前一段時間有人給iphone4加了個三鏡頭插件，使得iphone4可以完成魚眼、長焦以及廣角的效果。現在又推出了最新的iphone單反插件，讓iphone4也能作為單反相機使用。該插件有兩個版本，分別是F-mount adapter專為尼康鏡頭設計，而EF-mount adapter則可以搭配Canon EOS鏡頭。該插件有兩個部分，分辨是裝在iphone4身上的機殼和與鏡頭配套的連接頭。只要花249刀您就可以買入“旅遊窮三代，單反毀一生”的快樂小日子。

　　If you’re in love with your iPhone 4 and use it as your go-to camera for everyday pics, but meanwhile, your SLR lenses are gathering dust, you may want to explore a way to get the best of both worlds. If you want to expand the camera capabilities of the iPhone 4, a new lens mount that accepts SLR lenses just might be the answer to your prayers.

　　“This case-adapter combo lets you mount your Canon EOS or Nikon SLR lenses to your iPhone 4 giving your phone powerful depth of field and manual focus. Telephoto, wide angle, macro, or your fixed-fifty lenses all attach to this mount giving you a full range of lenses at your iPhone lovin’ fingertips.”

　　While this adapter gives you a world of different choices for phone photography, there are a few drawbacks, including the fact that because the iPhone camera is mirror-less, all photos will be upside down (which can be solved using an app), and it is necessary to manually focus so that you’re not just taking close-ups of the focus screen on the mount. But considering how much more amazing your phone photos will be, those are pretty small drawbacks.

　　There are two versions of the mount adapter, an F-mount adapter for Nikon, said to work with all Nikon lenses, and an EF-mount adapter for Canon EOS lenses. Made from aluminum, the iPhone SLR Mount also has two loopholes on each end of the case for a camera strap, and sells for $249 at Photojojo.
