Not as much as a real macro lens on an SLR. I've seen folks quote ratios and numbers and such. It'a about 1:7. The minimum focus distance is 18" (give or take). 18" on my Canon 50mm macro lens says 1:7 on it's magnification scale.

It's a lot better than the usual 3' minimum of rangefinder cameras. Very useful. The DR Summicron is NOT a macro lens.

Two examples

The first is the Nikkor 50mm 1.4 at or very close to minimum rangefinder focus distance, EDIT: about 3 feet.

The second photo is the 50mm DR Summicron at 18".

Same plants and same dragonfly.

I'm thinking you meant 3', not 3" 😉

Yup! Good catch! I corrected myself.

If I was wrong and you were right, I was going to buy one immediately!

The Nikkor 50 does focus to 18". However, without benefit of rangefinder coupling like the DR Summicron. 3"? That's bellows territory! 😀
