I don't have one for that 150-500mm lens, that thing uses big filters and I think there generally expensive. Ill probably get one for it some day but right now I got the wallet on lock down till I get some bills paid off.
I don't think I have ever saw that many turtles before. there were actually 17 of them sitting on a few different logs
Nice shots. Do you happen to know what kind these are? I see there appears to be two different kinds, one I know is a Yellow-belly Slider, the other with the longer tail with reddish coloration on the neck and tail is unfamiliar to me.
