I visited Huntley Meadows Park on 30 November 2014 for my first foray into macro photography. I field tested a new Raynox DCR-250 close-up filter with my Panasonic Lumix DMC-FZ150 superzoom digital camera and Canon 580EX Speedlite external flash (fitted with a Sto-Fen OM-EW Omni-Bounce, an inexpensive plastic snap-on flash diffuser). The Raynox DCR-250, like other close-up filters and extension tubes, reduces the minimum focusing distance between the lens and subject.
The following photograph of a male Autumn Meadowhawk dragonfly (Sympetrum vicinum) was taken at maximum telephoto zoom (24x) without using the Raynox close-up filter. The camera was positioned near the mininum focusing distance from the subject, in this case approximately six feet (~6′). The photo was cropped from the original size of 4,000 x 3,000 pixels (12 MP) to a pixel size of 2,690 x 2,016 (5.4 MP), in order to enlarge the subject and improve the photo composition.

The same dragonfly perched on my pant leg a while later. The next photograph was taken at ~12x zoom using the Raynox close-up filter. I estimate the “working distance” between the camera and subject was approximately three-to-six inches (~3-6″). Now that’s what I call a cooperative model! The photo is uncropped from the original size of 4,000 x 3,000 pixels (12 MP) and edited lightly.

Dragonflies have the finest vision in the insect world. The compound eyes in the largest species have as many as 30,000 simple eyes (ommatidia). Source Credit: Paulson, Dennis (2011-12-19).

The next photo shows another male dragonfly perching on the boardwalk. The picture was taken at ~6x zoom using the Raynox close-up filter. The working distance was an estimated six-to-10 inches (~6-10″). The photo was cropped to a size of 3,407 x 2,555 pixels (8.7 MP) to refine the photo composition.

The last photo shows an unknown species of grasshopper. The picture was taken at ~12x zoom using the Raynox close-up filter. The working distance was an estimated three-to-six inches (~3-6″). The photo was cropped to a size of 3,593 x 2,693 pixels (9.7 MP) to refine the photo composition.
ISO 100 | 56mm (~300mm, 35mm equivalent) | f/7.1 | 1/160s
The Raynox DCR-250 close-up filter is a relatively inexpensive solution that enables my Panasonic superzoom digital camera to be used for macro photography. Set-up is quick and easy — the filter simply clips on the front of the camera lens using a universal adapter, just like a lens cap. Depth-of-field is very shallow! A cooperative subject, good light, and a lot of patience are essential for success.
