HOYA CORPORATION PENTAX Of imaging Of systems Of division presents SMC PENTAX- D FA MACRO of 100mm Of f2.8 WR – high-aperture auto-focal [makroobektiv], created specially for the work with the digital cameras PENTAX. All best qualities of its predecessor – SMC Pentax- D FA Of macro of 100[mm] of f/2.8. – in the new objective they are augmented by firm moisture and dust-protection, which never is excess during the photographing on nature.
Basic special features
1. the outstanding construction
New [makroobektiv] it appears considerably more solidly in the comparison with the existing representatives of a series D FA. Durable and light housing from the metallic alloy possesses outstanding ergonomics. The new construction of focusing ring will make a process of the manual focusing, important for macrophotography, more convenient and more precise. Is not forgotten the firm regime Of quick-Shift, which makes it possible instantly to pass into the regime of manual sharp focusing by the simple turning of focusing ring (after the completion of the process of self-focusing).
2. it is reliable in any situation
PENTAX- D FA MACRO of 100mm Of f2.8 WR is reliably protected from the entry inside the moisture and the dust. Photographer can hundred per-cent be concentrated on the survey by [makromodeley], without fearing, that they will sprinkle/they will sprinkle by pollen or they will somehow still do harm to objective. The unique SP- coating of front lens on the basis of fluorides will make it possible to easily clean products of vital activity of frightened insects from external of glass- objective and to immediately continue macro-contact with them. The inanimate objects of survey (water, sand, food, sparkling beverages) also no longer present danger for the objective – simply you approach as conveniently closely and make excellent photographs, disregarding of the dangerous for the technology properties “of [fotomodeli]” and the unfavorable weather conditions.
3. rounded lobes of diaphragm for guaranteeing the excellent the side
Objective PENTAX- D FA MACRO of 100mmF2.8 WR – first objective PENTAX with the practically absolutely circular diaphragm opening, because of the special form of eight [dafragmennykh] lobes. This innovation makes it possible to attain the staggering soft side and to get rid of the noticeable reflexes because of the point luminous sources.
4. excellent image quality
With the use with the digital reflex camera PENTAX this objective ensures the focal length, equivalent to 153 mm in the size 35 mm, which will allow photographer easy to obtain interesting and spectacular macrophotography with sufficiently large scale 1:1, too without approaching an object. Excellently recommended itself optics classical PENTAX- D FA MACRO of 100mm Of f2.8 ensures staggering high detailing and outstanding high-contrast image without the distortions and the outside gatings.
Furthermore, the special feature of optics PENTAX of a series D FA their lies in the fact that covering field corresponds to the frame dimension of 24[kh]36 mm, which makes it possible to use this objective with the cameras with this frame format.
