Went to the Cockerell Butterfly Center yesterday (sat). I figured it might actually be cooler in there than outside despite the high humidity, but apparently they don't turn the A/C on until around noon so it was pretty hot. Still, it was an enjoyable outing and I came away with some shots I was happy with. I was using the Sigma 150 2.8 Macro and SB-800 flash with Lumiquest ProMax mounted on the RRS flash bracket. The bracket was quite useful, not only allowing the flash to be rotated around the camera but also tilted for nearer/farther coverage depending on the subject distance. Here are a few of my favorites (click on image for PBase page with full shooting info): NIKON D70    ---    150mm    f/5.6    1/320s    ISO 400 NIKON D70    ---    150mm    f/4.0    1/125s    ISO 400 NIKON D70    ---    150mm    f/7.1    1/125s    ISO 400 NIKON D70    ---    150mm    f/5.6    1/60s    ISO 320 There are some more in the gallery here: http://www.pbase.com/jkohn/butterflies and as always comments/critiques/feedback welcome.
