Rokinon 100mm f/2.8 Macro Overview

Home in on close-up subjects with the Pentax K mount 100mm f/2.8 Macro Lens from Rokinon, which affords life-size 1:1 magnification along with a minimum focusing distance of 1'. This manual focus portrait-length lens also incorporates one high refractive index element and one extra-low dispersion element into its design to reduce chromatic aberrations and distortions throughout the focusing range. An Ultra Multi-Coating has also been applied to minimize flare and ghosting for increase contrast and color neutrality. A long focal length lens with close focusing abilities and a high magnification ratio, this macro lens is ideal for making close-up, detailed images of nearby subjects.

This 100mm f/2.8 lens features a Pentax K mount, and is compatible with full-frame sensors or APS-C sensors, where it will provide a 150mm equivalent focal length.
A bright f/2.8 maximum aperture is useful for working in a variety of lighting conditions and the minimum f/32 aperture helps to attain a long depth of field when working with close-up subjects.
One high refractive index element and one extra-low dispersion element help to control chromatic aberrations and minimize distortions throughout the focusing and aperture ranges.
An Ultra Multi-Coating has been applied to lens elements to reduce lens flare and ghosting for increased clarity, contrast, and color fidelity.
Featuring a macro design, this lens affords a 1:1 maximum magnification ratio along with a minimum focusing distance of 1'.
Benefitting working with especially close subjects, this manual focus lens features an internal focus design to maintain the overall lens length during use. Additionally, the front filter mount does not rotate when focusing to better enable the use of polarizers, graduated ND, and other filter types that require precise positioning.
A rounded nine-blade diaphragm contributes to a pleasing out-of-focus quality when using selective focus or shallow depth of field techniques.
This lens features a mechanical aperture coupling that permits the use of aperture priority and automated exposure modes, as well as the ability to control the aperture setting with Pentax DSLRs.

Hello, i'm french (sorry for my bad english), can you confirm that this lens is compatible with fuji XT1 without adaptator ring? Is the autofocus working on it? and last question, do you send lenses to France? thank you!
Asked by: Anonymous
This is a manual focus lens, however it will be fully compatible with the XT-1. You may calculate your actual shipping options/order totals by adding the items you want to a shopping cart. It will then list the shipping options, descriptions, ETA's and fees to your location.

Does it has an international warranty? I would like to import it to Malaysia.
Asked by: Rupam K.
The warranty included with this lens would be valid for the USA only for 1 year against defects. We do offer protection plans from Squaretrade in 2 or 3 year increments which cover the lens against accidental damage. Those plans can be compared by adding the lens to your online cart.

For mirrorless cameras, the lens comes with an adapter. Is the adapter removable? If yes, what the native mount of the lens for your particular mirrorless camera?
Asked by: Erik
The lens does not come with an adapter. The mount installed is specific to the MFT system. You could purchase the version for a Canon EF/Nikon F-mounts and then use an adapter like this: https://bhpho.to/3a9cMbo
