Photojojo, purveyors of a wide array of camera accessories, has just announced The iPhone SLR Mount. This accessory will let you mount either a Canon (EF-mount) or Nikon (F-mount) DSLR lenses onto an iPhone 4 and should be available starting in mid-August. This gives you an unprecedented amount of control over your iPhone images. You can now take complex photographs instead of relying on image editing apps that simulate unusual focusing and faux filters.
Using the iPhone SLR Mount gives you the ability to create unique photographs with varying degrees of depth-of-field exposures and also lets you focus your shots manually. 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.
You do lose about 1 to 2 f-stops when using the adapter, so unless you compensate for this, your pictures may turn out a little on the dark side. Its also important to note that traditional SLRs have mirrors inside of them that flip the image as its being captured, so youll have to manually flip your images using an image editor after you take your shots. This is a small price to pay for using high-end glass with an iPhone.
The adapter itself is made up of three parts, an iPhone 4 case, a UV filter, and the SLR lens adapter. Of course youll have to provide your own camera lenses. The iPhone recently became the most used camera on Flickr, surpassing DSLRs and traditional point-and-shoot cameras as well. The camera is no longer a lavish accessory for high-end cell phones anymore, but has become standard equipment. Although The iPhone SLF Mount is a bit pricey at $249, for some photographers, it will undoubtedly become an invaluable tool in their camera bag.
