【如何學攝影】ff apsc m43 感光元件是什麼？為什麼焦段會改變？完整原理講解！ 人像粉專: instagram enzos.portraits. 第一步影片主要是在講各家感光元件大小 以及焦段為何會改變 這裡文章在講解一些 ff apsc m43就是感光元件大小不同 我舉例這三個的原因是 以目前市場來說這三個感光元件大小孩是最常見的三種 當然還有中片幅(比全片幅大 所以焦段是要縮減的) pentax q系統 nikon 1系統等等 只是ff apsc m43還是比較容易.
The longer focal lengths from larger sensors do mean a larger aperture size. since aperture size = focal length divided by f stop. so a 50mm f1.4 lens on ff has twice the diameter of a 25mm f1.4 on 4 3. the larger diameter of the aperture means the blur discs are twice as large, too. hence, double the blur at same aperture and efl. So imagine we're looking at a ff image on a 24mm f1.4 ff lens, and then you only keep the center (1.5x crop), you're getting a 24mm cropped which gives a similar look (but not the same) as a 36mm focal length, and it will not look like a 36mm f1.4 at all because the dof didn't change, it will have a dof close to what you get from a 36mm f2.1. The aps c sensor is generally smaller than the full frame sensor and more significant than the micro four thirds sensor and measures around 25.1mm x 16.7mm. however, unlike the m43 sensors, the aps c sensor size varies across brands, with some being smaller than others. for instance, aps c sensors from brands such as pentax, nikon, and the sony. 我来公平公正的谈谈aps c和m43 从两个方面,1是机身 2是镜头体系. 1\机身 aps c各微单其实底来说都一样,底大一级这也是事实,操控来说除了nex7,现在的a6000,其他操控真不怎样,现在的全副a7不在讨论范围. 机身m43,松下奥巴两家,一种是sony底,一种是松下底,早期松下底不.
