New Soft Box also does well with stacked lens: No large bugs out so had to go with a little more magnification these were shot with a 55mm F/1.8 reversed on my 105mm macro.

Not too shabby!

55-mm reverse-mounted on a 105-mm = 105/55 = 1.9x life-size at MFD.

Here is a comparison for the people that want to know how much difference that is.

No cropping 1:1 Macro

No cropping 55mm reversed on 105mm

Actually that would be at the max focusing distance at minimum focusing distance it would be 2.9x. With a macro lens you add the mag of the macro lens to the equation.
Nice shots!

Thanks. I do not do a whole lot of lens stacking since hand held is my personal preference. It is not real easy to be steady. They are not perfect, but I was pleased. Some are better than others.

I am going to try this lens combo, and shoot a metric ruler at MaxFD and MinFD, so we can see a side-by-side comparison.

I will post my results in the appropriate FAQ.

Could not find my metric ruler so used a standard tape right at 1in at 1:1 with reversed 55 right at 6/16ths my calculation is 2.666x

Your first photo is 1:1 with only 55-mm lens: 15.5-inch capture on a 15.5-inch wide sensor.
I measure your second photo closed to 5.4/16-inch, captured on a 15.5-inch wide sensor.

15.5/5.4 = 2.87x life-size.

Is this Minimum Focusing Distance, or Maximum Focusing Distance with 105-mm lens?

105mm is fully extended, and the reversed 55 is set to infinity

Looks like your soft box is working Well.

Please replicate same photo, with 105-mm lens set to 'infinity'.

Here you go looks like exactly 1/2 in or 8/16ths

Both set to infinity

Interesting. Looks like a dark vignette around three corners but a light colored one on the lower right. Any idea why?

Here you go (Both lenses set to infinity). looks like exactly 1/2 in or 8/16ths

15.5/8 = 1.9x life-size

Your photographic documentation proves BlurryEyed's assertion of adding 1x when using a macro lens at Minimum Focusing Distance (MFD)
