Originally posted by Douglas_of_Sweden Basically I agree with Adam. I presume this is natural light (?), and then it is hard to get more contrast unless you use a sharp and contrasty dedicated macro lens. So it could be worth trying using flash? Non the less, I like it. Nice colors and well composed (though a bit tighter cropping keeping the flowers on the diagonal could work better). And I'm impressed that you managed to get all of the butterfly within the DOF with just f6.7. What focal length was it shot at?
Yes natural light, very over cast, dark clouds looked like rain the whole day.
I was about 300mm using the Sigma 50-500mm lens...hand holding...
Overall I was quite pleased with the lens...always room for improvement but I appreciate what others have to say and makes me think about the next time.
