The week before last I bought a 75-300mm lens for my camera on ebay. So last weekend I took it to Battersea Park to try it out. I took a few too many photos. One or two of the photos are cropped, but they should be obvious. The rest are what I got with up to 300mm zoom.
The lens is wonderful, though with a polariser (which came free on it) you need plenty of sunlight to get a high enough shutter speed to hold it by hand. I would love a stabilising lens, but they are expensive
