I now have my final pictures for the course! These are in the process of being processed into enormous 8" × 10" prints by some photographic laboratory in Northampton. All I need to do then is to stick these on foam board and write a description on how I managed to take them. All before Thursday 27th March!
In the meantime, I've been playing with a couple of extension tubes I recently bought via Amazon. These are lenseless tubes that screw onto the camera and shorten the focal length of any attached lens. The two tubes differ in width so you can vary by how much you shorten the focal length. With both attached plus my 14 - 42mm lens I can actually focus onto the inside of my daylight filter! These are not Panasonic lens tubes but they do have electronic connectors which comminicate successfully with the camera body allowing it to manage all the clever stuff like auto focus, metering etc. For micro four thirds readers here's the
link. This is a far cheaper method of getting some macro close ups compared with buying a bespoke macro lens. These tubes also provide a greater range of focus than compared with the add on lenses. I'll do a comparison of extension tubes versus add on lenses so you can judge for yourselves!
Here are pictures using extension tubes. The wider angle shots use the narrower tube (10mm) , closer shots use the 16mm tube and the extreme close ups use both (26mm).

A slug slimed primrose .. this seems to have been flowering all winter! |
|
The tubes do limit the depth of field considerably! F9 at 1/250. ISO 160. An image at f11 would probably be in full focus. |
|
Same primrose, focus on far petals. F8 at 1/320. ISO 160. |

Suggestive stamen |
Here is the add on macro lens for comparison.
|
This has an odd colour cast at the edges which can be a problem with add on lenses. I took this at f11 for greater depth of field. |
With an extension tube plus a narrow aperture (f22) ...

A rather slug eaten flower well passed its best! |
