Matt Allard from Newsshooter.com has been hopping around Inter BEE 2015, an NAB-like exhibition that takes place in Japan, reporting on new video gear from established, as well as developing companies. In this particular video, he gets to try out a different type of lens adapter– one that is built specifically to let light leak in from the sides and flare the image as it's recorded in-camera.
As some commenters have pointed out on other sites, the light appears to look as though it has been layered on top of the image, rather than blending in with it. What do you think? I'm a fan of lens flare (depending on the content of the shot of course) in my still photography, and I also use them in post in my video work. These light flares definitely have a different feel to them, and I think they don't blend quite as well as when you do them in post, utilizing a blending mode for example. But the video above shows just one example– it's not a complete test by any means.
It's been suggested that "lens-whacking" is a comparable effect, but in the case of this lens adapter, there is no focus shifting and blur happening. That could be good or bad depending on the effect you're going for.
As of the time of this article being written, the product wasn't listed on the Technical Farm website, so no word on availability or cost. But what do you think? Is this garbage, a fun "trick" piece of gear, or something you would throw in your kit for the right shoot?
