HD Pentax-DA 11-18mm F2.8 ED DC AW and HD Pentax-FA 35mm F2, new lenses for SLR cameras with APS-C / FF sensor and K mount
Ricoh, owner of the Pentax brand, has announced the release of two new lenses for its K-Frame SLR cameras. The first is the extremely wide Pentax-DA HD ★ 11-18 mm F2.8 ED DC AW zoom lens, which is integrated in the Star series of the highest quality and is designed for cameras with APS-C sensor. The other is the Angular HD Pentax-FA 35mm F2, designed for cameras with full-format sensors. It is nothing more than an update to the classic look of the catalog with its latest optical technology.
HD Pentax-DA ★ 11-18mm F2.8 ED DC AW
As we said, the first objective presented is of variable focal length between 11 and 18 mm (which in the cameras to which it is destined becomes 17 – 27.5 mm ) with a constant luminosity ƒ2.8 in the entire range of zoom Integrated into the most exclusive family of the house, the Star , the new HD Pentax-DA ★ 11-18mm F2.8 ED DC AW promises ” exceptional optical performance […] adjusted to the needs of the high-performance digital cameras of the future ”
Thus, always according to the press release, the optics offers ” high resolution images and contrast, without loss of edge sharpness, and guarantees excellent performance in high-level digital photography, even working with large openings .” The truth is that with the arrival of this objective the Star family is completed, which now covers practically the entire focal range , from the ultra wide-angle to the telephoto, with ” compact models offering a maximum aperture of f2.8 ” designed for APS-C cameras from Pentax.
Constructed on the basis of 16 optical elements organized into 11 groups , just like its range brothers, this new set of lenses has multilayer HD coating that ” reduces the average reflectance in the visible light spectrum to less than 50% compared to Conventional multilayer coatings “, which helps to minimize parasitic lights and ghost images.
On the other hand, the HD Pentax-DA ★ 11-18mm F2.8 ED DC AW has a body resistant to the elements and a mechanism to block the focus at a certain point (even when the focus ring is rotated), which “It improves the operability of the objective in landscape photography and starry skies, disciplines that demand a high precision of focus during prolonged exposures “.
For these same disciplines the objective also has a striking feature : A compartment designed to house heating cables around the barrel of the lens in order to avoid condensation and a metal frame that transmits more effectively the heat of the device to the objective.
For the rest, the HD Pentax-DA ★ 11-18mm F2.8 ED DC AW has a minimum focusing distance of 30 cm , a nine-blade diaphragm , a filter diameter of 82 mm and dimensions of 90 x 100 mm and 739 grams(parasol included) of weight.
HD Pentax-FA 35mm F2
With regard to optics designed for full-format DSLR (although they can also be used in APS-C with the consequent trimming), it is a standard wide-angle lens ” perfect for everyday use ” thanks to a very large size compact , according to Ricoh. As we already anticipated, the new HD Pentax-FA 35mm F2 is really just an updated version of the SMC Pentax-FA 35mm F2 AL , ” a very popular and versatile wide-angle optic ” (always depending on the manufacturer).
The idea, as you can imagine, is to provide it with ” the latest lens coating technology to offer a better image quality “. Thus, in its structure of six elements in five groups , hybrid aspherical optical elements and the same multilayer HD coating as the previous objective have been incorporated to improve the contrast and avoid detects and flares . In addition, the front surface also receives a coating against stains called SP ( Super Protect ) to repel water and grease.
Of course, the changes also affect the exterior, which ” has been totally redesigned to adapt it to the latest models of Pentax cameras of the DA and D FA series “. Otherwise, its minimum focusing distance is 30 cm , its diaphragm has six blades , the diameter of the filter is 49 mm and it has an approximate weight of 193 grams and a length of 44.5 mm .
