300d - some un-expected good news.

Hi,
I had a little play in the yard with the 300d. No more crashes thankfuly.
Now the good but somewhat puzzling news.
The Lens is meant to focus to 28cm/0.9 foot, this is what I expected and this
is what it says on the lens.
It doesn't - it focuses well under 10cm - possibly as close as 8 but I haven't
measured too accurately.
I'm very happy about this - but why is it so???
Are they all like that?? Is there a munant strain out there.
Eddie,

 

Are you measuring from the front of the lens or from the film plane? Yes, I
know there's no film, so let's say the sensor plane then. I don't know about
the 300D, but the 10D certainly has a mark on top of the camera to indicate
the film plane, which is where most focusing distances are measured from.

I noticed the same thing with mine (assuming you're talking about the
kit lens). I didn't measure the closest focus, but I did measure the
magnification. It's around 0.36x instead of the 0.28x specified on the
Canon's charts, which appears to be better than any other Canon lens,
not including the macros...

Geoff,

Are you talking about the little circle with the line through it beside
the mode dial? I've been wondering what that was. Thanks for the insight

So THAT'S what that little thing is

I kept pressing it but naught happened. Then I realized it was a
naught, and in effect, actually *had* worked.

That's it.

 

I meant from the front of the lens. Even so the distance to the focal plain is
still way less than 28cm.
Eddie,

 

Jeff,
Yes the kit lens. I didn't buy the 10d because I couldn't find a lens I wanted
for it.
I figured I could live with 28cm and use extensions - but getting such a good
macro is a major bonus.
Eddie,
