It's fair to say that, however lovely the iPhone, its 2-megapixel camera is yet to blow anybody away with the visual splendour of the images it produces.  Brando are looking to, if not improve them as such, then at least let you take mediocre shots closer to your subject, thanks to a 6x optical zoom accessory.

Attaching via a clear plastic shell for the iPhone, meaning you don't have to glue it to your handset (which might make fitting it into a trouser pocket somewhat embarrassing), the lens also has manual focus control.

It's available now for $19.
