Amazing IS (Image Stabilization) of the Canon EF 100mm f/2.8 L IS USM Macro Lens.
2nd test, 1:2 or 0.5x macro range. All handheld, 1/50s, F5, ISO400
Left side: IS On.
Right side: IS Off
I took 5 shots first with the IS on, then another 5 with the IS Off. I then opened them all up in ACR (Adobe Camera Raw) and adjusted only the WB and Exposure/Brightness. The rest all default setting of ACR.
I then did a 100% crop before pasting them all into one image for easier comparison.
You have to view the Original to see the differences.
