Hi guys. Thank you so much in advance for all of your help. Does anybody have any experience using / testing and / or comparing these two lenses : Sigma 150 mm f/2.8 macro vs. Nikkor 105 mm VR f/2.8 ? The sigma offers more distance to take photos of insects that could fly away if you get closer with a 100 mm lens. The other, the Nikon, has an excellente review + the VR advantage. Is the Sigma great in color reproduction when comparing with the Nikon ? Which would be your choice if you had the money ? Both are around the same price + / - $100.00 difference, which is not that much. Also, I am considering the Tokina 100 mm f/2.8. Money is not the problem, but the IQ and for macro photography purposes, which one is the best overall. Thank you for all your help.
