$25 Macro- Taking Meike Auto Extension Tubes for a Spin

I originally purchased purchased these inexpensive tubes thinking they'd be a good match for the Sigma 60mm F2.8 DN Art. Using both the 10mm and 16mm tubes together got me 5" of working distance and nearly 1:1 macro. 

The drawn box below is the size of M43 sensors. The 60mm Sigma almost gets 1:1 (life size) magnification here. Working distance was about 5 inches.

21.5mm x 17.3mm 

10mm + 16mm Tubes- Minimum focus distance is 5 inches.
16mm Tube Only- Minimum focus distance is 6.5 inches. 

10mm Tube Only- Minimum focus distance is 8 inches.

Sigma 60mm f2.8 DN without the extension tubes. 

Below are some sample images SOC... at the moment I am not a fan. It looks like lens flare and really poor contrast.

Really bad contrast in this shot.
