Any comment on Sigma 70-300/4-5.6 APO Macro Super?
I am using this lens. Mostly for close-ups, like flowers, insects and so on. Seldom use it with larger aperture, but at smaller aperture from F8 to F16, the colours, the contrast and the sharpness really pops. Even in low contrast situations like in overcast sky and under thick foliage, the orchid looks fabulous. I have even tried adding the 25mm Uniplus tube to get even larger magnification - works wonderfully, especially at 150 to 300mm, giving you a comfortable distance from the insect.
