Posts Tagged ‘Tamron 18-400mm’

Every now and then one of my readers will ask me to post photos of Occoquan Bay National Wildlife Refuge, my favorite local wildlife photography spot. Usually I have either a telephoto or macro lens on my camera, neither of which is all that suitable for landscape-type shots. If I thought about it, I could switch to a wider lens and generally have one with me in my backpack, but it is kind of a hassle to do so.

This past week I have been finally shooting with my Tamron 18-400mm zoom lens, which I bought months and months ago, but had rarely used. This lens gives me good all-round capability in terms of focal length, but I wasn’t sure how it would handle the kinds of shots that I like to take. Could it handle macro-style shots of dragonflies? How would it handle birds, especially birds in flight?

I am still working on the answering those questions, but so far the results look promising. The dragonfly photos in my past two postings were taken with this lens, as were the landscape photos in this posting. One of the challenges of using this kind of all-in-one lens is that I have to retrain my eyes to look everywhere—when I have a long telephoto lens on my camera, I look mostly into the distance and when I use a macro lens, I look mostly at areas that are close to me.

As you can see in these photos, water is one of the features of this wildlife refuge. Sometimes I search for subjects near the ponds and streams and at other times I focus my attention on the wider waters of the bay. At this time of the year, the vegetation is green and lush. Fortunately the foliage on the trees provides some respite from the oppressive heat that is common here in the summers.

We are at a time of the summer, when it is unlikely that I will see any new dragonflies for the season. Several species will emerge towards the end of the summer, but for now I see the same familiar faces over and over again.

I really am content, though, with photographing the beauty of these wonderful aerial acrobats and never grow tired of photographing the same ones over and over. Each outing with my camera is an opportunity to capture images in a different way, in different environments, and in situations with different lighting.

Last  week I was delighted to capture these images of male Widow Skimmer dragonflies (Libellula luctuosa) during a visit to Occoquan Bay National Wildlife Refuge. I just love the brown and white patches on the wings of these dragonflies that make them really stand out from all other dragonflies in our area.

These shots also illustrate the fact that the shapes of the front wings of most dragonflies are different from the rear wings. I suspect that the different shapes play a role in enabling the amazing flight capabilities of dragonflies, although I confess that I do not understand very well the aerodynamics of dragonfly flight—their flight seems almost magical to me.

Dragonflies perch in many different ways and in many different places. Here are some simple shots of three dragonflies that I encountered last Thursday at Occoquan Bay National Wildlife Refuge.

The first one is a Needham’s Skimmer (Libellula needhami) and I love the way that its coloration contrasts so well with the sea of green vegetation in which it is perched. The dragonfly in the second photo, my personal favorite of the three images, is a Blue Dasher (Pachydiplax longipennis). When it’s hot outside, some dragonflies, like this one, like to assume a handstand-like pose, often called the “obelisk” position, to reduce their exposure to the direct sunlight. The final photo shows a Great Blue Skimmer (Libellula vibrans) perched on the tip of a leaf.

Each of these shots represents my efforts to isolate a dragonfly a bit from its surroundings and to highlight its beauty and its behavior. None of theme is spectacular or award-worthy, but they are pleasing little portraits of some of my summer companions.

It was hot and humid when I went trekking with my camera this past Wednesday and most of the wildlife seemed to be taking siestas in the shade at Occoquan Bay National Wildlife Refuge. I could hear the sounds of birds, but spotted only a few of them. Even the dragonfly activity seemed to be lower than normal.

Fortunately, a good number of butterflies were active. In fact they were so active, that I expended a lot of energy chasing after them. I noticed that several of them were showing some wear and tear, with visible damage to their wings.

The first and third photos show Black Swallowtail butterflies (Papilio polyxenes), while the butterfly in the middle shot is a Zebra Swallowtail butterfly (Eurytides marcellus). None of these images is spectacular, but I like the way that they work together as a set, with the green vegetation in the background of each of them serving as a unifying element.

Have a happy weekend and chase a few butterflies if you can find them—it will make you feel like a child again.
