İnsan gözü çözünürlük ve algılayabilme kapasitesi açısından tarihin her evresinde üretilen bütün görüntüleme cihazlarına ilham kaynağı olmuştur ve şu ana kadar insan gözünün algılama kapasitesine sahip bir cihaz üretilememiştir.( diye biliyoruz)
Sony’nin aynasız makinelerinin en günceli olan Alfa 7S II sergilediği düşük ışık performansıyla bir çok kullanıcının iştahını kabartmaktadır. Videoart GR isimli Youtube kanalında yayınlanan son videoda ise insan gözüyle A7SII kıyaslanmakta ve ortaya çıkan sonuç ise oldukça ilginç. Videoyu aşağıdaki bağlantıdan izleyebilirsiniz.
