Yesterday we wrote about the release of the first full-frame SLR Pentax. Now the manufacturer enriches the offer of two new zooms addressed just for her.
Both models are full-frame zooms – a wide range of focal lengths. The most interesting proposal is the HD PENTAX-D FA 15-30mm f / 2.8ED SDM WR. 15 mm is a full frame image of a very wide, and 30 mm allow for closer personnel with more blur background. This will help in the further brightness of the lens – f / 2.8. For the construction of the optical glass comprises 18 lenses in 13 groups, including three elements of glass having reduced coefficient of dispersion.The manufacturer made sure that his objective was devoid of undesirable effects of chromatic aberration or distortion. In addition, the lens is equipped with a shell HD, which will be helpful when taking high-resolution pictures. Aperture has 9 blades and sharpen we have 28 centimeters. Autofocus works with the ultrasonic drive Supersonic Direct-drive Motor, which aims to provide fast, silent focus. The lens is also sealed, and its weight is just over one kilogram (1040 grams).
PENTAX 28-105 mm
Another new feature is the HD PENTAX-D FA 28-105mm f / 3.5-5.6ED DC WR. You could say that it was up to the first lens, because its minimum focal length starts at around 30 mm. It is much longer, and allows for much greater approximation, but at the same time has a worse light – standard lenses kitowych, that is, f / 3.5-5.6, and probably just as a lens kitowy will be offered. At its optical construction consists of 15 elements arranged in 11 groups. Two of them are aspherical lenses and one is made of glass ED.Here, too, we used shell HD, giving better quality for photos in high resolution. At the same time prevent the optics of the lens is the formation of undesirable effects, as well as the glare of light, flarom like. In contrast to the model Pentax 15-30 mm is not used here ultrasonic autofocus, so we will have to reckon with slightly louder work. The minimum focusing distance for the glass amounts to 50 cm. It is worth noting that also the lens is sealed, and its weight is relatively low – is less than half a kilogram (440 grams). Both lenses are to appear on sale in April this year. HD PENTAX-D FA 15-30mm f / 2.8ED SDM WR will cost about $ 1500, and kitowy HD PENTAX-D FA 28-105mm f / 3.5-5.6ED DC WR – less than $ 500. Very interesting full frame SLR at a reasonable price, and the good quality lenses – all of this bodes well for the manufacturer and can provide him with a strong position in the market.
