Legendary Biotar 75 F1.5 Lens Officially In Development By Oprema Jena

A while back we mentioned reports indicating that Myer Optik or Zeiss could be looking into relaunching the famed Biotar lens lineup, specifically the legendary 75mm F1.5. Now those reports have been officially addressed by a company called Oprema Jena, a sister company to Myer Optik, in an email both confirming the reports about the development of the lens and explaining those involved in the project.

Yasuhara Introduces AF-Coupled Macro Extension Tubes for MFT and NEX

Yasuhara Nanoha Macro Extension Tubes

Yasuhara, the Japanese company that brought us the Nanoha macro lens for Micro Four Thirds, has just introduced a set of AF-coupled macro extension tubes for Micro Four Thirds and Sony NEX. The tubes sport electrical contacts so that autofocus and aperture functionality are retained, and come in a set of one 10mm and one 16mm tube. On the US market, each set (NEX and MFT) will be available for US-$ 159.

Technically, we assume the Yasuhara tubes to be similar to the ones that Kenko introduced early last year. While both the Kenko and the Yasuhara tubes come in a set of 10mm and 16mm tubes, the Yasuhara tubes appear to be the more affordable solution. Whether or not they’re of the same quality as those from Kenko (which we reviewed here) will be seen once we receive review units.


Tokina Announces AT-X 12-28mm f4 Constant Aperture Wide-Angle Zoom Lens for APS-C Cameras

Tokina AT-X 12-28mm f4 for APS-C

Tokina has just announced a new wide-angle zoom lens for APS-C cameras, the AT-X 12-28mm f4. With a focal length equivalent to that of a 18-42mm lens on 35mm full-frame, the AT-X 12-28mm f4 offers a constant aperture rating of f4 at all zoom positions. Thanks to an optical design making use of aspherical elements and super-low dispersion glass, Tokina promises enough resolution to match even the highest megapixel-counting APS-C DSLRs currently on the market. A new AF mechanism furthermore promises faster and quieter autofocusing. Full specs after the break.

Video Review: Kenko DG Extension Tubes For Micro Four Thirds

A couple months ago, Kenko announced a new set of macro extension tubes for both Micro Four Thirds and Sony NEX. These extension tubes make it possible to use any MFT- or E-mount lens for macro photography, by spacing it further from the sensor and subsequently retracting the closest focusing point. What makes these particular extension tubes special is that they feature electronic contacts which allow for communication between lens and camera, thus retaining full autofocus capability and aperture control. In this video review, we are presenting the Kenko DG Extension Tube Set for Micro Four Thirds. The NEX version has been briefly discussed in this article. Continue reading…

Kenko Announces Electronically Coupled Extension Tubes For NEX and MFT

Kenko has just announced a new set of extension tubes for Micro Four Thirds and Sony NEX. While these are not the first extension tubes that Kenko has introduced, these are the first that come with electronic coupling. With these extension tubes, virtually any lens designed for Micro Four Thirds or Sony NEX can be converted into a macro lens. By moving the lens further away from the sensor, the extension tubes allow for much closer focusing and thus much higher magnification ratios. The tubes come in sets of 10 and 16 mm spacers that can be combined to 26 mm, enabling true macro capability.
