During the “off-season,” I use the downtime exploring new sites for wildlife photography and for experimenting with new photography gear and techniques. For example, I spent a few days in the “BoG Photo Studio” recently experimenting with extension tubes.
Macro extension tubes are inserted between the lens and the camera body and increase the distance between the lens elements and the sensor enabling users to focus on subjects much closer to the camera. Source Credit: Fujifilm Macro Extension Tubes MCEX-11 and MCEX-16.
The subject in this set of test shots is a toy frog. His name is “Señor Frog,” as in, “I seen your frog, Señor.” Just look at him. He’s SO CUTE, don’t you want to kiss him? I found Señor Frog in a geocache located in Fairfax County, Virginia USA; the item I traded for Señor Frog is cool but he is cooler!
Canon EOS 5D Mark II
The first photo was shot on 19 February 2016 using a Canon EOS 5D Mark II plus Canon EF 70-200mm f/2.8L zoom lens, the 20mm Kenko macro automatic extension tube (from a set of three), 580EX II Speedlite & Vello diffuser, and Vanguard Alta Pro 263AB tripod and Manfrotto 054 Magnesium Ball Head with Q2 Quick Release.
The original image is a RAW file (CR2), taken using manual exposure and manual focus; the flash was on and fired. The minimum focusing distance for the 70-200mm lens is 1.2 m (3.9 ft.). Adding the 20mm extension tube reduced the minimum focusing distance: at a focal length of 135mm, the working distance was ~1.5 feet; at 200mm the working distance was estimated to be 2-3 feet.
The next photo was taken on 18 February 2016 using a Fujifilm X-T1 digital camera plus Fujinon XF18-55mm (27-82.5mm, 35mm equivalent) “kit” lens, Nissin i40 external flash (TTL), and Vanguard Alta Pro 263AB tripod and Manfrotto 054 Magnesium Ball Head with Q2 Quick Release.
The original image is a RAW file (RAF), shot using manual exposure and automatic focus; the flash was on and fired. The working distance was ~30cm, the same as the minimum focusing distance for this lens. That’s fairly close to the subject considering no extension tubes were used! The 10mm “Fotasy” brand extension tube (set of two) works well with this lens, reducing the minimum focusing distance to ~7 inches (~18 cm). At that distance, it was impossible to see the entire subject.
The last photo was shot on 15 February 2016 using a Fujifilm X-T1 plus Fujinon XF55-200mm zoom lens, both “Fotasy” brand extension tubes (set of two, stacked together), Fujifilm Shoe Mount Flash EF-42 (TTL), and Vanguard Alta Pro 263AB tripod and Manfrotto 054 Magnesium Ball Head with Q2 Quick Release.
The original image is a RAW file (RAF), taken using manual exposure and automatic focus; the flash was on and fired. The minimum focusing distance of 1.1 m (3 ft. 7 in.) is estimated to be half as far using both extension tubes (10 + 16 = 26mm).
So what are the take-aways from my experimentation? The time to figure out how your gear works is not when the photo opportunity of a lifetime presents itself! My skill set now includes several photographic techniques for getting closer to the subject, thereby enabling smaller subjects such as frogs and odonates to fill the frame, that is, assuming these subjects are less skittish than usual.
