Photoshop or RSE?  Camera

Suddenly the flash of my HP 850 doesn't work! :(
Somebody have never tried to dismantle the photo camera and can help
me?
I have problems to open the part near viewfinder. It is hard and I fear

I have a Canon A75 and everytime I download my pictures from my camera to my
computer it would only download the JPEGS. I recently had to reinstall my
operating system. After I did this I noticed that for every folder
containing my pictures there is an added file called ZBThumbnail ...

I had an S20 that was great, but after two years it stopped snapping.
Canon said it would cost more to fix than to replace. I upgraded to a
G3, and was very happy until 2.5 years later the screen crapped out.
While I'm ready to upgrade to a DSLR anyway, does Canon deserve a third

... you'll see that Mr. Briot says that he gets a *bigger* dynamic
range from digital (Canon 1DsII) than he does from film (4x5).

I am looking for a combination camera/laptop bag that can hold a 15" lap
top, a 20D, and a couple of lenses, plus battery charger for 20D, and
some additional electronic gadgets (cell phone, flash drive, etc.). Must

I need to take a lot of motorcycle photos for an event I will be involved
with. I've taken a bunch of motorcycle photos in the past, but have never
used a backdrop. I have usually been able to find a bit of shrubery etc, to
make a nice natural backdrop, but this location doesn't ...

I am in need of a software download. Seems the company is out of
business. Can any one help out here?  Thanks in advance.  Chuck

This is my second year taking pictures at Coney Island's annual Mermaid
Parade. This parade celebrates the opening of the summer season. I like
this parade, as most of the participants dress up in costume. However, this
year it was more crowded, and I don't think I was able to get ...
