I shot the last Venus transit which was very rare. The Mecury transits
aren't that rare, but they aren't common either. A 300mm or larger
lens will do the trick, but telescopes will do a better job. You also
need a suitable solar filter for the lens. Either solar film
(aluminized mylar made specifically for this)
or a metal-coated glass filter.

What does it matter? Rich informed everyone of
an interesting upcoming event. I don't have a photo
of a Mercury transit either. I hope to get one this time.

Here's a few:

Cool, I am probably going to try the old trick of using a telescope to
project the image on a sceen and then photograph that.

That'll work. Just watch out that if you are using a complex eyepiece
(one that has lenses that are cemented together) you don't leave it
projecting the image too long as the cement can burn up.

I have done this a lot with sun spots and have yet to loose an eyepiece
so I should be fine.

The timing it pretty good since we will be seeing it in the morning
which is when it tends to be clear around here.
