i just got my sigma 530 dg super flash and i put it to use doing some macros. here are some of my better shots! c&c is very welcomed, because i am very new to photography and would love to improve. i took the extreme closeups at 4 times life size by reversing a nikon 50mm f1.8 on my canon 70-200f4l. The old nikon lens has a manual aperture ring so i could easily change the aperature. the other pictures i stacked 68mm of extension tubes on a canon nifty fifty. 1. 2. 3. 4. 5. 6. 7. 8. 9. 10.
