Pentax DA★ 11-18mm and D FA★ 50mm Specifications

Reference exhibits at CP+ 2018

By PF Staff in Pentax Announcements on Feb 27, 2018

In preparation for the upcoming CP+ 2018 trade show, which kicks off on March 1st in Tokyo, Ricoh Imaging has revealed further details about the two K-mount lenses due for release later this year, including partial specifications.

We'll see the HD Pentax-D FA50mm F1.4 SDM AW premium normal lens for the full frame system this spring.  It will feature the latest KAF4 lens mount*, which incorporates electromagnetic aperture control.  In addition, this will be the first Pentax lens to use a newly-designed ring-type autofocus motor.  We expect this lens to deliver "corner to corner" sharpness, as has been the trend with recent modern primes.  It is possible that Ricoh will officially announce this lens in the coming days (as implied by the "one reference product" in the press release text).

The HD Pentax-DA11-18mm F2.8 ED DC AW is expected in the summer.  This will be a wide-angle premium zoom for crop cameras.  We've learned that it will use the KAF3 lens mount, which means it will remain compatible with older cameras like the Pentax K-5.  The lens will also feature a focus clamp to allow for very precise manual focus adjustments.

Other news includes the announcement of new lens roadmaps, which newly lists a D FA 70-200mm F4, and of course the announcement of the Pentax K-1 II.

*Cameras older than the Pentax K-3 will always shoot wide-open with this lens.
