Macro Continued Using Extension Ring

I spent a bit of time yesterday, trying out my Zeiss 50mm lens with a 16 mm extension tube. It was difficult to handnold at the correct distance as the depth of field is very small even at F22 so I used a monopod to support the lens. The bee is less than a cm and most of the subjects much smaller so some cropping still needed. The second image is the larva of the Marmalade Hoverfly (image 3) - great for gardeners as eats aphids.

Yesterday, we did a different local walk through a very large Barley field over the hill to one of the local golf courses. It was windy and cloudy when we started but the skies later cleared giving much more contrasty conditions.

Photographing a Leaf Insect Egg with Coupled Lenses for Extreme Macro

Having used the setup with a single reversed lens (image of set up at end of this post), I decided to try the two-connected-lens technique for extreme macro.The set up included glueing two filter rings together with the screws to the outside to allow two lenses to be connected lens to lens. I used the Olympus 50mm with aperture set to 1.8 and a 10-24mm Fuji lens. The Fuji needed to be used at 24mm zoom length to give sufficient circle of view. It was mounted onto a focusing rail over a lightbox. The egg is only about 2mm and the focusing distance less than 1cm so an LCD light was needed to get light onto the subject. Also photographed an Eyed Moth wing - shows the individual scales in detail (first image). The second moth wing and the White butterfly wing were photographed with the single reversed Olympus 50mm lens.

Four-spotted chasers Emerging from Our Pond

I missed the first 3 or 4 emergences from the pond this year, though one later visited the pond most days. So I was pleased to find two yesterday morning and cover the stages showing just escaped from the larval case to just beginning to colour up on the wings.
