Major camera makers including Olympus, Samsung and Sony have all filed patents in recent days for liquid lens technology. Unlike traditional glass lenses, liquid lenses don’t have any moving parts. Instead, liquid is used to focus light, and different voltages are applied to the liquid to change the shape of the liquid, thereby controlling the image. In the video above, techie Ben Krasnow introduces the technology, and then shows off a device he made by ripping a liquid lens out of a USB webcam.

According to Hoya founder Shigeru Yamanaka’s grandson, Yutaka Yamanaka, Hoya’s acquisition of Pentax may not have been the best business move. The younger Yamanaka said the $1 billion acquisition in 2007 was made mostly to expand Hoya’s involvement in medical optics, but turned out to be “overpriced.” Yamanaka, a Hoya shareholder, went so far as to say it was one of Hoya’s business “failures” which led to financial turbulence over the last three years until Pentax turned profitable.
In spite of Yamanaka’s disapproval of the Pentax purchase, it’s rumored that other companies might be interested in buying up Hoya’s unwanted acquisition. Canon Rumors reports that Canon attempted to buy Pentax, perhaps in order to control more of the DSLR marketshare, in direct competition with Sony. Sony may also be interested in Pentax’s user base. But so far, no word on whether Hoya’s ready to hand off Pentax anytime soon.
These glasses might look like typical geeky photo dad gear or something your eccentric uncle might wear, but if your eyes have uneven prescriptions, they can come in handy while shooting. That is, unless you’re classy enough to have a monocle (or contacts).
California-based photo accessory company, Hoodman, showed off this pair of glasses for photographers at PMA earlier this week. The glasses can be set with corrective lenses from an optometrist, and each lens can be individually flipped up. Corrections for the shooting eye can be adjusted with the camera’s diopter, remaining unhindered by an extra layer of glass, while the tracking eye can still benefit from corrective lenses.
