I was doing some plant photography with the tripod mounted Sigma 180mm macro I bought second hand in October 2012 when I noticed a very agitated carder bee, Bombus pascuorum, close by. I just had time to quickly move the tripod, focus and grab three shots before the very irritated bee flew off. Here they are. Click to embiggen:
Technically they are awful. Only the second in the sequence has any degree of sharpness. So why post them?
Because they illustrate just how much effort the bee was making to shake off a parasite. It can just be seen on the hind legs in the second and third shot. There may well have been more. Here's a 100% crop:
That was one irritated bee.
And here's one I took with the Tamron / flash setup last summer. Technically way better - but it doesn't tell the same story.
