I agree with Peter
Wow, this is an excellent photo.

Thanks.

A Pentax K-5 and the Pentax 100 mm macro lens with a 1.4 Vivitar converter. The lens was set at magnification of 1/1.5. The combination of lens and converter produced a 1:1 image on the 24 x 16mm CMOS sensor.

The image was then cropped closely to the object as recommend by BugGuide. A Pentax Ring Flash set on through the lens auto provided the light. Lens opening set a f/32. Hand held. The flash provided the light to allow the f/32 opening. F32 opening resulted in large depth of field that made the manual focusing less critical. ISO was 400 so the flash duration was minimized. Took quite a few images some somewhat better than others.

Major credit goes the the extraordinary resolution of the sensor. If sensor reselution continues to improve soon one will eventually not need to change lenses but simply use a fixed lens and vary effective resolution. Of course we are not there yet.

Equipment was good but I would imaging equivalents from different manufactures would have done as well.

At first I thought the images were fuzzy. Then I realized it was the fly that was fuzzy -or rather hairy.

nice picture
I'm interested in how you get such a good photo of something so small. What do you use?

Glad you asked
