Description
The Sony Alpha A7R IV mirrorless camera is a continuation of a series of high-quality, full-size sensor cameras featuring impressive photos and video.
This fourth edition of the A7R is equipped with an updated 61MP Exmor R BSI CMOS sensor and an enhanced BIONZ X image processor that deliver impressive results with smooth transitions and a dynamic 15-step range.
The model offers serial shooting with up to 10 frames per second, UHD 4K30p video, Eye AF real-time support and autofocus tracking. The autofocus system is a Hybrid (Fast Hybrid AF) with 567 points.
The large sensitivity range of ISO 100-32000 makes the Sony A7R IV suitable for use in different lighting conditions. In addition, the sensor relies on 5-axis image stabilization, which is effective to minimize the effect of camera shake by up to 5.5 steps.
Lens Sony FE 24-70mm f/2.8 GM
The Sony FE 24-70mm f/2.8 GM lens is a compact and lightweight standard zoom lens for full-frame cameras with a constant maximum aperture.
The optical scheme includes aspherical elements (including one XA element), one ED and one Super ED element to minimize chromatic aberrations, astigmatism, asymmetric aberrations (coma), etc. The Nano AR coating prevents unwanted flare and ghosting, and the 9-element diaphragm provides impressive bokeh.
The fast and reliable autofocus of the Sony FE 24-70mm f/2.8 GM is provided by the Direct Drive SSM (DDSSM) system, which ensures smooth, precise and quiet autofocus.
The lens has a dust- and moisture-resistant housing and has been developed with the aim of maximum convenience in operation - with options to lock the zoom, the hood, a button to switch between manual and autofocus, etc.
Стандартното мащабиране е подобрено
Постоянно F2.8 24 – 70 mm мащабиране с невиждано досега обединяване на висока разделителна способност и меко боке.
Нова ера на работни показатели на стандартно мащабиране
Дизайн и технология без компромиси в нов постоянен вариообектив F2.8, който може напълно да използва потенциала на работа на съвременни и бъдещи корпуси на фотоапарати с висока разделителна способност.
Несравнима разделителна способност и детайлност
Елементът XA (изключително асферичен) с изключителна прецизност на повърхността работи с ED елементи за невероятна разделителна способност, която може да заснема спиращи дъха текстури и детайли.
Яркост и бързина на F2.8 при всякакво фокусно разстояние
Поддържайте настройките на експонация постоянни в целия диапазон на мащабиране за поддържане на възможност за работа при слаба светлина или спиращи действието скорости на затвора с винаги впечатляващо качество на изображението.
Прецизен фокус със невероятна скорост
Direct Drive SSM (DDSSM) свежда до минимум излишното движение като същевременно изтънчените алгоритми подобряват скоростта на работа на автофокуса. Плавна и тиха работа за филми, както и за снимки.
Професионални функции за управление на обектива
Превключвател за режим на фокусиране, бутон за задържане на фокуса и превключвател за заключване на мащабирането предоставят професионално управление за най-различни ситуации на заснемане.
Конфигурация на обектива
Серията обективи G Master извежда обработката на изображения и изразяването на недостижими преди това нива с невероятна комбинация от изключително висока разделителна способност и нежно преливащо фоново боке.

Схема на MTF
MTF (Функция за предаване на модулация) описва доколко добре обективът може да пресъздава фини детайли, измерена като постигнатата степен на контраст между линии с малко разстояние помежду си.
