Yes, that's the case of the 28-135 IS in the wide end. You can see the

Hi Tom,
As a person who uses the 420EX with EOS30 for 75% of the shots (as
flash, not just AF assist), I'll share some of my experience with you.

Let's say I want to use flash as the primary light source. But I also want
to control the aperture. So I set the camera to M mode and set the shutter
to 1/125 and the aperture to the desired opening. Question: how do I know

I recently picked up a 420EX and I am testing it to see if I should keep it. It seems

Without any accessories, a lens can be set to focus between its

Thanks for the information Lars, Tom, and Tony. I will have to think
carefully as I use mainly zoom lenses and note your comments on zoom +
extension. I had hoped for more postive comments on the tubes so will
consider if it might be better to leave them and see if a cheap 2nd hand

I have a few question too.
1) With a tube can a lens (100/2) still be focused throughout it's entire range?
2) Same question but with a 500D?

There is an article where the author did some tests and found that 2-element diopter
lenses produce better quality images than do extension tubes.

Neil,
That's an impressive list and lesson in history. Thanks for the info. I
think what Julian was getting at (and keep in mind it's all in fun) was that
we already have things to handle focus and exposure with idiot modes to
boot. To my mind, focus, exposure and composition are the three elem

Tim,
extension tubes are a decent, inexpensive way to extent
your photography towards close-up and macro. No additional
glass, and automatic aperture and auto-focus are retained.
Extention tubes are a bit slower to use because of the
additional mounting and unmounting required.

Tim,
You didn't mention the brand. Are those Canon or Tamron?
There seem to be no difference between the two though, except (maybe) for
construction sturdiness.
Your 'L' quality remains. Just don't go too far stoping down, since the effect
of diffraction increases.
Regards,
Gerard.
