Very nice shots!
Definitely need your tripod with focusing rail for macro shots though. Even though I have VR on my Nikkor 105mm Macro, shots do not show their full potential when DSLR is handheld.
The One-Star review on that link is funny....LOL
"Warning! Heavy, stubborn chemical odor present on brush identical to this BC brush. The brush I bought at BB&B was identical but lacked the "Betty Crocker" logo."
