Flying insects, in this case bees. Go out to your garden, local park, farm or where ever and see how you do at taking shots of insects in flight. Flies and bees are pretty hard targets and make a good challenge.
Heres one I shot the other day with the HS20. Its one of three keepers and is the best of those three. Handheld and shot in shutter priority @ 1/800 sec.
If you like, email me your images and I will start a display gallery.
