On Sunday, I went to a Flying Circus show. Great fun was had watching WW1-era biplanes swoop and loop and buzz around.
I was using my longest, sharp lens, a Tamron (eh, what an I say, I'm broke) 28-200mm at maximm length. I was initially concerned I'd not have enough reach and have to do a lot of cropping, but I am happy to say I didn't have to do that.
During the event, a storm swept in and although it skirted by, it did present some excellent background, as you can see here.
