- Many of these were shot wide-open (I've posted a link to a much better image gallery w/ details of each shot)

Picasa Web Albums - MH - Pentax D FA 1... -You can view as a slide show (I've put some of the exif details right in the captions) or download the full JPG.
All of these are using the K-7 with the D FA 100mm macro.
I'm still trying to find out whether my macro is a good or bad copy. I am already sending in my DA* 16-50mm to Pentax for a bad front focus issue and am wondering whether to include this one with it.
