A series of Osprey Platforms with nest images from the Edwin B. Forsythe NWR in Oceanville, NJ. I was using a Tamron 150-600mm lens with a 2X teleconverter to get closer to the Osprey Platforms. Then cropped in a little for a tighter composition. You can see the nests are not the neatest or cleanest when you are looking that close, but are still interesting. Also it is interesting when an Osprey sees you photographing them they really stare you down! The Canon R, even with a 2X teleconverter on a Tamron 150-600mm auto focuses quite quickly and right on focus. The Canon R will autofocus even with stacked 2x & 1.4X (or 1.7x) teleconverters. Did not try stacking 2X Teleconverters. I have also found that when stacking teleconverters I usually stop down a little more to help with sharpness.

For some reason Blue Dasher Dragonflies seem to look like they are smiling when you see them head on, giving an impression of a Happy Dragonfly. This Blue Dasher was out in a pond at a public county park, probably 6 to 8 feet from the shoreline. The featured image is a 4 shot Image Stack, manually focused and assembled in Photoshop. I used a combination of a 400mm lens, an extension tube, then a 1.4x teleconverter to actually enlarge the image on the sensor with the extension tube added. Sometimes I add another extension tube between the teleconverter and the camera body which enlargens the image on the sensor even more. But narrows your focus range even more and you tend to need a fill flash because of loss of light reaching the sensor to get a usable exposure for a subject that is somewhat moving its head or wings or its perch is moving in a breeze. Plus the added extension tubes also takes away light reaching the sensor. Sort of like the “Old” days when you were using a 4×5 or 8×10 view camera when you had the bellows racked out and had to adjust your exposure because of light loss from the distance of the lens and the film plane. By moving teleconverter and extension tubes you can get a variety of focus windows and enlargement of your final image on the sensor.

Some of the time, when photographing Dragonflies, I need to get closer, but water or something is in the way. Or I just want more working distance and do not want to use a macro lens with skidish subjects. After photographing them for over 10 or 12 years I have come up with different solutions. And I want a really soft looking backgrounds! Or I am at a National Wildlife Refuge where you can’t go off the Drive, so you need more reach for the different dragons you see there. So I have come up with different combinations to solve that problem. The more you experiment, the more combinations you come up with. I sometimes use a telephoto lens, usually 400mm f/4, an extension tube, a 1.4x teleconverter, and then a longer extension tube. Sometimes I add another 1.4x teleconverter at the camera. Than add a flash with a Better Beamer Flash extender because with the extension tubes I loose a lot of light, so I need more power to light my subject Dragonfly. This gives me a working distance, depending on which extension tubes and combinations of teleconverters I use, from 2 to 8 ft or even more, but filling the frame with my subject small Dragonfly. The Blue Dashers are about 1.5″ long. Some ot the others are a little larger and the Damselflies are smaller. The extension tube spacing actually enlarges the Dragonfly image on the sensor. But you do loose a lot of light. It seems awkward, but once you get used to the combination you use, it gets easier to use in the field. Many times I actually shoot a stack series of focus point images along a dragonfly to get a sharp final image from head to tail, wingtip to wingtip or specific areas I want in Photoshop. I probably posted too many images, but it shows the effects and details I was going for. They are such fascinating photo subjects! Sorry for such a long Post!

When it is a slow day finding subjects, sometimes I try different ways to photograph my subjects. This day was very quiet and the Ducks were really far out on the lake. Not to much was flying by and even the Canada Geese were gone. Quite often the wildlife is quite far out in the water or on the far shore. This Ring-billed Gull landed on a duck box giving me a subject. It stayed for a while so I thought I would try stacking teleconverters. I used 1.4x and a 2x teleconverter on my 300mm f/4 lens. The 1.4x adds 1 stop. The 2x adds 2 more stops. So that combination brought me up to f/11 at 840mm and with a 1.3x crop body, 35mm equivalent is 1092mm. Being a photographer for so long, using teleconverters in the early days, I always used to add 1 or 2 stops when shooting with teleconverters. Now with teleconverters being much better I usually only add 1 stop, so I was shooting at f/16 with this combo. But using stacked teleconverters I probably should have added 2 stops to go to f/16. Even so it came out quite sharp. Good for static subjects.

We had heard that there was a Snowy Owl at the Brigantine Division of the Edwin B. Forsythe National Wildlife Refuge in Oceanville NJ, but we thought it had moved on or that we never could find it, if it was still even there. We mainly went to see the large flocks of Snow Geese. To our surprise we found 2 Snowy owls there. 1 around the bend from the other one, near the end of the Wildlife Drive before the wooded area. They were quite far out, but we were still surprised they were still there and we actually saw them throughout the rest of our time there. It was hard to spot them because it was warm and a lot of the snow had disappeared, leaving small clumps of snow out in the fields, so you were basically looking for a small “more vertical clump of white” out in the fields. They seemed to keep getting farther out in the fields as the day progressed. They are not great shots, but what I could get with what we had. I wish I had a tripod with me, which would have helped, but we were traveling light that day. I tried a few with stacked Teleconverters also. So with a 1.4X Canon Teleconverter, with a 2X Canon Teleconverter, giving me with the 1.3 crop of the Canon MkIV about a 1456mm. Not really a 1456mm, but equivalent to that field of view as a 35mm format. These were also handheld, but with that combination I had a max f/stop of f/11, so I stopped down one more stop to f/16 and raised my ISO to 1250. I was surprised the MkIV still auto focused with all that added on. After a series I then went back to just the 2X Teleconverter. With the 400mm DO, stacking that much with the Diffractive Optics took it’s toll a little. The 400mm DO works great with a 1.4X Teleconverter at all distances. With a 2X it works well unless your subject is pretty far out, then the DO optics get softer and a little gritty, so the Stacking teleconverters was pushing it. Anyway we still had fun seeing them. Thanks for looking.
