This morning as the sun came up the dew was thick upon the grass and near me was the camera with the 200-500mm lens on it. Nikon says it is good for macro photography so why not? Being a 6 pound lens it is a bit unwieldy for a lot of close work (close being relative, roughly 5 feet away) but it did yield nice, crisp shots with beautiful bokeh even at f5.6.
UPDATE: I spotted a hummingbird from a long way off. Take a look at the uncropped and cropped photos. Not bad. Remember this is with a D810 and the 200-500, handheld.
Yesterday the Nikkor 200-500mm f5.6E arrived and it seems like suddenly all the critters in the backyard disappeared! There will be a lot of experimenting to get used to it and find the best settings for various situations. I started this morning with a few shots of the dog and then, through a window, I managed to get this squirrel with a nut in its mouth running across the yard. So, early trials but it is a very solid lens and a great value.
I have often been told by professional friends that giving yourself an assignment is the best way to keep yourself engaged and learning in your photography. I have done this in various ways, but especially in just taking pictures of what I see everyday. A recent post on Digital Photography School makes the same point. I even have an entire flickr set just for backyard photos. These few show some extremes in lens length.
