Aquilegia Vulgaris

Very nice, I'll assume this is the Pentax 100mm macro please let as know,

Jack.

Thank you Jackitec, Yes it was the Pentax 100mm macro. I usually, automatically use the Pentax 35 mm macro but could not get close enough without damaging other plants with the tripod legs. I do not understand the difference between F/stop and Aperture Value when displayed by the Exif data for other members shots in the Gallery. I thought F/stop was the ratio of focal length divided by the aperture diameter, for any given lens. Perhaps we obtain different values for a collection of lenses within a lens assembly, where can I find a definition, please?
