夢幻 大光圈 Voigtlander Nokton 25mm F0.95 評測報告

夢幻 大光圈 Voigtlander Nokton 25mm F0.95 評測報告: 誰說大光圈淺景深是只有 DSLR 才能辦得到，近年來隨著 Micro 4/3 與 Sony NEX 這類採用大片幅感光元件機種的問世，除了帶給消費者輕巧的機身體積與高水準的畫質表現外，最讓玩家們驚豔的則是 大光圈 淺景深 效果的呈現。而有鑑於隨身相機的市場越來越大，去年底國際鏡頭大廠 Voigtlander 便特別推出 Nokton 25mm F0.95 鏡頭，讓Micro 4/3 玩家也能輕鬆拍出迷人的夢幻散景。下面就來看看它的試拍效果吧！

超大光圈與優質鏡身

Voigtlander Nokton 25mm F0.95為福倫達以Micro 4/3接環所推出的首支全手動鏡頭，採用25mm焦段，讓玩家在經過焦長轉換後能取得與135mm等效50mm視野，構圖上可更為直覺自然。在鏡身方面，採用金屬材質所打造設計，雖然拿起來有些許沉重，但實際摸起來做工卻是相當地紮實有質感，頗有過去底片時代德系老鏡所流傳下來的歲月感受。光圈使用上，本鏡特別之處在於它擁有超乎我們常見的F0.95大光圈，讓玩家在針對淺景深人像、夜間風景，與室內微光的拍攝時，能更加得心應手，輕鬆搭配高感光來捕捉純淨自然的燈光氣氛，就算是在光圈全開的情況下，此鏡依然擁有不錯的畫質表現。

▲F0.95 大光圈能夠輕易製作出美麗的夢幻散景。

▲微光環境下大光圈能有效輔助影像的捕捉。

 

操作手感與畫質表現

由於此鏡是採全手動拍攝，因此安裝在機身時，並無法以AF自動對焦來驅動，必須先將GF2等M4/3機種以無鏡頭拍攝做設定，才能再進一步以放大合焦的方式進行拍攝。實際操作下來，它在對焦行程與阻尼的設計上非常棒，拍攝時只要順著旋轉，即可順暢且準確地達到自己想要的對焦位置。在畫質表現上，雖然全開光圈並沒有想像中的銳利，不過卻給於影像一種柔順韻味，尤其用在人像拍攝時格外好看，但還是建議讀者在拍攝時可將光圈略為縮小到F1.4，不僅可將影像畫質恢復到它該有的銳利表現，在現場影像的色彩還原上也將會更加自然、亮眼。

Happy Wednesday everyone!  I thought today might be a good day for another random little round up with a few of the pretty paper good­ies that have caught my eye recently.  Enjoy!

I love these “I Give Thanks For___” cards from Satsuma Press.  Such a wonderful idea for the Thanksgiving holiday, or even to help start a new year in January.

Showcase of 20 Photos that Utilize Textures Well

Showcase of 20 Photos that Utilize Textures Well:

In photography today, texturing is beginning to develop into a well-used practice in photo processing. Looks can range from distressed paper to the addition of grains and even words. This can be achieved by overlaying the subject photo with a textured image. Contrast and blending is all up to the photographer or artist, and can be edited using opacity levels and blending modes. The following photographs are the result of texture processing.

As seen in the above artists’ work, the extent of a photo’s texturing can be subtle or dramatic. A single, well-adjusted overlay can be placed to produce one effect while many layers can be combined for a visually pleasing collage of textures and grains.
