Hi there,
as you can see in my sig I have a 5D + 100mm F2.8 IS Macro.
I didn't had a macro lens before, so I need to learn a lot.
A few days ago I used a 40D with my macro lens and I was blown away with how much closer I could get due to the crop.
Now I want to achieve this magnification with my FF. It doesn't have to be x 1.6.
What's the best way to do this?
- Extension tubes?
Although I only see threads for deciding between ext. tubes OR macro lens
- TC?
- Other methods?

Thanks for your input ;)

The 5D and 100mm f/2.8 makes for a great macro combination. The IQ of the 5D means you can crop to 100% and still have perfectly useable images.

If you want even more magnification, then extension tubes are the way to go (I use Kenko ones).

For more magnification on top, you can add a teleconverter to the extension tubes. Be aware though, that the more "magnification" you add, you decrease the depth of field until it's only millimetres thin.

A full set of kenko tubes with a 100macro on a 5D will give you approximately the same field of view as the bare 100macro on the 40D. A 1.4x teleconverter will be slightly wider a 2x will get you to 2:1. I think your best bet would be the extension tubes. They will maintain IQ(unlike a teleconverter) and will give you a variable mag. because you can use just one or the whole set.

Here is where it was explained to me: https://photography-on-the.net/forum/showthre​ad.php?t=764925

The Canon Life Size Converter is quite an unknown accessory but works very well. This is both a TC AND an extension tube with a high IQ. It will achieve 1.6x MM with the 100mm. And contrary to what Canon says, it will work with any EF lens.

The advantage of the TC in macro is that you keep a longer working distance with the subject.

If you just crop down the 5D image to the same angle of view you will have a 5 megapixel image that is otherwise identical to the 40D. Try upres. to make that 5MP image print at ~240 dpi for the print sizes you have in mind and see if that is adequate.

If not....buy a used 40D or even cheaper, a used XSi.
