Thanks to all your nice comments, I'll try to post as much as pictures I can and I also want to share their pictures as they grow. As of now I'm taking these photographs on a Sigma 18-50 mm f2.8 macro lens, I'm still in the process of acquiring Sigma's 105 mm f2.8 macro lens...and more T's to come. Again thank you very much for the kind words.{D
Looks like that sigma is treating you quite well. I wish I could justify buying a nice lens right now, keep up taking those nice shots .
I'm a huge fan of macro photography and I like to think that I'm pretty good at it... Your macros of all these slings are amazing. No lie...and you also won my vote for picture of the month for November of your blue fang sling on another forum. Definitely keep on posting!
