I've been thinking of getting the Canon 100mm macro lens even before the new Macro challenge. I've read about rings and couplers to do really close up shots, but I wouldn't know where to begin to get a working set of add-ons for macro work or what to do with them if I had them.
Could I connect my 50/1.4 to the 100 to get even closer than 1:1? What rings/couplers would you suggest?
Any macro hardware/shooting advice appreciated.
Thanks,
Ara

Yes, I use the 50mm f/1.4 with the 100mm macro; you need a 58mm to 58mm macro coupling ring and you're set to go. The subject distance will be quite short.

Hey Kirbin, how close do you get with the coupler & the 50mm? I still have eyt to take a good shot.

An inch or two is about right. Remember that the DoF is going to be very thin. Try this:
- Set the (reverse-mounted)50mm lens at infinity focus
- Start with your macro lens set to infinity as well (manual focus)
- Use a very small, well-lit test subject
- Start with the front element about 1 inch from the subject, and move back slowly until you get focus.
- Shorten the focus distance on the macro lens in increments, and do the same thing, you'll get the feel for how close you need to be.
With this combination, you are never more than 2 inches from your subject, even at "infinity" focus.

Should I not bother with extension tubes? What does the combination of lenses get you in terms of magnification?

Here's a quick overview of what you can expect with various combinations; please note the magnification smay be overstated by about 5-7%, but they are all uniformly so; it was a result of the measurement method.

Dude! that's great. I really appreciate the chart. I've been wanting to get something slightly over 1:1. Extension tubes will likely do the trick.

Wow! Thanks! Are all tubes and converters the same, or do you have any favorites?

The 12mm tube is a Canon, the 25mm is a Kenko. The Kenko is a little less "soliid, but still has metal mounts and works fine, I'd buy Kenko again.
The 2.0x converter is a Canon (the 2.0x II). That's why I always use that with at least the 2mm tube; it doesn't fit the 100mm macro lens otherwise.
I also occasionally use a Tamron 1.4x converter that actually performs very well, at a bargain price.
