The weather this year has been brutal -it was 27C this morning at 5AM (80F for the metric challenged). So there's almost no such thing as finding a lethargic subject, and last year I became bored with shooting still life. So I decided to step outside my comfort zone, shoot with a mix of natural light (for the background) and flash (for the subject), and use the EF-S 60mm + extension tubes to get a break from the weight of the MP-E 65mm. The EF-S is easier to control when shooting free hand, and since I'm using natural light for the background I don't plan on going above 2x anyway (the lens + 37mm of extension). For this set I switched to a sugar syrup that I made with one part white sugar, one part artificial nectar mix, and one part water. The bees seem to like it better than the straight sugar syrup I was using before.
Tech Specs: Canon 70D (F11, 1/30, ISO 200) + a Canon EF-S 60mm macro lens with 37mm of extension + a diffused MT-24EX (+1/3 FEC) with head "A" set as the key and head "B" as the fill. This is a single, uncropped, frame taken hand held. I shaded the subject, so you can pretty much ignore the shutter speed since the light hitting the bee is primarily from the flash.
In this next shot I was getting a lot of natural light reflecting up from a sidewalk, and even though I shaded the subject I was still pretty close to the natural light exposure for it. But I had the flash set to second curtain sync so that it would be the last significant light source recorded by the camera before the shutter closed. I actually like the motion that I recorded in this one -makes it seem more "dynamic" to me. [IMAGE'S LINK: https://flic.kr/p/xw8wuK]Bumblebee in Lavender III by John Kimbler, on Flickr
