以往數位單眼相機始終給人於高單價、操作複雜而且不易攜帶的印象，所以數位單眼相機始終是專業攝影師或少數高階相機使用者的照相工具。
然而自從2008年數位微型單眼相機(稱作MILC或EVIL)出現後，許多相機廠商推出輕巧，且價格相對便宜的數位微型單眼相機，數位單眼相機市場已然掀起了一場革命。數位微型單眼相機的問世，除了給專業用戶在相機購買選擇上更多元外，也能吸引更多使用者能夠進入相機的世界，因為數位微型單眼相機除了在體積與重量上有絕對優勢外，其拍照畫質不輸專業型數位單眼相機。
本研究將藉由ANP網絡層級分析作為基礎，以價格、品牌、產品功能三大主準則與八項次準則為研究架構欲探討探討使用者在選購微型單眼相機上之關鍵因素流程，其研究結果顯示三大主準則與八項次準則予以保留，而使用者最重視的選購因素依序為產品功能、價格、品牌。而其研究結果將提供各大相機廠商作為掌握未來產品開發及市場發展競爭優勢利基做為參考。
The digital single-lens reflex camera used to give the impression of high price, complex operation and being difficult to carry; thus it became the tool of professional photographers or a few advanced camera users.
However, with the advent of the mirrorless interchangeable lens camera (MILC or EVIL for short) in 2008, many camera manufacturers have launched in succession light and relatively low-priced mirrorless interchangeable lens cameras, and brought about a revolution at the digital single-lens reflex camera market. The advent of the mirrorless interchangeable lens camera not only provides more purchasing options to professional users, but also attracts more consumers to the camera world, as the mirrorless inter-changeable lens camera has superior photographing quality compared to that of the spe-cialized digital single-lens reflex camera, in addition to its absolute advantages in vol-ume and weight.
Based on the ANP network hierarchy analysis, this research intended to explore the crucial process factors in the consumer’s selection of mirrorless interchangeable lens camera with the research framework of three main criteria of price, brand and product’s functions and eight sub-criteria. The research results indicated that, with the framework of three main criteria and eight sub-criteria, the purchasing factors in order of im-portance for users are: product’s functions, price and brand. Hence the research results may serve as some reference for camera manufacturers to fill the niche market of prod-uct development and competition in the future.
