Тип обьектива

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.

Профиль обьектива

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.

Описание модели

Canon EF 28-300/F3.5-5.6 L IS USM

The professional photographer's superzoom.

A true all-in-one lens
With a zoom range covering everything from wide-angle to super-telephoto, Canon's latest professional series is designed for professional photographers looking to limit lens changes and reduce overall kit weight. Perfect for photojournalists and those shooting on the move.

Three-stop Image Stabilizer
The IS technology built-in to the EF 28-300mm f/3.5-5.6L IS USM lens provides a three-stop advantage in low light conditions. This enables slower shutter speeds to be used without incurring blur from camera movement – useful when a situation does not permit the use of a tripod or flash. If the lens senses the photographer is panning to follow a moving subject, it switches off IS in this direction.

Ultrasonic focusing
A ring-type ultrasonic motor drives autofocus extremely quickly, and in near silence. Excellent holding torque ensures the point of focus is reached accurately, without overshooting. Furthermore, full-time manual override is available, making it possible to adjust focus without leaving AF mode.

Perfect for digital
Lens shape and coatings have been optimised to suppress ghosting and flaring, making the EF 28-300mm ideal for use with digital cameras. When fitted to DSLRs with an APS-C size sensor, the lens has an equivalent focal length range of 45-480mm.

Precision optics for high image quality
Beautiful contrast, low distortion and high corner-to-corner resolution is evident throughout the zoom range. An EMD (electromagnetic diaphragm) gives fast, quiet, highly precise aperture control. A circular aperture diaphragm affords pleasing background blur.
