New Samyang 100mm F2.8 Macro for Pentax
By PF Staff in Third-Party Announcements on Apr 4, 2015
The third-party lens lineup for Pentax has recently been strengthened by Samyang Optics' latest announcement: a manual-focus 100mm F2.8 Macro lens that supports life-size (1:1) magnification. Like other modern lenses from Samyang, this one uses the Pentax KA mount, which means it has an aperture ring with the "A" setting. Thus, on modern DSLRs, it will behave exactly as a Pentax A-series lens would and it will support all available shooting modes.
Samyang will also produce the 100mm Macro in 9 other mounts compatible with Canon, Nikon, Sony, Fuji, Samsung, and Four-thirds camera systems.
This lens covers the 35mm full-frame image circle and employs a modern optical design with one high-refractive index (HR) and one extra-low dispersion (ED) element. Its aperture diaphragm features 9 rounded aperture blades for a smooth, circular bokeh.

Since it has an aperture ring, the Samyang 100mm Macro could prove to be a viable (and more affordable) alternative to the Pentax D-FA 100mm Macro for photographers who plan to use extension tubes or other macro accessories.
In the US, this lens will be sold under the Rokinon brand name at a launch price of $549 USD. It is expected to start shipping in the third week of April.
In Europe, it will retail for €549, though we have not yet received any pre-order links from major Pentax retailers.
A cine variant of this lens (Samyang 100mm T3.1 Macro) designed for videographers will be produced in a variety of mounts, excluding the Pentax mount.
Samyang has recently made quite a name for itself within the Pentax comunity, as its recent lenses deliver premium optics, excellent build quality, and a selection that fills many gaps in the genuine Pentax lens lineup. Such lenses include fast primes like the Samyang 35mm F1.4, 24mm F1.4 and 16mm F2.0. Samyang also offers a full-blown 24mm tilt-shift lens for the K-mount. The availability of these lenses is especially welcome given the dwindling lens support from Sigma, a long-time user favorite brand.
We are currently working on in-depth reviews of the Samyanf 16mm F2.0 and 24mm F1.4 lenses and expect to publish them in the coming months. See also our existing Samyang lens reviews:
