DPNow comment: We had been told that we'd have to wait for an official announcement on Pentax's new line-up of supersonic AF motor-equipped lenses lenses next week, during Photokina. But a sharp-eyed DPNow forum visitor brought the following news from the Pentax Japan website to our attention this morning. The lenses listed below, which work via two new contacts inside the lens mount of the Pentax K10D and later Pentax and compatible DSLRs, do not resemble the specifications of the proposed five new KA-mount lenses announced by Samsung, along with the new GX-10 DSLR, earlier today. There had been some uncertainty as to whether the lenses would be compatible with earlier KA-mount Pentax and Samsung DSLRs that do not feature the extra contacts, but the press release text implies that the old system of camera body-driven AF is accommodated in the new lebses. Whatever, things are certainly looking up for Pentax and Samsung KA-mount DSLR users. The same release also provides more information about the long-awaited pentax medium format DSLR.
Release Issued by Pentax:
