Objektyvo serija Sigma
Objektyvo tipas

Objektyvų tipai būna: kintamojo fokusavimo ir fiksuoto fokusavimo.

Fiksuotas reiškia nustatyto židinio nuotolio objektyvą, kuris neturi priartinimo funkcijų (be galimybės keisti židinio nuotolį). Fiksuoto židinio nuotolio objektyvas yra universalus, juo galite užfiksuoti kraštovaizdžius, architektūrą, momentines nuotraukas, portretus tik vienu objektyvu. Jų būna įvairių: plačiakampiai (židinio nuotolis 10-30 mm), vidutiniai (50-100mm) ir teleobjektyvai (200-1200 mm).

Kintamo židinio nuotolio objektyvai turi platų matymo kampo diapazoną viename objektyve. Jie yra labai populiarūs dėl galimybės keisti matymo kampą nekeičiant paties objektyvo. Patogią priartinimo funkciją pritaikysite viskam – nuo laukinės gyvūnijos fiksavimo saugiu atstumu iki vaikų fotografavimo nepertraukiant jų užsiėmimų.

Fiksuotas fokusavimo atstumas
Objektyvo profilis

Pagrindiniai objektyvų profiliai: standartinis, tele, plataus kampo, žuvies akis ir macro.

Standartinių objektyvų matymo kampas yra analogiškas žmogaus akies matymo kampui (~50°).

Su teleobjektyvais dažniausiai fotografuojami objektai kurie yra nutolę nuo fotografo ir nėra galimybės prieiti arčiau jų pvz. fotografuojant drugelį ar paukštį prie kurių priėjus arčiau jie tiesiog nuskristų.

Plataus kampo objektyvas talpina platų vaizdą. Jis labai praverčia tuomet, kai į fotografiją reikia sutalpinti kuo daugiau - „nufotografuoti platesnį kampą“. Tai aktualu fotografuojant interjerą, buitines scenas, architektūrą, gamtovaizdį. Plataus matymo kampo objektyvai vaizdą „užlenkia“ kraštuose ir pasižymi dideliu vaizdo ryškumu.

Žuvies akies objektyvai turi dar platesnį matymo kampą nei plataus kampo objektyvai, jis siekia net 180°, bet didelis vaizdo iškraipymas, nufotografuotas vaizdas bus smarkokai „užlenktas“ į kampus, riboja jų panaudojimą.

Makroobjektyvai leidžia stambiu planu fotografuoti labai mažus objektus ir atskleidžia plika akimi nematomas detales. Juos naudoja laukinės gamtos fotografai, fotografuojantys vabzdžius ir gėles.

Standartinis: 18 - 55 mm

Prekės aprašymas

Sigma 30 f/1.4 DC DN Contemporary for Sony-E Mount
Prekės aprašymas anglų kalba:

A fast, versatile prime, this 30mm f/1.4 DC DN Contemporary Lens from Sigma is designed for APS-C-format Sony E-mount mirrorless cameras, where it provides a 45mm equivalent focal length. The bright f/1.4 maximum aperture benefits working in low-light conditions and also affords extensive control over focus placement for using selective focus techniques. In regard to the optical design, one aspherical element and one double-sided aspherical element pair to significantly reduce spherical aberrations for increased clarity and definition for notably sharp image quality. A high-refractive index element is also featured, to minimize color fringing and chromatic aberrations, and a Super Multi-Layer Coating has been applied to control lens flare and ghosting in strong lighting conditions. Additionally, benefitting both stills shooting and video recording, this compact prime also incorporates a stepping AF motor or smooth, near-silent autofocus performance. Designed as a versatile standard lens, the mixture of speed and optical prowess make this a go-to lens for mirrorless shooters.

  • A truly versatile standard prime, this 30mm lens is designed for APS-C-format Sony E-mount mirrorless cameras where it provides a 45mm equivalent focal length.
  • Fast f/1.4 maximum aperture excels in low-light conditions and also affords greater focus control for producing shallow depth of field effects.
  • One aspherical element and one double-sided aspherical element control a range of spherical aberrations and distortions for increased sharpness and resolution. Additionally, a high-refractive index, high-dispersion glass element is also integrated into the design, and offers anomalous partial dispersion characteristics to control chromatic aberrations and reduce color fringing.
  • A Super Multi-Layer Coating has been applied to lens elements in order to minimize lens flare and ghosting and contribute to producing contrast-rich and color-neutral imagery, even in backlit conditions.
  • A stepping AF motor benefits both photographers and videographers with its fast, precise, and near-silent performance.
  • A rounded nine-blade diaphragm contributes to a pleasing bokeh quality.
  • The lens is constructed using a Thermally Stable Composite (TSC) material, along with traditional metals, for greater precision and use in wide temperature variations. The outside of the lens barrel is also engraved with the year of production.
  • The bayonet mount is constructed from brass for ensured accuracy and durability.
