SMC PENTAX DA 40mm F2.8 XS のスペック
- 最大光圈： F2.8
- 最小光圈： F22
- 鏡片構成： 4群5枚
- 畫角： 39度
- 最大攝影倍率： 0.13x
- 光圈葉片枚数： 9枚
- 濾鏡口徑： 27mm
- 最大直徑與長： 62.9mm x 9.2mm
- 重： 52g

鏡尾有刻意突出的組件, 看來真是DSLR對應不能? ← 哈在下耍蠢了, 忘記有光圈連動桿 XDDDD
或許是售價會非常便宜吧, 那...又會掀起一波改鏡潮嗎? XD

Pentax薄型鏡頭設計功力真是滿強的,
若能補齊焦段(40小遠, 若來個30/15 XD, 美妙), 並維持低價策略擴充XS餅乾鏡群,
再輔以目前母廠RICOH的調校功力, 似乎也是個前景良好的新系統呢 :)

不需轉接環便可沿用K鏡, 但仍保有整體輕便度(搭配XS鏡時), 讚!

剛看到K-01單機身 749美金
40mm XS kit 899美金
換言之 拆鏡價大約150美金左右
應該還算合理吧

拿了手邊的Nikon"機身蓋\"來量，厚度(長): 7.0mm

如果實品就是照片這樣
那這顆大概只是將DA 40mm F2.8 Limited外觀修改的版本
http://pentaxplus.jp/focus/lens/003/003d/index.html
光學規格都一樣
是把原DA40 LE前緣裝遮光罩49mm口徑的地方以及距離尺表去掉
來達到極小化目的的新版本

原來DA40 LE價錢約一萬初(日幣未升值前還只要八千多)
這顆必然可以更便宜(但遮光罩跟鏡頭袋應該就沒有附屬了)

接環是KAF也就是由機身馬達驅動對焦
所以沒意外
是可以裝上DSLR
甚至裝在底片機上也可以拍(原來DA40是可以的)

由情報圖片看來K-01所搭售的鏡頭都還是KAF鏡
DA40 XS
DAL18-55
DAL55-300

之後不知道會不會也有
DA 21mm F3.2 AL XS
DA 70mm F2.4 XS

The Pentax DA 40mm f/2.8 XS Lens is specifically designed for the APS-C sized Pentax K-01 mirrorless camera. The 40mm focal length is equivalent to 61mm on a 35mm format, and provides a slightly longer angle of view than normal. It features a maximum aperture of f/2.8 for low and existing light photography and greater control of depth of field. In addition to the wide aperture, the 9 rounded aperture blades help to provide a smooth bokeh that is accentuated in the highlights when photographing wide open. This prime length lens is ideal for general purpose photography and has a minimum focus distance of only 15.72" / 39.93cm for close up work.

This lens also features a highly aesthetic, minimal design by famed industrial designer Marc Newsom. The low profile measures 0.36" / 9.1mm thick and weighs 1.8oz / 51g. Pentax' SP (Super Protect) coating on the lens surface helps to repel moisture, dust, and dirt while providing greater clarity, contrast, color fidelity. The lens is compatible with the KAF mount and supports autofocus and automatic diaphragm controls.

這隻網路上有買拆鏡價 7500，算合理價格嗎？

這隻鏡頭到底能不能裝在 DSLR 上使用？我目前還在用 K10D...

絕對可以用在DSLR上
K-5銀色特別版就是跟這顆鏡頭搭在一起賣的

所謂有圖有真相

對!~ 這支鏡頭非常特別
小弟雖出脫機身，但留下這支鏡頭
轉接在NEX-7 上效果也很好
全光圈，邊角失光非常輕微
不像是APS-C的轉用鏡

現在連全幅都可以涵蓋(雖然邊邊有點鬆濛)
但可見這支鏡頭設計還滿不錯的

引文:

其實原先的 DA 40/2.8 LE 就可以在135上使用
甚至是所有35mm以上的DA定焦鏡,幾乎都可以在135上使用

這邊有統計資料
