Ok, David Eitelbach needs to take some reading comprehension courses or something. From UCSD news, http
/ucsdnews.ucsd.edu/pressrelease/new_miniaturized_wide_angle_lens_captures_images_in_high_definition. It seems instead of using corrective optics to channel the light into a 'tunnel' to expose the sensor, they used a bundle of optical fibers with specially shaped/polished ends. Oh, and it's a 5MP sensor, however it's likely it was extremely small so the initial lens elements didn't need to be nearly so large.
Part of the reason DSLR lenses are so big is they need to put the light onto a physically large sensor chip. Simple physics.
The article also doesn't mention that this would replace DSLR lenses, merely that it could enable smaller sensors with smaller lenses to have higher quality images without the distortion that traditional fisheye lenses have. Basically, they avoid the geometric distortion that traditional lenses impart by turning 'curved' light into a rectilinear projection onto a sensor.
Next time, please link the original information, and do a better job of actually reading the article, instead of taking 5 seconds to scan it and create a eye catching headline with mis-information in the body.
