I combined my new macro teleconverter with a full set of extension tubes, to see what kind of magnification I could get. The weather being what it is, I was a bit strapped for subjects, but luckily for me (and unluckily for her) my wife's tomato plant has recently had a small aphid infestation
I also managed to locate a tiny spider, about the same size as the aphids. All shots are uncropped.
These shots were taken using a Pentax AF400ftz off camera. I don't have a flash bracket, so I was holding the flash in one hand and the camera in the other. It's funny how no matter how much gear you have, there's always something that would have come in handy.
