Is DPReview just Hopelessly Anti-Pentax?

This is pretty darn close to being spot on. The only thing I would add is that many over there lack a sense of humor.

Mirrorless bodies are safer for vampires to use during lens changes.

My 2 macro workhorses are the DA 35 LTD macro and the DFA 100 WR. When the WR came out, I replaced my Sigma 105 macro which in its own right was a very good macro lens. I don't consider the 35 too wide either. Plus it can be used more like a closeup lens as well as macro.

Super Protect (SP) CoatingSP Coating

SP coating is a PENTAX-original special coating that provides superior performance in repelling water and oils. It is used on the front surface of the first high-performance lens for effective protection of the lens surface. This coating not only prevents adhesion of dust, water drops, oils, and other substances, but it also makes it easy to wipe off objects that adhere to the lens.

HD CoatingHD CoatingAbout HD Coating

Typically, multicoatings are formed by using vacuum deposition to apply a thin layer to the lens surface. However, this fabrication process also presents problems because of the difficulty in increasing the density of the coating film and the variation in refraction rates and film thicknesses. PENTAX's solution to these problems was our HD Coating, which is fabricated using PENTAX's exclusive special fabrication process, where high-density film is applied with high precision at the nanometer level. This enables the reliable formation of the designed film thickness for a dramatic reduction of the reflection rate (up to 50% compared to conventional coatings) over the entire visible light range. It is also effective in reducing ghosting and flare. Moreover, the film coating has an extremely high hardness for providing superior durability.

Multicoating, Ghostless Coating,
and Internal Reflection Prevention


PENTAX interchangeable lenses use our unique multicoating for reducing the surface reflections to approximately 1/10 of single-layer film coatings. This coating increases the transmissivity of light over the entire visible light range and also nearly completely cuts out harmful UV light. This coating also reduces ghosting and flare under backlighting and other adverse conditions for providing images with a high sense of transparency.
Moreover, some lenses use PENTAX's exclusive ghostless coating for reducing reflections from specific types of light for minimizing the occurrence of ghosting. PENTAX performs the optimum control of each coating for each lens to match the lens configuration, glass characteristics, and other factors.
Also, flocking and paint are combined for preventing reflections inside the lens barrel. A light shielding mechanism is installed to prevent scattering of light from a lens within the lens group together with other measures for minimizing ghosting and flare.

Aero Bright CoatingAero Bright CoatingAero Bright CoatingII

Aero Bright Coating is PENTAX's newest lens coating developed from nanotechnology. It uses a silica aerogel coating layer with uniform porous structure applied over a regular multicoating. This traps low-refraction air between stable silica nanoparticles for enabling a coating with super-low refraction rate and high transparency. The coating has greatly reduced surface reflection. In addition, using a new super-low refractive index layer formation process, we have developed Aero Bright Coating II, which enhances low-reflectance properties.

Seriously? You realize my post was from 8 years ago? The article you just posted didn't exist until recently. In fact, Ricoh didn't have Pentax yet.

Both are good lenses. For what you want, I think the 43 will have "character" for portraits. Could be the Pixie Dust in the coatings.
