Good fun lens
I have made close-up photos with Nikon 60mm f/2.8 and Pentax 100 f/2.8. In comparison, the Nikon 60mm has better resolution. However, I much prefer the 100mm in real life. The Pentax 100mm and other 90mm and 105mm macro lenses allow me to be much further away from the insect so that it doesn't get frightened and move away. The Pentax 100mm is small and light for a macro lens. Given the long working distance and the small lens diameter, I can actually use the built-in flash for a 1:1 macro photo, which is impossible with a 60mm or 50mm macro lens. The 100mm also makes a very decent portrait lens. However, this Pentax lens has two weaknesses. First it is not the sharpest lens I own; the Pentax 50mm f/1.4 is. Second, auto-focus is slow and unreliable, except near infinity. Manual focus is required for close-ups; but the focusing ring is slightly loose and could be more precise.

great lens for macro but for portraits as well
it takes some time to get used to shallow DOF when taking photos on high magnification with wide aperture. auto focus speed is acceptable.

you can use it for portraits and other photos, not only for macro.

Love it!!
I really love this lens, The closeups are great. Iv been into photography for years and always wanted a macro lens, and I don't regret getting this one. The sharpness blows me away. I do recommend this lens.
