On a recent early morning trip to Ontario’s Tiny Marsh Provincial Wildlife Area for some sunrise photography (more on that shortly), I also made my way over to the boardwalk trail for some frog photography. I was hoping for lots of Leopard Frogs but none were to be found, however, there were many Green Frogs. The wetland surrounding the boardwalk at Tiny Marsh has lots of duckweed growing in the water now and this makes for some lovely images of frogs, as they poke their heads above the water’s surface.
The Green Frog in this post was located rather close to the edge of the boardwalk and very cooperative too. The problem here was that the light was too dark to handhold my Nikon 105mm Micro lens, at the desired aperture of f-16, for a decent image and using my trusty Nikon SB400 Speedlight was ruining this scene as it was creating numerous unpleasant highlights throughout the duckweed. The solution to photographing this frog was to use my tripod mounted Nikon 80-400mm VR lens, but the minimum focusing distance of this lens is roughly 7 feet and this frog was only about 2 inches in length – how would I do that? Well this is where I have to breakdown and admit that I was forced to make a switch to Canon :) A Canon 500D Close-up lens to be exact. This close-up lens, with 77mm threads, is essentially a double element filter that simply screws onto the front of the lens as any filter would normally do, but it reduces the focusing distance of the lens drastically, allowing the 80-400mm VR lens to be used as a macro lens whenever I need it to, at a fraction of the weight and price of carrying an additional lens into the field. A polarizing filter was also attached to the front of the Canon close-up filter to reduce much of the undesirable glare from the duckweed.
Alternately, as I sit here writing this blog post I am charging the battery for my newly purchased Nikon D800. If I had this camera in my hands last week when I visited Tiny Marsh, I most likely would have cranked up the ISO and fired away with the handheld 105mm micro lens. Ain’t technology grand :)
