I'm off the Bempton Cliffs tomorrow with a birding friend. I haven't got a long lens, so I spent today trying out a x2 converter on a 300mm lens. I've used it before for wildlife stuff and been generally disappointed with the sharpness. I tried much harder today but still think something's lost in the quality, but it'll have to do. This comma would probably have been sharper without the converter.
