Lens Test: Pentax-D FA 100mm f/2.8 WR Macro
1 April 2013
Excerpt: With a sleek, retro style, Pentax’s latest version of its 100mm f/2.8 macro looks much different from earlier iterations. The $700 (street) lens, joining the WR (weather-resistant) line, now has a metal body instead of reinforced polycarbonate, and a metal manual-focusing ring, along with weathersealing. Perfect for nature and travel photographers who are hard on their glass.
Conclusion: Considering its construction, it's also lighter than expected, and the weather sealing doesn't appear to add anything to the price of the non-waterproof version. It's just a shame that its focusing system isn't quite as refined as those found in other macro lenses.
Excerpt: Pentax already has a 100mm macro option in its range - the Pentax smc D FA 100mm f/2.8 Macro - but this newer version has the advantage of weather resistance. This combines six separate seals to keep out moisture, together with a Super Protect coating on the front element to repel any droplets, dirt or grease, making it an ideal match for Pentax's weatherproof K-5 and K-7 bodies.
Excerpt: Comprising an internal arrangement of 9 glass elements in 8 groups, it feels reasonable in the hand despite being light at 345g. Capable of focusing within 30.3cm of any subject, the front element accepts 49mm filters and features a multi-layer coating, designed to minimise surface reflection, reduce ultraviolet rays and deliver high-contrast images.
Excerpt: Originally posted 2011-02-22 on Optyczne.pl Pentax doesn't have a good luck when it comes to lens tests on our website - for several reasons. One of the most important reasons was worse availability of Pentax’s optics on the Polish market. The situation has been changing lately, mainly because of the Fotozakupy.pl shop which has been enlarging its offer by products of this range.
Cons: slow, noisy and averagely accurate autofocus.
