Cel Mai Larg AF Prime pentru APS-C<
/h3>
<
p>
La 9mm (echivalent 13.5mm pe full-frame), acesta este cel mai larg obiectiv prime cu autofocus de pe piata pentru APS-C. Unghiul de <
strong>
113.8°<
/strong>
incadreaza vista panoramica completa, interioare stramte sau cer instelat amplu. Este un obiectiv <
strong>
rectiliniar<
/strong>
(nu fisheye) &
mdash
liniile drepte raman drepte, esential pentru arhitectura si interioare, cu distorsiune nativa minima.<

Compact si Usor - 175g<
/h3>
<
p>
Caracteristica definitorie a seriei Air: la doar <
strong>
175g<
/strong>
(versiunile Sony E si Fuji X
~195g pe Nikon Z) si dimensiuni de 65x57mm, este surprinzator de mic pentru un ultra-wide. Are <
strong>
focalizare interna (IF)<
/strong>
&
mdash
elementul frontal nu se roteste si nu se extinde. Intra in orice geanta si nu te incarca la sesiuni lungi de travel sau drumetii.<

Optica Complexa cu 13 Elemente<
/h3>
<
p>
Structura optica de <
strong>
13 elemente in 11 grupe<
/strong>
include <
strong>
2 elemente aspherical<
/strong>
, <
strong>
3 elemente ED<
/strong>
(dispersie extra-redusa) si <
strong>
3 elemente HR<
/strong>
(indice de refractie ridicat) pentru control eficient al aberatiilor cromatice si distorsiunii. Coating HD Nano multistrat reduce ghosting-ul si flarele, inclusiv in lumina puternica. Claritate edge-to-edge remarcabila chiar de la f/2.8.<
/p>
<
h3>
Autofocus STM Silentios<
/h3>
<
p>
Motorul <
strong>
STM<
/strong>
ofera autofocus intern rapid si silentios, potrivit pentru foto si video. Focus breathing minim. Datorita unghiului ultra-larg si profunzimii mari de camp caracteristice, stabilizarea optica nu este necesara la aceasta focala.<
/p>
<
h3>
Focus Apropiat 0.13m - Perspective Dramatice<
/h3>
<
p>
Distanta minima de focalizare de <
strong>
0.13m<
/strong>
permite apropierea de subiect pentru perspective dramatice cu prim-plan proeminent si fundal vast &
mdash
un efect tipic de ultra-wide care creeaza compozitii imersive cu adancime puternica. Util pentru travel, food si compozitii creative.<
