18-55mm SLR len attach to iphone

A famous camera hacker Bhautik Joshi, who design the brilliant DIY tilt-shift lens hack, has contributed another great idea. It’s an optical coupler that allows an iPhone to accept a standard SLR lens that known as Phone-O-Scope. Though this DIY modification is not powerful enough but it’s good enough to shoot with and produces very analog (almost Holga-like) results. You also get the advantages of SLR lenses – that is, DOF effects, and the wide range of available focal lengths (i.e. macro to telephoto).

The image quality issues are caused by two main factors:

1) Optical axis alignment. When the phone, lens stack and SLR lens alignment isn’t good enough that will cause a small alignment errors in the axis – even as little as one or two millimeters – is enough to cause significant portions of the image to become out of focus

2) Image stack lenses used. The lenses are out of a CD player; they’re not perfect magnifiers, and, they’re designed to work with a specific wavelength of light. This is a significant contributor to the chromatic aberration observed.

Well, I think iPhone manufacturer should consider releasing an real SLR lens for their iPhone, because it’s really a good idea to have an SLR lens attached to our iPhone. Maybe in future not only iPhone, the other phone¬† and smart phone manufacturer like Nokia, Sony Ericson, Samsung, Dopod, HTC will we the first to introduce that extra add on.
