I think that Zig and Rodolfo are talking about two different lenses.
There have been two 70-210 f4.0 zooms from Canon -- a discontinued
one and a new L lens that was just released.

Thanks for the help. As it turns out, one of my local stores found an
ES-65 in the back of the store. The wrapper looks kind of old, but
the shade itself is brand new.
<p>
A lens/hood chart would still be nice to have for us cheapies who like
to pick up used older lenses......

I had a few problems with my 540EZ; the flash head didn't zoom, and
the exposure just wasn't right. It seems that I hadn't tightened down
the wheel on the flash foot; once I did, it started zooming again and
subsequent rolls were well exposed. There was no obvious sign that it
wasn't working right (except of course for the lack of zooming); I
guess that's just something to add to our "ready to shoot?" checklist.

Colin:
<p>
Guide Number = f stop x flash-to-subject distance
<p>
The "official" GN for the 380 is 100 (in feet, 100 ASA is assumed)
<p>
To check to see what the actual GN is, use 100 speed slide film, and
take some pictures at 10 feet with the flash on full power manual (is
this an option with the 380? I'm not familiar with that flash).
According to the official GN, you would need an f stop of 10 (10 ft x
f10 = 100 GN). Bracket the pictures around f 10. (Don't use any type
of flash modifier, Sto-Fen, Lumiquest, etc; just bare flash). TAKE
NOTES.
<p>
When you get the slides back, see which setting gave the best
exposure. Then plug that fstop into the formula and you'll find the
actual GN for your flash. Of course, ceiling height, nearness of
walls, color of ceiling and walls will all affect the GN.
<p>
TTL flash is a lot easier than messing with GNs and f stops -- I've
recently moved from a Vivitar 283 on Canon FD's to an A2e with a
540EZ, and WOW is flash effortless now. But it's still important to
understand the theory so you know when you have to out-think the
camera.

Anybody know where I can find a chart that lists which lens hood fits which EOS lens?
<p>
Specifically, I'm looking for a lens hood to the original 50 1.8 lens (metal mount, distance scale). According to a comment in the static pages (yes, I checked there already) this lens takes the ES-65 hood; I've located a store with an ES-65 II hood. I assume that these aren't the same, but I can't get to the store to try it myself.
<p>
Please, no guesses -- anybody know for sure?

I just bought the 70 for my mother-in-law (no jokes, please, she's a
great lady). It does have a spot mode, and a flash off setting (as
well as flash-when-needed, flash-always, slow-sync flash, and red-eye
reduction).
<p>
It turns on when you open the cover, which eliminates the need for
another button. The only problem is that if you're holding the pop-up
flash shut by mistake, it won't turn on. It took me awhile to figure
that one out.
<p>
I took a test roll; it's still at the lab so I don't know what the
results actually look like. But it seems like a real handy little
camera; if it had some sort of exposure compensation it would be
perfect.
