Thank you for the link Crystal, those photos were exceptional specially the last one.
Yes, I was very busy for a couple of weeks and then the cable connection problem, thank you for the inquiry.
Crystal, I personally like this lens very much. It has a very long range and it's very practical but heavy and extended, it looks like a bazooka! I know some say that it is not sharp enough wide open but the images below were all taken without a tripod and a big majority of them wide open. My personal problem with a shorter lens is that I always feel it's a tease. Even at 500mm most of the time you wish your had a longer lens. Of course it will never be as good as a Nikon prime but with good technique, it will be close enough, specially if you consider adding a 1.4, 1.7 TC to Nikon 300mm F4. With that set up you will be close to the speed of this lens at 6.3 at 500mm. And I'm not sure if with that set up the image quality would match what I get with the Bigma. Those shots at the soccer field are diluted crops of the original as they were shot from across the field, not bad, you can even see the eye lashe

These photos have not been properly sharpened and definitely not sharpened for the web.
Having said all that, at first, I mainly bought the bigma to shoot into the sun. The picture with the biggest sun in it, with the sun flares showing was the first JPG shot I made with this lens combined with the 2xTC. I didn't have the proper eye protection and I was trying to zoom hand held. That is what I was imagining taking on your porch.
Oh, by the way, a good number of those dragonflies I posted sometime ago were taken with this lens.
Best wishes.
