A post over on REDUSER has produced some test shots of the new optical low pass filter (OLPF) for the RED Epic Dragon camera. The new OLPF will be available in just over a month, and solves some flaring and red highlight detail. A camera’s optical low pass filter is designed to remove high frequency information, reducing aliasing and false color. Here’s from REDUSER Jarred: In certain situations the current Dragon OLPF can exhibit a reflected IR flare or magenta glow around bright sources inside or on the edge of Frame in different strengths depending on the light, the angle of reflection, lens etc. Good news is that the new OLPF comes out of the oven en masse in about a month.. and it solves the flare issues as well as fixes a few other optical / IR characteristics that we have seen over the last couple months. And the tests from REDUSER Phil Holland: The Sun. 40 Watt Incandescent Bulb. Single Source Flashlight. A Match. The magenta glow around intense sources is gone. This is great news. You may notice that there are color and “tonal density” improvements. Dragon received a new calibration and update to the color science to play nice with this New OLPF. So you might ask, is the IR Cut still as effective and what’s the net results on the color utilizing hard Neutral Density Filtration? Daylight – ND 2.7 Artificial Daylight Source – No ND. Highlight Retention and Highlight Roll-Off. The results look great, putting the previous filter to shame a little. Fortunately for current RED Epic Dragon users, the upgrade to this new OLPF will be free of charge. For more information check out the REDUSER post.Read more
Further more to the video-able stills camera announcements comes a new consumer level DSLR from Nikon. The D5300 was announced last week and to be honest I overlooked its capability for video, as first impressions lead to believe it didn’t defer very far from its predecessor. On closer inspection, it’s the first Nikon DSLR to offer 1080 50/60p (previous models only offering 50/60i), it has no optical low-pass filter (OLPF) and it has improved lowlight performance.Read more
