S\u00a0fototechnikou zna\u010dky Olympus sa kamar\u00e1tim u\u017e p\u00e1r rokov. Za\u010dalo to fotoapar\u00e1tom Olympus E-M10 II<\/a> a\u00a0objekt\u00edvom Olympus M.

Pred p\u00e1r mesiacmi som doplnil svoju techniku o\u00a0vlajkov\u00fa lo\u010f Olympusu, model E-M1 II. Rozl\u00ed\u0161en\u00edm to s\u00edce nie a\u017e tak\u00fd v\u00fdrazn\u00fd skok oproti E-M10 II, ale nad ostatn\u00fdmi parametrami \u017easnem doteraz. V\u00a0danej triede doslova dokonal\u00fd AF, a\u00a0to m\u00e1m na mysli najm\u00e4 u\u00a0bezzrkadloviek tak diskutabiln\u00fd AF-C, ktor\u00fd str\u010d\u00ed do vrecka nejednu zrkadlovku aj z\u00a0radu full frame, skvel\u00e1 ergon\u00f3mia, kreat\u00edvne mo\u017enosti nastavenia a\u00a0kone\u010dne aj v\u00fdborn\u00e1 v\u00fddr\u017e bat\u00e9rie. Fotoapar\u00e1t nos\u00edm ako jeden z\u00a0troch fo\u0165\u00e1kov aj na svadby a\u00a0moje o\u010dak\u00e1vania sp\u013a\u0148a na 100%.

V\u00a0j\u00fali tohto roku sme s\u00a0man\u017eelkou absolvovali dovolenku v\u00a0N\u00f3rsku. Po dlh\u0161ej \u00favahe, ako \u010do najefekt\u00edvnej\u0161ie skombinova\u0165 svoju fototechniku, som k\u00a0telu E-M1 II zvolil ultra – \u0161irokouhl\u00fd objekt\u00edv Olympus M. ZUIKO DIGITAL ED 8mm f\/1.8 Fisheye PRO<\/a>. E\u0161te st\u00e1le jeden z\u00a0najnov\u0161\u00edch pr\u00edrastkov v\u00a0profi rade Olympusu ma zaujal u\u017e na jarnom \u0161kolen\u00ed a\u00a0N\u00f3rsko so svojimi nekone\u010dn\u00fdmi scen\u00e9riami mi pri\u0161lo ako ide\u00e1lne miesto na jeho otestovanie.<\/span><\/p>\n

Objekt\u00edv v\u00a0praxi<\/strong><\/span><\/p>\n

Objekt\u00edv patr\u00ed medzi tie men\u0161ie v\u00a0profi rade a\u00a0na relat\u00edvne ve\u013ekom tele E-M1 p\u00f4sob\u00ed nen\u00e1padne. O\u00a0to viac zaujme svojim v\u00fdkonom. Foti\u0165 m\u00f4\u017eete do RAW form\u00e1tu a\u00a0v\u0161etko potrebn\u00e9 nastavi\u0165 a upravi\u0165 v\u00a0raw editore. T\u00e1to kombin\u00e1cia v\u00e1m zabezpe\u010d\u00ed v\u00a0pr\u00edpade \u0165a\u017e\u0161ej svetelnej sc\u00e9ny lep\u0161ie vyu\u017eitie dynamick\u00e9ho rozsahu sn\u00edma\u010da, \u0161ir\u0161\u00ed z\u00e1ber ke\u010f\u017ee ide o\u00a0typick\u00fd, s\u00fadkovito skreslen\u00fd, 180\u2070 z\u00e1ber ako sa patr\u00ed na rybie oko. Foti\u0165 ale m\u00f4\u017eete priamo do jpeg a\u00a0tu pre m\u0148a prich\u00e1dza najpozit\u00edvnej\u0161ie prekvapenie.<\/span><\/p>\n

Objekt\u00edv m\u00f4\u017eete v\u00a0menu, v\u00a0\u010dasti J1 nastavi\u0165 na tri r\u00f4zne ohnisk\u00e1, resp. kompenz\u00e1cie rybieho oka, ktor\u00e9 odhadom poskytuj\u00fa 12 mm, 16 mm alebo 20 mm ohnisko, bez toho, aby v\u00fdsledn\u00fd sn\u00edmok str\u00e1cal na rozl\u00ed\u0161en\u00ed. Tak\u017ee v\u00a0podstate dost\u00e1vame objekt\u00edv 12-20 mm f\/1.8, \u010do je unik\u00e1t vo svete fototechniky. Softv\u00e9r fotoapar\u00e1tu zabezpe\u010d\u00ed primeran\u00fa korekciu l\u00edni\u00ed pre dan\u00e9 ohnisko, tak\u017ee sa v\u00f4bec nemus\u00edte tr\u00e1pi\u0165 t\u00fdm, \u017ee okrajov\u00e9 \u010dasti sc\u00e9ny budu nepou\u017eite\u013en\u00e9, ako to b\u00fdva pri objekt\u00edvoch typu fisheye. Ur\u010dit\u00e9 skreslenie tam je, ale v\u0161etko v\u00a0r\u00e1mci be\u017en\u00fdch vlastnost\u00ed profesion\u00e1lnych ultra- \u0161irokouh\u00fdch objekt\u00edvov. Skvel\u00e9!<\/span><\/p>\n

Ostros\u0165 objekt\u00edvu je ve\u013emi dobr\u00e1. Korekcia r\u00f4znych optick\u00fdch ch\u00fdb ako vinet\u00e1cia, aber\u00e1cia a\u00a0u\u017e spom\u00ednan\u00e9 skreslenie je rovnako ve\u013emi dobre korigovan\u00e9. Objekt\u00edv nem\u00e1 probl\u00e9m s\u00a0protisvetlom, odlesky sa ob\u010das zjavia, ale vzh\u013eadom na vypukl\u00fa kon\u0161trukciu predn\u00e9ho \u010dlena je to viac ne\u017e skvel\u00fd v\u00fdsledok.<\/span><\/p>\n

Na z\u00e1ver to najlep\u0161ie, hovor\u00ed sa. Pre m\u0148a je to svetelnos\u0165 f\/1.8, ktor\u00e1 je unik\u00e1tna v\u00a0tejto kateg\u00f3rii objekt\u00edvov. \u010co to znamen\u00e1 v\u00a0praxi?

Sk\u00fa\u0161al som 3 aj 5 sekundov\u00fa expoz\u00edciu a\u00a0tie fotografie boli st\u00e1le ostr\u00e9. Nie, neznamen\u00e1 to, \u017ee v\u00fdrobcom stat\u00edvov odzvonilo, no ak nepl\u00e1nujete foti\u0165 star trails alebo dlh\u00fdm \u010dasom rozmazan\u00e9 oblaky a\u00a0vodu, tak si nemus\u00edte v\u00a0polovici t\u00fary \u0165uka\u0165 na \u010delo, \u017ee ste si zabudli pribali\u0165 stat\u00edv.

Rozostrenie je vzh\u013eadom na kateg\u00f3riu objekt\u00edvu pr\u00edjemn\u00e9, prechody hladk\u00e9, tak\u017ee pri troche fant\u00e1zie s\u00a0ak\u00fdm ohniskom vlastne pracujeme sa d\u00e1 so sc\u00e9nou ve\u013emi zauj\u00edmavo vyhra\u0165.<\/span><\/p>\n
