大片幅感光元件 最近來愈來愈熱，隨著微單系統興起，全幅感光元件正式進入無反光鏡的數位相機領域
小弟今天想聊聊 全幅機身，並且開始正視全幅相機的在今天的一些優點、特色
小弟先列一些全幅相機特色
(1). 畫素 與 價格 之 最均衡比例
(2). 鏡頭收光 與 成像 之 最美妙多元的變化程度
(3). 機身 與 鏡頭群 之 最主流的近代規格
(4). 廠商生產成本 與 攝影成品 之 最具效益的專業攝影產品
(2) 全片幅鏡頭可收入的光線影像資訊較多，(APSC、43系統 或更小片幅感光元件所能收集的資訊都明顯較少)。全幅成成像相片的 景深變化、影像的解析度都算是較豐富、較有特色。
(3) 老鏡、新鏡鏡頭豐富，全幅反光鏡相機已有大量的鏡頭群。也延續上面第二點，。預期未來全幅無反規格興起後，此熱潮將更盛。
(4) 全幅的效益。今天數位全幅感光元件，已經完全與135底片不同了。全幅感光元件收進的影像資訊相當的細緻，以前135底片的影像顆粒度反而非常粗糙。雖然底片的反差較小、灰階層次較多。但數位感元件透過數位暗房，也可以讓層次變多。(相反來看，其實層次本來就在，只是機身自動產生色階反差較高的RAW檔，讓相片看起來比較討喜)
全幅的效益，也不需要抽象的天花亂墜，舉實例來說，專業攝影、婚紗攝影、婚禮，舉凡對影像有較重度要求，全幅幾乎是最基本的攝影條件。其實，若消費者希望廠商 推出更多消費者期望的產品，除了廠商研發主動推出。
歷史證明，會吵的人有糖吃!!!消費者 支持及大量反映自身需求，才是推動廠商未來全力走向 全幅元件 重要推動力。

某大陸友站：关于镜头感：28-35-50（基于全画幅）
I 100% agreed with your statement.
1. Full frame is much needed for certain professional, period. For average or even advanced photographer, full frame is nice to have but not much needed. For us, we need much more better AWB, better color processing JPEG and lighter and smaller. Weight is becoming a big issue to consider.
2. I am less optimistic about m4/3 but I think APSC is here to stay.
Recently, I become more and more interested in Rangefinder camera. I am using a used RD-1 from Epson and really surprised how a 2004 camera can have such an accurate AWB. It put Canon, Nikon all to shame. If you look at M lens, every effort is being spent on how to correct optical or color issue with utmost effort in lens material and design, while keeping the size and weight as compact as possible. If you look at Nikon designer today, they are way too lazy, distortion of all sort, on native scale, was so large and unacceptable and yet, they think they will use electronic image processing to correct somewhat. The biggest problem facing with Nikon or Canon designer is that, they think everyone will use Lightroom to process RAW, so they leave a lot of that to post-processing. To me, that is lazy and incompetent. Yes, even Leica M240 relies on 6 bit coding to do some correction but no one doubts that Leica M lens, in its native scale, is optically superb. Yes, they cost a lot more but still, if you look at modern 1.4 lens, they also cost a lot more nowaday.
Bottom line, choose and use camera of your choice and your usage. That is an easy to say but hard to understand advise as most of us, do not understand what we need, as a camera, for our needs or what we think we do. Personally, I am deeply entrenched into a rangefinder and a Fuji system. Rangewinder is a joy and fun but it is not for everyone. The same is true for full-frame versus non-full-frame sensor.
Hope this helps.
