Yesterday was my birthday but the planned day out didn't happen because it rained nearly all day. Ah well. At about 6pm Rob and I went to Sevenoaks Wildlife Reserve, me armed with Rob's D700 just for the hell of it. Coupling a full-frame camera with my 300mm f4 + 1.4 teleconverter gives about the same magnification as the 300mm on its own with my D300's crop sensor. In other words, not really enough for most bird photography... but I was interested in seeing what the D700 made of some really low-light situations.
