Dobry den, je objektiv Sigma 30mm f/2,8 DR ART doopravdy širokoúhelný objektiv? Chtěla jsem ho koupit na focení portrétů. Děkuju
A high-performance model for compact cameras with interchangeable lenses. It belongs to the category of Art and is therefore designed in a sturdy, metal body. It offers the equivalent angle of view as models with the focal length of 45mm on the 35mm format. The basis is two aspherical lenses, one of which is two-sided, which facilitates to gain a high-level correction of all types of aberrations. The internal focusing system does not extend the lens, so that corrects the fluctuation of aberration and maintains a high quality of the image.
The multi-layer coating (Super Multi-Layer Coating) helps to reduce flare and ghosting, as well as provides sharp and high-contrast images even at the maximum aperture. Its advanced design also helps to ensure that the lens can be lightweight and compact. The linear motor, which moves the lens elements directly without the need for any additional mechanical elements, is used for high-precision focusing. This system ensures accurate and near-silent autofocus, making the lens suitable for video recording and taking photos. Due to the 7 circular diaphragm blades, the lens creates an attractive bokeh.

Názor, který si nechci nechat pro sebe: Ahoj kamarádi, tohle sklo všem doporučuji, ohnisko (na APS-C) velice použitelné, dost krátké, aby se vám v 70% případů do záběru vše vešlo a zároveň dost dlouhé, aby při F2,8 objektiv produkoval malou hloubku ostrosti s velice příjemným bokehem kontrastujícím s nekompromisní ostrostí v rovině zaostření. Světelnost neni zázračná, ale kdo nechce do univerzálního objektivu na běžné focení (výdorného na focení lidí a detailů) moc investovat, nebo vyžaduje maximální kompaktnost, tak tohle je jasná volba. V poměru ceny a výkonu je to jedno z nejlepších skel co jsem zkusil (a to mám i G a Zeiss objektivy...). Vlastním i 19 a 60mm a s touhle trojcí (+ mezikroužky) dělám 90% fotek. Zdar a dobré světlo!
