Pentax D FA 100mm f/2.8 Macro Reviews

Photozone reviews the Pentax D FA 100mm f/2.8 Macro and writes;
“The Pentax SMC-D FA 100mm f/2.8 macro is a very good lens which is capable to provide very high sharpness till f/16. However, the resolution could be a little better at f/2.8 whereas the contrast level is already excellent here. The bokeh (out-of-focus blur) is very smooth and buttery – an important characteristic for a macro lens. CAs and vignetting are very well controlled and not really field-relevant.”

User Opinions

Pentax D FA 100mm f/2.8 Macro User Reviews

Good fun lens | Rating: ★★★★☆
“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.” – by H. Liao

Pentax da f2/8 100mm macro lens | Rating: ★★★★★
“I love this lens.It has opened up so many new possibilities. I use it all the time. I love not having to zoom and focus when I’m shooting it gives me more time to just get good shots. “ – by A. Gift For You

Smaller than I expected. Fantastic results. | Rating: ★★★★★
“I bought this lens for flowers and insects. It works amazingly. At times the focus does “hunt” a bit, but I think that’s my camera more than the lens. I was expecting tight, crisp, high detail close ups and that’s exactly what I’ve been getting.. The effect is subtle but very pleasing and your portraits will be much improved I promise.” – by Michael A. Beacom

A difficult lens to review | Rating: ★★★★★
“This lens is TACK SHARP. You won’t find a sharper lens. This thing could resolve out to 200mp is my guess, but we won’t know about that given the current state of sensors. With well lit situations this lens is an AWESOME macro AND portrait lens. “ – by ssgman
